Abstract
Purpose
Uncertainty is inevitable in real-world engineering optimization. With an outer-inner optimization structure, most previous robust optimization (RO) approaches under interval uncertainty can become computationally intractable because the inner level must perform robust evaluation for each design alternative delivered from the outer level. This paper aims to propose an on-line Kriging metamodel-assisted variable adjustment robust optimization (OLK-VARO) to ease the computational burden of previous VARO approach.
Design/methodology/approach
In OLK-VARO, Kriging metamodels are constructed for replacing robust evaluations of the design alternative delivered from the outer level, reducing the nested optimization structure of previous VARO approach into a single loop optimization structure. An on-line updating mechanism is introduced in OLK-VARO to exploit the obtained data from previous iterations.
Findings
One nonlinear numerical example and two engineering cases have been used to demonstrate the applicability and efficiency of the proposed OLK-VARO approach. Results illustrate that OLK-VARO is able to obtain comparable robust optimums as to that obtained by previous VARO, while at the same time significantly reducing computational cost.
Practical implications
The proposed approach exhibits great capability for practical engineering design optimization problems under interval uncertainty.
Originality/value
The main contribution of this paper lies in the following: an OLK-VARO approach under interval uncertainty is proposed, which can significantly ease the computational burden of previous VARO approach.

Abstract
Purpose
This paper identifies the development of and gaps in knowledge in various management disciplines, including international marketing in relation to political ties in emerging markets, based on a systematic review of the related literature. The paper develops a synthesized integrative framework and provides a research agenda and pathways for future research.
Design/methodology/approach
The study adopts the systematic literature review protocol to investigate the ways in which political ties have been examined in the management literature in various disciplines, such as international business, marketing, entrepreneurship, strategy, innovation, and organization. In total, 114 articles published in peer-reviewed journals from 2000 to 2022 were analyzed.
Findings
The authors believe that studying the impact of political ties on firm outcomes is timely and important as interest in this area of research is growing rapidly. The review reveals that the diverse conceptual and methodological approaches adopted in different management disciplines have resulted in inconclusive and mixed findings on the relationship between political ties and performance.
Originality/value
This is one of the few systematic literature reviews of political ties and firm performance in emerging markets. The authors clarify some of the ambiguities around the subject and offer a path forward for developing current understanding and insights. The study also highlights the major perspectives in management and clarify the similarities and differences in the conceptualization of political ties. In addition, the authors develop an integrative framework of the political ties–performance link in emerging markets.

Abstract
As part of the mobility of global talent, returnee entrepreneurs from emerging markets with advance technology are particularly challenged by the increasing geopolitical tension. Returnee entrepreneurs have a stronger reliance on the political relationship when establishing successful business at the home countries. Yet this connection with home-country political actors can negatively affect their technology competence obtained from the host countries during geopolitical uncertainty and turbulence. We empirically investigate the challenges that technology-advanced returnee entrepreneurs encountered in the home market from the changes occurred while they were away, as well as the needs to obtain critical resource and gain market entry for adapting the advance technology possessed from aboard. Our aim, nevertheless, is to expand the discussion of the returnee entrepreneurs in the context of current world where unpredictable geopolitical tensions can jeopardize the success of their business. Our study contributes a nuanced understanding of the key factor that driving business success may turn to a trap that constrains returnee entrepreneurship, and accordingly proposes a future research agenda for returnee entrepreneurship and international human mobility in general.

Abstract
Purpose
Although the role of returnees is critical to firm innovation, the literature offers inconsistent findings regarding returnees' effect on firms' innovation performance. To reconcile this issue, the authors argue that taking the types of innovation into account – i.e. technical innovation and commercial innovation – is necessary. Thus, the purpose of this study is to examine how firms led by returnees affect the relationship between research and development (R&D) input and above two types of innovation output, as well as the contingent role of political connections (PCs) and venture capital funding (VC funding).
Design/methodology/approach
This study empirically tested the hypotheses using a dataset of 54,617 firm-year observations for 18,475 Chinese firms in Zhongguancun Science Park (ZSP) from 2009 to 2014.
Findings
The results show that the positive effect of R&D input on technical innovation performance (TIP) is reinforced when firms are led by returnees, while the positive effect of R&D input on commercial innovation performance (CIP) is weakened when firms are led by returnees compared with those firms led by the local counterparts. The findings further show that returnee firms' positive effect on the relationship between R&D input and technical innovation performance is more salient for firms with more PCs but weakened for those with more VC funding.
Originality/value
This study enriches the research on returnee firms' advantages and disadvantages in transforming R&D input into innovation performance, and the findings highlight that firms led by returnees can increase R&D efficiency of technical innovation, but reduce R&D efficiency of commercial innovation. Moreover, this study offers a contingent view of political and economic stakeholders' roles in returnee firms' innovation, by revealing PCs help returnee firms to enhance R&D efficiency in technological innovation, while venture capital can hamper such R&D efficiency.

