The purpose of this paper is to investigate the relationship between the chief data officer’s (CDO) presence and firm performance, and the moderating effect of firm size.

The performance data for 64 treatment firms with CDOs and 64 control firms without CDOs is collected from Compustat database. The Wilcoxon signed-rank test is used to analyze the performance differences between treatment firms and control firms. Hierarchical regression method is used to test the moderating effect of firm size.

The results indicate that the profit ratios of treatment firms are significantly improved after the appointment of CDOs, and the profit ratios of treatment firms are significantly higher than that of the control firms. For the cost ratios, the findings provide some empirical evidence revealing two of the cost ratios are lower and only one ratio is higher for the treatment firms after CDOs’ appointment. Firm size moderates the relationship between the CDO’s presence and firm performance indicator, ROS, in the same direction. Firm size has no moderating effect on relationships between CDO’s presence and other performance indicators.

The findings provide practical insights that will help managers to realize the importance of CDOs and their work. CDOs would bring some cost to the firms, but they would bring more profit to firms. In addition, if for large firms, the CDO’s presence would bring more ROS.

The study explores the relationship between the CDO’s presence and firm performance. It is the first attempt to explore the CDO’s presence and the cost performance in the specific time period, and the study is also the first attempt to analyze the moderating effect of the firm size on the relationship between the CDO’s presence and firm performance.

This paper seeks to examine how leaders shape employee creativity by using interpersonal emotion management (IEM) strategies. Drawing on the social information processing (SIP) theory, the authors argue that psychological safety translates leader problem-focused IEM into employee creativity, an impact which is moderated by organizational justice.

Data were collected in two waves from 201 employees and their leaders in China. Regression analysis was used to test the hypotheses.

Leader problem-focused IEM is positively related to employee creativity, and this relationship is mediated by psychological safety. Organizational justice positively moderates the relationship between leader problem-focused IEM and psychological safety as well as the indirect relationship between leader problem-focused IEM and employee creativity via psychological safety.

This paper identifies a novel and useful predictor of employee creativity from the perspective of leader problem-focused IEM and provides practical insights for organizations regarding ways of improving employee creativity.

This paper attempts to develop a model of the “entrepreneurial state” based on Schutz’s theory of human action. It aims to improve the understanding of the nature of state action and of entrepreneurial processes in the public sector. From the subjectivist paradigm, this paper argues that the state, like private enterprises, has purposes and public sector agents engage in conscious actions toward chosen goals which can be attended only in the future. In terms of mental constructs, the public entrepreneur’s opportunity identification activities involve four major stages. Using their imagination, they project, select, elaborate on and eventually implement the opportunity ideas. Given structural uncertainty, public sector agents will unavoidably make errors in trying to plan and implement a new project. Over time, with learning and the growth of knowledge, errors are then eliminated. The revision of plans by state agents – the source of policy change – is thus portrayed as a continuous process of learning and experimentation oriented towards the future. Since entrepreneurship implies strategic planning, and the nation needs to formulate development strategies with the aim of building competitive advantage, the last part of the paper discusses entrepreneurial intervention in association with the state’s resource base and capabilities. By referring to the Asian newly industrialised economies, this paper suggests a new approach to understanding state action and government intervention.

This paper aims to develop an efficient numerical method for nonlinear transient heat conduction problems with local radiation boundary conditions and nonlinear heat sources.

Based on the physical characteristic of the transient heat conduction and the distribution characteristic of the Green’s function, a quasi-superposition principle is presented for the transient heat conduction problems with local nonlinearities. Then, an efficient method is developed, which indicates that the solution of the original nonlinear problem can be derived by solving some nonlinear problems with small structures and a linear problem with the original structure. These problems are independent of each other and can be solved simultaneously by the parallel computing technique.

Within a small time step, the nonlinear thermal loads can only induce significant temperature responses of the regions near the positions of the nonlinear thermal loads, whereas the temperature responses of the remaining regions are very close to zero. According to the above physical characteristic, the original nonlinear problem can be transformed into some nonlinear problems with small structures and a linear problem with the original structure.

An efficient and accurate numerical method is presented for transient heat conduction problems with local nonlinearities, and some numerical examples demonstrate the high efficiency and accuracy of the proposed method.

Recent studies have advocated the impact of technological innovation capabilities (TIC) on firms' competitive performances. This paper adopts a study framework of innovation audit to examine the relevance of TIC on the innovation performance of the electronics industry in Hong Kong (HK)/Pearl River Delta region.

Empirical data were acquired through a recent survey of electronics firms in the region. Pearson correlation and regression analysis were employed to examine the relationship between TIC and innovation performance.

