Introduction
Two technology paradigms will reshape future economic development at the regional level: green technology (GT), which mitigates the negative environmental impacts of innovations, and whose regional dimensions are explored within the geography of sustainability transitions literature (Hansen and Coenen, 2015;Truffer and Coenen, 2012), and digital technology, which is digitizing innovation activities and transforming economic processes through new technologies and applications such as artificial intelligence (AI) (Balland and Boschma, 2021;Capello and Lenzi, 2021;Corradini et al., 2021).The emerging concept of a "twin transition" suggests that these transformative processes are closely linked and should complement each other (Muench et al., 2022).In this context, a twin transition might be achieved through the coupling of green and digital technologies, with the goal that digital applications can facilitate and accelerate GT, whereas the green transition can, in turn, shape the priorities and objectives of digital technological innovation.Existing research on the twin transition primarily focuses on the relationship, similarities and potentials of green and digital technologies, often from a quantitative perspective by investigating twin transition processes through patent data analysis.These studies indicate that many digital technologies can combine to constitute the development of GT at the regional level (Kopka and Grashof, 2022;Cicerone et al., 2022;Montresor and Vezzani, 2023).Furthermore, the research highlights numerous potentials of digital technologies for sustainability, with general-purpose technologies, particularly AI, emerging as the most transformative, holding the greatest potential to drive the digital transformation of the economy and offering several sustainability applications (Cockburn et al., 2019;Mouthaan et al., 2023).
However, two major research gaps remain, which are addressed in this paper.Firstly, there is a gap in how these technologies can be systematically combined to unlock their full potential and develop digital green applications.Previous research has primarily focused on how regional knowledge of green and digital technologies mutually influence each other and has not yet investigated innovation modes within company-level internal innovation processes or collaborations (Montresor and Quatraro, 2020;Santoalha et al., 2021;Montresor and Vezzani, 2023).Secondly, the role of the twin transition in local innovation agglomerations such as clusters or industrial districts is still a relatively under-explored perspective.Recent research has shed light on how clusters undergo digital or green transition processes.Götz and Jankowska (2017) already suggested that clusters might facilitate digital transformation, requiring a certain level of expertise in the field, despite the common assumption that digital technology contradicts local and regional aspects due to its global interconnected nature.Additionally, Bettiol et al. (2021) demonstrated that companies in industrial districts tend to invest more in technologies related to the fourth industrial revolution.Herv as-Oliver (2021) also examined Industry 4.0 adoption in industrial districts and showed that collaborations are essential for digital transformation.Conversely, the sustainability transformation through clusters is also gaining attention (Lis and Mackiewicz, 2023).Although research on the green and digital transition of clusters is growing, there is still a lack of knowledge on how cluster organizations are systematically used to combine digital and green technologies, thus triggering twin transition processes.Overall, twin transition research has primarily focused on Western economies, with research on twin transition dynamics in emerging economies still being relatively new.This is surprising given the potential of emerging economic systems, such as China, to adapt to new technologies.On the one hand, this is due to China's comprehensive promotion of AI and its commitment to both the sustainability transition through GT and the pursuit of twin transition ideas (Filiou et al., 2023).On the other hand, it is related to the potential of the fastacting state-led innovation system, which grants local innovation actors experimental freedom (Heilmann et al., 2013).These conditions show the potential for rapid innovation development in new technology domains, making China a crucial study area.