Abstract
Purpose
Fresh product loss rates in supply chain operations are particularly high due to the nature of perishable products. The purpose of this paper is to maximize profit through the contract between retailer and supplier. The optimized prices for the retailer and the supplier, taking the fresh-keeping effort into consideration, are derived.
Design/methodology/approach
To address this issue, the authors consider a two-echelon supply chain consisting of a retailer and a supplier (i.e. wholesaler) for two scenarios: centralized and decentralized decision making. The authors start from investigating the optimal decision in the centralized supply chain and then comparing the results with those of the decentralized decision. Meanwhile, a fresh-keeping cost-sharing contract and a fresh-keeping cost- and revenue-sharing contract are designed. Numerical examples are provided, and managerial insights are discussed at the end.
Findings
The results show that the centralized decision is more profitable than the decentralized decision; a fresh product supply chain (FPSC) can only be coordinated through a fresh-keeping cost- and revenue-sharing contract; the optimal retail price, wholesale price and fresh-keeping effort can all be achieved; and the profit of a FPSC is positively related to consumers’ sensitivity to freshness and negatively correlated with their sensitivity to price.
Research limitations/implications
This research is based on the assumption that demand is relatively stable. It has not addressed when demand is stochastic.
Practical implications
The findings would be useful for managers in fresh food sector in terms of how to deal with suppliers in order to maximize total profit while also provide freshest food to the customers.
Originality/value
Few studies have considered fresh-keeping effort as a decision variable in the modelling of supply chain. In this paper, a mathematical model for the fresh-keeping effort and for price decisions in a supply chain is developed. In particular, fresh-keeping cost-sharing contract and revenue-sharing contract are examined simultaneously in the study of the supply chain coordination problem.

Abstract
Purpose
The purpose of this study is to examine the moderating effect of two types of external funds in terms of loan and government subsidy on the relationship between R&D investment and firms' innovation performance in emerging markets, as well as the contingent role of firm leader's international experience associated with the effects of loan and government subsidy.
Design/methodology/approach
The authors tested the hypotheses using a longitudinal dataset of 716 high-tech firms of Zhongguancun Science Park (ZSP) in China during 2008–2014, covering detailed information on the operations, financial situation and R&D activities, patents, etc. The authors finally identified an unbalanced panel of 2,430 firm-year observations. Considering the dependent variable is the countable data and non-negative values, the negative binomial regression with fixed effects was adopted to test the hypotheses.
Findings
The results show that the more loans or government subsidies the firm receives, the weaker the positive effect of R&D investment on firms' innovation performance in emerging markets. Furthermore, the findings reveal that firm leaders' international experience can mitigate the negative moderating effect of government subsidies, but strengthen the negative moderating effect of loans.
Originality/value
The study provides new insights into how loans and government subsidies as external funds influence the effectiveness of R&D in enhancing innovation performance, and the findings highlight the fact that more external funds can reduce firm R&D efficiency. Moreover, the authors also enrich the resource orchestration theory by revealing the critical role of firm leaders' international experience in the decision-making of resource configuration to mitigate the inefficiency of high subsidies in emerging markets.