In this paper, the two research gaps are addressed by examining the twin transition in China, with a specific focus on AI technology used for GT, e.g. machine learning models regulating and efficiently managing energy distribution from renewable energies.The paper particularly focuses on the combined utilization of these technologies, as they can be classified as radical twin innovations and hold the greatest potential for a twin transition (Mäkitie et al., 2023).Furthermore, it is investigated whether and how companies internally develop these twin innovations and how collaborative development through state-led cluster organizations is promoted and managed.Specifically, this matter is examined from the perspective of German multinational enterprises (MNEs) operating an R&D centre in China.In doing so, insights are gained from the angle of foreign multinationals, which have been instrumental in China's innovation system in the past decades.However, this role has become increasingly uncertain due to geopolitical shifts since the COVID-19 pandemic and China's shift in innovation policy that affects the integration of MNEs in clusters.Hence, the paper aims to emphasize the role of multinationals in twin transition technology domains in China.The following two research questions were formulated to address the two research gaps from the perspective of MNEs in China: RQ1.How do foreign multinationals develop AI, GT and twin innovations (AI/GT) in China?RQ2.How are innovation processes combining AI/GT organized and administered in clusters, and how are multinationals involved in the innovation processes and integrated into Chinese innovation systems?
For the empirical part of the paper, 11 expert interviews were conducted with executives from German multinationals in China.The interview data were analysed using thematic qualitative text analysis.The remainder of the paper is structured as follows: Section 2 delves into background literature concerning twin transition perspectives in China, the organization of innovation and the role of multinationals.Section 3 outlines the methodological approach, explaining data collection, analysis and evaluation.The results are presented in Section 4, and the paper concludes with a discussion and conclusion in Sections 5 and 6.

Background literature 2.1 Green, digital and twin innovation in China
In Western nations, various policy programs have been launched in recent years to exploit and systematically promote certain potentials of a twin transition.For example, the Joint Research Center of the European Commission summarizes the key requirements for a successful twin transition in the EU (Muench et al., 2022).However, research on twin transition is still relatively new and not yet comprehensively understood.For now, there are only a few studies on the impact, effects and potentials of a twin transition, and there is a current focus on Western economies in twin transition research.Cicerone et al. (2022) observe that AI knowledge positively influences green-tech specialization in EU-28 regions, although certain constraints need to be considered, such as the prerequisite of existing green knowledge within regions.Kopka and Grashof (2022) presented similar findings and examined the link between AI and sustainability in German regions.They demonstrate that regional industrial structure needs to be understood to establish the link between AI and sustainability.Bianchini et al. (2023) examined the impact of digital and green technologies on greenhouse gas emissions in European regions.They find that while digital technologies can contribute to negative environmental impacts, linking them with existing green technologies can help reduce these impacts.Benedetti et al. (2023) discussed European features of a twin transition by investigating the impact of digitalization on energy efficiency and found a positive impact of digitalization across EU member states.Additionally, Almansour (2022) explored the twin transition from a qualitative perspective indicating that digital features influence the consumer adoption of electric vehicles.Scholars also show that the combination of digital and green technologies at the firm level can positively contribute to the twin transition, for example by increasing green competitive advantage (Rehman et al., 2023), or that urban firms can better exploit the potential of digital technologies compared to rural firms (Cattani et al., 2023).Furthermore, Collini and Hausemer (2023) took an agency-based approach to understanding twin transition pathways.They conceptualize that systemic change agents, such as clusters, influence twin transition pathways.
Overall, twin transition research in Western nations indicates that the combination of digital and green technologies at the regional, local and firm levels has great potential for harnessing twin innovations.Although these research findings demonstrate the necessity of a local perspective in comprehensively understanding the twin transition in industrialized countries, the regional and local factors contributing significantly to the twin transition in emerging economies remain largely unknown.To understand these local features of the twin transition, China makes an excellent study area, shaping the global innovation landscape in both digital and green technologies and increasingly affecting the digital and green transformation worldwide.
China is establishing a comprehensive AI strategy focusing on development and implementation across several industries and is thus building on AI as a pivotal factor for digital transformation (Pan, 2016;Wu et al., 2020;Yu and Zhang, 2021).In the Chinese policy context, AI is defined from three perspectives: the basic perspective (infrastructure and hardware), the technological perspective (e.g. machine learning) and the application perspective (e.g.smart city).This paper deliberately concentrates on AI technology that can contribute to sustainability or facilitate the development and improvement of GT.Consequently, technological and application perspectives of AI are considered, and this approach is also supported by AI definitions in the economics literature (Agrawal et al., 2019).Apart from the AI strategy, China has become a leading innovation nation in several GT domains in the past years (Huang and Lema, 2021).Due to massive investments in GT to address pollution and environmental crises, there is a growing amount of scholarly interest in how GT emerged and diffused in China (Horbach, 2014;Losacker and Liefner, 2020b).In this paper, the terms GT, eco-innovation and environmental technology are treated as synonyms.Therefore, definitions provided by Kemp et al. (2019) and Barbieri et al. (2020) are used, which consider GT as new or improved products or practices that lower environmental impacts or mitigate or reverse the negative effects of human action on the environment.
Research on GT and AI in China appears to be extensive; however, the systematic combination of these technologies remains largely obscure in the scholarly literature, although initial studies on twin transition in China are emerging.For instance, Zhang and Du (2023) showed how the digital economy in Chinese cities reduces urban carbon emissions, highlighting regional variations in the potential of digital technology for green applications.Gao et al. (2023) delved into the role of big data in green innovation and demonstrated its positive effects.Furthermore, Ahmad et al. (2023) asserted that China's technological innovation fosters sustainable developmenta view shared by Chen et al. (2023), who determined that fiscal science and technology expenditure can lower CO 2 emissions, albeit with regional disparities.Li et al. (2023) discussed tangible applications of machine learning for urban sustainability in a review paper.The comprehensive political AI strategy also aligns CR with sustainability objectives.Xu et al. (2023) demonstrated that China's smart city policy positively influences green technological innovation.Furthermore, Filiou et al. (2023) explored the joint impacts of green and digital policies, analysing their influence on the emergence of eco-innovation.They assert that city-based AI policies significantly contribute to the increase in green patents.Collectively, a number of studies in recent years have examined the relationship between green and digital technologies in China.Nonetheless, a distinct perspective on innovation processes from a spatial standpoint remains notably absent.

Organization of innovation and the role of multinational enterprises in Chinese innovation systems
The innovation development in China is mainly characterized by a state-led innovation system that combines top-down processes with bottom-up dynamics (Heilmann et al., 2013;Lauer and Liefner, 2019;Fischer et al., 2021).Therefore, China's policy aims to establish cluster-based organizations of innovation actors, which facilitate innovation and are guided by authorities.This organization of innovation processes has historically revolved around pilot zones, which offer innovation actors experimental freedoms and are designed to initiate transformation and technological change in specific industries.Prominent examples include technology parks and science cities, as well as special economic zones (SEZ), which have been instrumental for attracting foreign companies' investment in the past (Teng et al., 2020;Zeng et al., 2011).Through this approach to inducing innovation, local and regional authorities can specifically address the economically heterogeneous nature of China and stimulate transformation processes in regional innovation systems (Xue et al., 2021;Liefner et al., 2021).This paper mainly refers to cluster organizations, which describe the state-led organization of innovation processes in clusters and industrial districts.The clusters are primarily created through pilot and demonstration zones, which establish networks between participating actors.In recent years, China extended these cluster organizations for developing technological solutions for green or digital domains, e.g.eco-cities for GT and sustainability applications (Chang et al., 2016;Wu et al., 2023), and AI pilot zones for AI applications (Arenal et al., 2020;Yang and Huang, 2022).Although certain processes and structures (especially in eco-cities) have already been studied, research on AI clusters is still in its initial stage and has not yet been able to show exactly how innovation processes take place and how AI/GT applications are developed.