Abstract
Purpose
Building on the resource- and knowledge-based views, this paper aims to explore how coopetition affects radical innovation and the roles of knowledge structure and external knowledge integration in the relationship between coopetition and radical innovation.
Design/methodology/approach
This study proposes a research model to examine the mediating role of external knowledge integration on the coopetition-radical innovation link, where the mediation is moderated by the firm’s knowledge structure (including component knowledge and architectural knowledge). The authors use regression and bootstrapping to test the proposed model with survey data from 241 Chinese technology firms.
Findings
This study finds that coopetition positively affects radical innovation and the effect is fully mediated by external knowledge integration. Additionally, component knowledge negatively moderates the coopetition-external knowledge integration link and architectural knowledge positively moderates this relationship. Further, the mediating effect of external knowledge integration is also moderated by component knowledge and architectural knowledge.
Practical implications
Firms should engage in coopetition to promote radical innovation. Further, it is necessary for firms to appropriately manage coopetition according to their internal knowledge structure.
Originality/value
This study explains why scholars have different ideas about the relationship between coopetition and radical innovation by exploring the mediating role of external knowledge integration and the moderating effect of knowledge structure. Firms possess increased possibilities for knowledge leakage and partner opportunism with high levels of component knowledge, which will reduce the positive effect coopetition on external knowledge integration; thus, they are less likely to realize radical innovation. Instead, firms possess increased opportunities for resource sharing with high levels of architectural knowledge, thus improving the positive effect coopetition on external knowledge integration and they are more likely to achieve radical innovation.

Abstract
Purpose
The purpose of this paper was to map the safety management research of construction industry by scientometric analysis, which can predict important highlights and future research directions of safety management research in the construction industry. As an important issue in the construction industry, safety management issues have been researched from different perspectives. Although previous studies make knowledge contributions to the safety management research of construction industry, there are still huge obstacles to distinguish the comprehensive knowledge map of safety management research in the construction industry.
Design/methodology/approach
This study applies three scientometric analysis methods, collaboration network analysis, co-occurrence network analysis and cocitation network analysis, to the safety management research of construction industry. 5,406 articles were retrieved from the core collection database of the Web of Science. CiteSpace was used for constructing a comprehensive analysis framework to analyze and visualize the safety management research of construction industry. According to integrating the analysis results, a knowledge map for the safety management research of construction industry can be constructed.
Findings
The analysis results revealed the academic communities, key research topics and knowledge body of safety management research in the construction industry. The evolution paths of safety management research in the construction industry were divided into three development stages: “construction safety management”, “multi-objective safety management” and “comprehensive safety management”. Five research directions were predicted on the future safety management research of construction industry, including (1) comprehensive assessment indicators system; (2) intelligent safety management; (3) cross-organization collaboration of safety management; (4) multilevel safety behavior perception and (5) comparative analysis of safety climate.
Originality/value
The findings can reveal the overall status of safety management research in the construction industry and represent a high-quality knowledge body of safety management research in the construction industry that accurately reflects the comprehensive knowledge map on the safety management research of construction industry. The findings also predict important highlights and future research directions of safety management research in the construction industry, which will help researchers in the safety management research of construction industry for future collaboration and work.

Abstract
Purpose
The purpose of this paper is to investigate the proper matches between institutional business ties (to state-owned enterprises (SOEs) and to banks) and firm capabilities (technological capability and marketing capability) in impacting the radical innovation of manufacturing firms in China.
Design/methodology/approach
Using the samples of 208 manufacturing firms in China, this study runs three regression models to test all hypotheses.
Findings
Ties to SOEs and ties to banks are positively related to radical innovation of manufacturing firms in China. Further, the technological capability and marketing capability have different functions on moderating the relationship between institutional business ties and radical innovation.
Practical implications
The results imply that managers of manufacturing firms should strive to establish close connections to those organizations that are set-up by government in China. In addition, managers should cautious about the synergies between different institutional business ties and different internal capabilities, and properly matching them to develop radical innovation.
Originality/value
This study enriches and extends the managerial ties literature by going beyond previous narrow focus on either business ties or political ties to address a particular type of organization that is set-up by the governments but operate in the business world. The findings of proper ties-capabilities matches provide nuanced understandings to dynamically manage external resources and internal capabilities for the synergetic benefits (e.g. radical innovation). This study also offer a theoretical paradigm (i.e. resource management model) for manufacturing firms to lessen the striking tension between the urgent needs for radical innovation and the hostile ground for conducting radical innovation.