In this context, it is also unclear what role foreign MNEs play in the innovation process in twin technologies.MNEs and foreign direct investment (FDI) have played an important role in these Chinese innovation systems.Starting in SEZs, regions attempted to spatially cluster FDI and attract MNEs resulting in rapid economic growth and the establishment of wellfunctioning innovation systems.Hereby, MNEs have not only acted as conduits for technology transfer and knowledge spillover, importing managerial expertise, advanced technologies and best practices but have also contributed to China's technological capabilities by driving industry advancement.The establishment of R&D centres by MNEs in China has adapted products to the local market and initiated technological progress and innovation.Therefore, MNEs have been crucial in fostering innovation through knowledge diffusion and technology upgrading (Blomstrom and Kokko, 1998;Liefner et al., 2013;Hayter and Han, 1998).
Many MNEs are essential components in existing innovation capacities that have been in place for a long time and are also involved in organizations and innovation dynamics, especially in several technology domains (Du and Krusekopf, 2023).However, because the Xi Government took office, there has been a strategic realignment of the national innovation strategy (Fischer et al., 2021).Starting with the "Made in China 2025" strategy, the country is Foreign MNEs in China's twin transition increasingly relying on its own innovation activities and promoting indigenous innovations (Losacker and Liefner, 2020a).The involvement of foreign MNEs in new technology domains, in which China aims to establish itself as a leader (especially in AI and GT), is becoming increasingly uncertain.Research on this topic is still relatively scarce, particularly in the area of twin transition technology.In this context, it seems important to understand the international linkages and entanglements in the organization of innovation processes.

Data collection and analysis
To answer the research questions, this paper uses a case study approach to examine the twin transition in China (Yin, 2017).The paper studies both internal innovation processes within the companies and the organization of innovation processes in AI/GT led by state actors.In doing so, the matter is examined from the perspective of German multinationals in China that are involved in innovation development, either by having an R&D centre or being well-versed in the field.The contact was initiated with the support of business representatives and committees that specifically approached various German companies with an R&D presence in China.The prerequisite for these companies was that they possessed expertise in either AI, GT or both.The interviewees were required to be knowledgeable about the innovation processes within the company and capable of assessing organizational structures and collaborations in China.The interview participants consist of 10 companies from several industries with an R&D centre in China and one management consulting company that is engaged in and advises on digital and green innovation projects.The positions of the participants are all top-level executives.The companies are predominantly major listed corporations that possess extensive global market shares in their respective industries and have contributed a large volume of investment to China.For this study, German companies were selected as the research object because they offer two advantages: firstly, German companies are among the most active FDI drivers, especially in China, where they have been an established part of the economy and innovation development for decades, and secondly, the features of German multinational firms' participation in FDI activities do not differ significantly from those of other developed countries.German MNEs can therefore provide new information on how exactly innovation processes take place in China, and they can also serve as a model for investments by other industrialized countries in China (Chen and Reger, 2006).
To carry out the exploratory approach, semi-structured interviews were conducted using interview guides (Meuser and Nagel, 2009).The interviews took place from February to June 2023 using video calls.Subsequently, the interviews were transcribed and anonymized.The research approach and the three sections of the interview guide are illustrated in Figure 1.Various descriptive data of the interview sample are summarized in Table 1.
The interview data were analysed using a thematic qualitative text analysis, as outlined by Kuckartz (2014).Based on the research questions and theoretical considerations, the main Research approach and sections of the interview guide CR categories were formed through a deductive approach, which is divided into development, organization and participation.Building on this, an inductive approach was used to form subcategories on the material, thus identifying specific approaches of different companies.This approach ensures that both the theoretical framework and the exploratory content provided by the experts are included in the analysis.The data analysis was conducted with the assistance of the qualitative data analysis tool MAXQDA.

Artificial intelligence and green technology innovation development of German multinational enterprises
The approaches of German MNEs with R&D centres in China to develop AI innovations for environmental protection and sustainability are highly heterogeneous.Across all companies, there was a consensus on the importance of GT and how AI and other digital technologies can contribute to achieving the objective of becoming carbon neutral.However, the implementation of these twin innovations is still in an early stage.Therefore, while most of the companies interviewed have engaged with both technology fields, they have not yet developed comprehensive integrated solutions.In fact, the companies interviewed were either more familiar with GT, researching sustainable alternatives to comply with environmental regulations in China and offer more sustainable alternatives in the market, or were more acquainted with digital technologies, having closer connections to digital solutions, products or processes and thus having previous experience with AI technology.The interviews reveal that companies with more experience in environmental technology development are more actively seeking ways to apply AI to GT.In the interviews, these were mainly self-learning applications for increasing energy efficiency in core products (I9), complex process flows in material extraction and allocation (I3, I7) or waste management coordination (I1, I4): We use AI explicitly for our product development and optimization, as it helps us to operate the energy processes within our applications (I9).
Contrarily, companies from the digital sector are significantly investing in AI research and its implementation in corporate processes.Nevertheless, it becomes evident that the explicit Foreign MNEs in China's twin transition exploration of AI/GT, i.e. active research aimed at connecting these technologies, is not of utmost importance.It tends to be more of a positive side-effect that often accompanies these efforts, but is not the primary motivation: Sustainability is in our identity; however, our aim is not to develop use cases of AI for environmental technology, it is more of a byproduct of AI which often comes along due to positive effects of the technology (I6).
For us, AI is integral, which means that we do not look top-down for sustainable application strategies, but apply it everywhere and thus naturally also within the scope of our environmental technologies (I2).
In addition to these diverse approaches to AI/GT, the interviews conducted reveal that the two technologies are perceived as spatially distinct.According to the interviewees, innovation development in GT primarily occurs in localized and streamlined manners, while innovation development in AI originates from a national level in China.From the perspective of some companies, regional factors are particularly responsible for funding and development of GT: The promotion of AI strongly originates from the central government at the national level and is then adopted or expanded by regions or local governments.[. ..]In the sustainability and GT domain, this is much more locally nuanced.For example, in Northern China, waste recycling aligns with agriculture; they have a lot of straw and are considering how to transform it into chemicals and utilize it intelligently (I3).

Organization of innovation and participation of German multinational enterprises
Chinese organization of innovation processes: The interviews show that new cluster organizations arise from the specific AI pilot and demonstration zone approach.These are managed and operated differently, and involve different innovation actors to former hightech parks and science cities with a new focus on green and digital technologies.The clusters consist of different industrial districts, each with a specific thematic focus determined by the regional government.There are multiple levels to these clusters, and a network is actively built between the companies and other actors, controlled and monitored by state-owned enterprises (SOEs).Moreover, being included in such a cluster organization brings numerous incentives.However, the orientation here also depends on regional factors.For instance, a local company can significantly influence the strategic orientation of the regional government: The parks, as part of the pilot zones, are organized to provide very comprehensive assistance (talent, infrastructure, service) to all companies and research institutions [. ..], the management of the parks is controlled or directed by the regional or municipal governments through state-owned companies, [. ..] we are in close contact with the park management, they help us to solve any issue (I5).
The role of the local and regional government is particularly significant in the case of AI clusters.The government plays a steering role by setting clear project objectives that affect the companies supported, which must fulfil these requirements no matter what.The government then takes on a supportive role, giving companies space to operate.There is consensus among AI-oriented companies regarding the future role of data, which is an essential foundation for the self-improvement capability and functionality of AI.Through monitoring tasks, the local and regional authorities have access to this data and can use or provide knowledge in projects.The new data protection laws in China require that this data remains in the country and allow local and regional governments to access it by taking on monitoring and review tasks.Through this access, the data and knowledge can be used and provided in cross-cutting projects, resulting in a significant advantage, especially when data is seen as a production factor for AI (Cockburn et al., 2019): Regional authorities set a target and provide massive support for companies to achieve this target, how this is done doesn't really matter, but often the path leads to AI and often AI helps to be more sustainable (I7).
There are several laws in China that prohibit the transport of data out of China.[. ..] the innovation processes are kept in the country by monitoring tasks of the regional governments; this allows regional and local governments to review the data.[. ..] so data can actually be seen as a production factor and this means that China has a massive advantage in terms of the access to data and the possibilities to train AI applications (I2).
Through the interviews, it becomes clear that the role of the regional government is also crucial for the combination of AI/GT, as they often set targets for innovation projects within the organizational structures (clusters and networks).These projects are encouraged by high funding amounts and state support for process flows, prompting them to leverage their respective entrepreneurial capabilities and potentials.As a result, AI technologies are much more likely to be used for GT or sustainability, as different actors from different backgrounds collaborate on a larger scale, with the regional government providing the framework: We have been part of an innovation project where we contributed GT and a large Chinese software company contributed AI applications which improved our product.[. ..] in the project the regional government brought us all together and explained what they wanted from us, we then collaborated with the other companies to develop an inter-city waste disposal system which was based on a self-improving AI application and therefore helped us to be much more efficient since it could coordinate and redirect the waste disposal within the city (I1).
Participation of German MNEs: The involvement of German multinationals in clusters and their inclusion in the innovation system within the technology development of AI/GT is highly diverse.The situation of German companies can be described from three directions.Firstly, companies that are important for the innovation system and developments in China have access to and are actively included in these cluster organizations.The companies sometimes receive state subsidies, including for the development of AI/GT.They collaborate with local or regional authorities and cooperate closely with Chinese companies, research institutes, startups or universities to develop products or processes.Furthermore, they are involved in large-scale innovation projects that bring together various innovation actors.When collaborating in the field of AI/GT in large-scale projects, these companies contribute significantly, although large Chinese software companies mostly undertake AI development: We collaborate with other companies, but in the field of AI implementation mainly or actually only with the Chinese tech giants, they have the expertise in the field and it is only possible to work with them when we want to work on smart city projects which are led by the government.
Secondly, autonomous companies that exclusively conduct research in their fields in China serve the local and regional markets.They do not wish to be involved in the clusters and are not included.These companies have primarily come to China because the market for their technologies is particularly attractive, and they conduct research that serves the local market.However, they continue to pursue global innovation Foreign MNEs in China's twin transition processes within the company and thus do not want to be involved in regional innovation processes: We don't want to work closely with other companies or in these state clusters, we want to serve the local market first and foremost and do research for the market by localizing here, to do this we get ideas from academia or startups into the companywith the goal of outside-in (I2).
Thirdly, companies that would like to benefit from the innovation system but cannot access the cluster organizations are systematically excluded from these local innovation processes.These companies feel systematically marginalized and would like to collaborate with other institutions to bring together AI/GT, but they lack connections to decision-makers and are not actively included in the network: We would like to participate more in digitization funding programs, but we are excluded as a foreign company, we don't have access to the clusters or local funding sources by the regional government (I8).

Discussion
The results already show that multinationals more focused on GT are more inclined to explore AI applications for GT innovations.Conversely, multinationals more familiar with AI are not necessarily seeking GT applications for their AI advancements.Although this outcome was not entirely anticipated, given the AI/GT innovation potentials of companies within China and research indicating the interconnectedness of these processes, particularly in the Chinese context (Wang et al., 2023;Gao et al., 2023), it is not entirely unexpected.Some of the companies aligned with GT mentioned that while they aim to apply AI within their organizations for innovation processes, they might not yet have reached a stage where AI is comprehensively integrated and used for operations.Furthermore, it is intriguing that companies more oriented towards AI specifically come to China to explore the digital market and seem to largely overlook the potential applications of GT within their AI endeavours, even if not every company is willing and able to develop twin innovations.Even though AI/GT twin innovations are still in their early stages, several companies are already systematically researching internal applications.However, these twin innovations are primarily implemented through state-led collaborations within innovation projects.These large-scale projects are initiated by regional and local governments, establishing a framework of goals and assembling a network of companies, startups and research institutions from various domains to jointly develop solutions.This approach enables faster and more effective utilization of both AI and GT in innovations.This aspect has been less emphasized in existing literature, yet it becomes clear that regional governments play a pivotal role, particularly in driving the twin transition at the regional level.Thus, the modes of innovation in the Chinese twin transition rely more on collaboration than intra-company innovation processes.
Furthermore, the findings indicate that the role of local and regional governments is not only crucial for initiating twin innovation but also for organizing the clusters, networks and innovation agglomerations of actors.The cluster organizations emerging from pilot and demonstration zones are primarily established by the local and regional authorities.The management and control of cluster organizations are then handled by SOEs.Moreover, it has become apparent that the role of data, especially as a production factor for AI applications, is becoming increasingly vital.While this is already a consensus in AI research (Roberts et al., 2022;Cockburn et al., 2019), the interview observations provide a novel perspective.Due to the active involvement of the government and SOEs, data is often exchanged with authorities or SOEs within organizational structures, granting them considerable data sovereignty.This raises questions about data handling and utilization that could not be answered within the scope of this study.
Finally, the paper demonstrates that the role of German companies is multifaceted.German multinational engagements fall into three types: integrated, autonomous and excluded.This result builds on the previous understanding that particularly for the combination of AI/GT, it is crucial to be integrated into the cluster organizations.Once access to networks and clusters is established, and contributions in specific technology domains are possible, advanced innovation projects can be initiated, often led by local or regional authorities involving several interdisciplinary actors.If not part of these network structures, decoupling processes seem to take place.This pattern is also consistent with the revisited Uppsala internationalization process model by Johanson and Vahlne (2009).According to this model, the liability of outsidership leads to systematic disadvantages and uncertainties for companies arising from network structures.Moreover, it appears that certain technology fields remain predominantly reserved for Chinese companies, even when foreign multinationals participate in larger innovation projects and networks.In such cases, large Chinese software companies often take on the tasks of developing and applying AI models.This development can be discussed within the framework of technology sovereignty.China's mission-oriented innovation policy aims to develop technologies according to its goals, designating AI (partially also GT) as critical to future economic competitiveness (Edler et al., 2023).This may explain why foreign multinationals are excluded from the innovation processes in certain domains.
The companies also differ in their focus on twin innovations.Integrated companies are incorporated into cluster organizations and thereby contribute to the development of local twin innovations, which arise within the framework of innovation projects.They are deeply integrated into existing innovation processes and have strong connections with various innovation actors from different domains, as well as local authorities.Autonomous companies rely on internal innovation processes and partially develop internal AI/GT solutions.They are not very engaged in knowledge exchange and primarily aim to bring in external knowledge through unidirectional innovation cooperations that involve universities or startups.Excluded companies hardly develop AI/GT applications but rather focus on one technology domain.On the one hand, this is due to the limited R&D exchange with other innovation actors and the lack of integration into existing Chinese innovation systems.On the other hand, it is also due to the absence of other global innovation activities and individual goals, which mainly differentiate them from autonomous companies.Figure 2 visualizes the connections between the type of foreign MNE and various collaborative innovation actors.Table 2 illustrates the types of foreign multinationals in China and reveals the role they take within Chinese cluster organizations and their collaborative actors.The findings suggest that integration into cluster organizations can indeed facilitate the twin transition.The role of foreign companies in China is thus greatly dependent on their integration into the Chinese innovation system, especially in the domains of green and digital technologies.Therefore, foreign companies in China should consider the role they play within the Chinese innovation system and the implications this has on their twin innovation processes.Local circumstances can significantly influence the role within their technology fields as well as the integration into cluster organizations.
The interviews also revealed that these different approaches are influenced by various factors.Formal and informal institutions, as well as informal connections to regional authorities or other key actors, play a role in the participation in AI clusters or other cooperation endeavours.Nonetheless, decoupling processes can be observed in the interviews.On the one hand, decoupling processes occur through the systematic exclusion of German multinationals that seek involvement in the innovation processes of new twin technology domains.On the other hand, decoupling processes also involve German companies contemplating diversification of their economic activities in China due to geopolitical situations.
It is important to acknowledge the limitations of this work.Firstly, it is crucial to note that the study primarily examined MNEs headquartered in Germany.These companies may be subject to formal or informal differences at the national level that distinguish them from MNEs from other countries.Nevertheless, German companies and their international operating strategies exhibit characteristics that are rather typical of investments from other industrialized nations.Furthermore, it is worth noting that the number of expert interviews seems relatively modest.However, the analysis of these interviews revealed that theoretical saturation was reached, which underlines the richness of insights obtained.This saturation is attributed to the study's deliberate focus on German MNEs with R&D centres in China, which provides a highly specific perspective that enhances the depth and relevance of the findings.
Additionally, the field in which German MNEs operate in China is also very much shaped by geopolitical tensions and developments between the EU and China.Although FDI often remains very long-term, short-term developments and thus the participation of foreign multinationals in China are partly dependent on the current political situation.Future research could dive deeper into the innovation processes of cluster organizations in the twin transition through AI/GT and compare the role of foreign multinationals with indigenous companies.

Conclusion
This paper has investigated the development and organization of the twin transition in China through interviews with German multinationals.To do so, two research questions addressed the research gaps identified.The findings related to the first research question, "How do foreign multinationals develop AI, GT and twin innovations (AI/GT) in China?" indicate that internal AI/GT development within companies is more often carried out by companies closely aligned with GT in their core business.Across companies, there are innovation projects guided by local or regional authorities, which involve various stakeholders and lead to the development of twin innovations.Regarding the second research question, "How are innovation processes combining AI/GT organized and administered in clusters, and how are multinationals involved in the innovation processes and integrated into Chinese innovation systems?", the organization continues to function through China-specific cluster organizations, where the role of local and regional government gains significance due to new data processes.Additionally, various involvements of German multinationals in twin innovation processes can be observed, with the companies either being integrated, remaining autonomous or being excluded.Integrated companies contribute to the development of twin innovation in crosscompany projects, even if the task of AI development remains primarily with large Chinese software companies.Autonomous companies partially develop AI/GT innovations on their own and stay out of collaborative innovation.Initial decoupling processes in twin innovations can be observed through excluded companies, which mostly stay out of AI/GT innovation development.Foreign companies should be aware of their role in the Chinese innovation system (integrated, autonomous and excluded) and what this means for their innovation processes.
Companies that want to participate in twin transition innovations in China in the future must be aware of the local characteristics.The findings offer new insights into achieving a twin transition through twin innovations (AI/GT applications) and can provide context for the prospective participation of foreign multinationals in these innovation processes.Consequently, the paper contributes valuable insights into the development and organization of innovation processes within the twin transition in an emerging economy, demonstrating the importance of being involved in local cluster organizations.Organization of AI/GT innovation processes (6) How are twin innovation processes (AI/GT) organized and directed by the government (e.g.political support, incentives and state-led innovation projects)?(7) How is your company involved in AI or GT cluster organizations (AI, GT clusters and networks) and how are the clusters organized (what processes take place)?(8) How does your company collaborate with other innovation actors (companies, universities, startups and government) to develop AI, GT and AI/GT innovations (involvement in specific cluster organizations or projects)?( 9) What do you see as the advantages and disadvantages of the cluster organizations in developing twin innovations?Participation of German multinationals in AI/GT innovation processes (10) What are the differences between German and Chinese companies in innovation development?(11) What challenges do you see for your company in the field of AI and GT in China in the future?(12) What kind of support for AI/GT innovations and participation in innovation projects would be desirable for your company in China?
Closing question Would you like to add anything else to the interview?