The results verify that R&D, resource allocation, learning, and strategy planning capabilities can significantly improve the innovation sales. R&D and resource allocation capabilities can also significantly improve new product introduction.

The paper contributes to existing literature by studying the impact of TIC on innovation performance in HK. It also explores two out of seven TIC – R&D and resource allocation capabilities – to improve firms' innovation performance in the region.

This paper is one of very few that provide empirical evidence of the TIC and innovation performance in HK. It also revisits the audit framework proposed by recent innovation studies, which helps theoretical development.

This study aims to research the development trend, research status, research results and existing problems of the steel–concrete composite joint of railway long-span hybrid girder cable-stayed bridge.

Based on the investigation and analysis of the development history, structure form, structural parameters, stress characteristics, shear connector stress state, force transmission mechanism, and fatigue performance, aiming at the steel–concrete composite joint of railway long-span hybrid girder cable-stayed bridge, the development trend, research status, research results and existing problems are expounded.

The shear-compression composite joint has become the main form in practice, featuring shortened length and simplified structure. The length of composite joints between 1.5 and 3.0 m has no significant effect on the stress and force transmission laws of the main girder. The reasonable thickness of the bearing plate is 40–70 mm. The calculation theory and simplified calculation formula of the overall bearing capacity, the nonuniformity and distribution laws of the shear connector, the force transferring ratio of steel and concrete components, the fatigue failure mechanism and structural parameters effects are the focus of the research study.

This study puts forward some suggestions and prospects for the structural design and theoretical research of the steel–concrete composite joint of railway long-span hybrid girder cable-stayed bridge.

This study aims to examine the influence of regulatory framework (RF), market dynamism (MDY), competitive intensity (CIN) and environmental public concern (EPC) on responsible innovation (RI) in the manufacturing SMEs of a developing country. Furthermore, the study examines the influence of RI on sustainable competitive advantage (SCA). Moreover, big data adoption (BDA) is used as a moderator between RI and SCA.

The study’s hypotheses are evaluated using the structural equation modeling methodology. The study collected data from a sample of 487 owners/managers of manufacturing SMEs using simple random sampling technique.

The results explain that RF, MDY, CIN and EPC significantly determine RI. Moreover, RI significantly determines SCA. Besides, BDA significantly moderates between RI and SCA.

For manufacturing SMEs to obtain SCA, RI is essential, and BDA is crucial to meet changing consumer demands for environmentally friendly products. With more environment-friendly initiatives, the natural environment will become more sustainable. Moreover, this research offers a comprehensive perspective to the public regarding the extent to which manufacturing enterprises are adopting RI and BDA.

The majority of earlier research on RI and BDA has been carried out in the context of large businesses. Institutional theory was used to look into the drivers of RI. Furthermore, BDA is used as moderating variable between RI and SCA.

This study estimates the income elasticities of calorie, macronutrients (carbohydrate, protein and fat) and key micronutrients including cholesterol, vitamin A, vitamin C, sodium, potassium, calcium, iron, zinc and insoluble fiber separately for urban and rural adults aged 18–60, using China Health and Nutrition Survey data set from 2004 to 2011.

A semiparametric model, a two-way fixed-effects model and a quantile regression approach are employed to estimate nutrient–income elasticities.

The income elasticities of calorie, protein, fat, cholesterol and calcium are in the range of 0.059–0.076, 0.059–0.076, 0.090–0.112, 0.134–0.230, 0.183–0.344 and 0.058–0.105, respectively. The income elasticity of each of the other nutrients is less than 0.1. The income elasticities of calorie and the majority of nutrients included are larger for rural residents than for urban residents and for low-income groups than for medium- and high-income groups. Overall, in spite of having a relatively small impact, income growth is shown to still have an impact on improving the nutritional status of Chinese adults.

This study estimates nutrient–income elasticities separately for urban and rural adults, expanding the scope of the study regarding the impact of income on the nutritional status in China. Moreover, this study uses a pooled sample generated from the personal food consumption records covering foods consumed at home and away from home during 2004–2011, which is thus likely to more comprehensively reveal the causal relationship between income growth and changes in the nutritional status in China.

This study empirically investigates how ambidextrous innovations and their balancing affect the supply chain financing performance (SCFP) of small and medium-sized enterprises (SMEs), based on signaling theory. Moreover, this study explores the moderating effect of the breadth and depth of digital technology deployment on the relationship between ambidextrous innovations and the SCFP of SMEs.

A mixed-methods design is used, including a qualitative study and a quantitative study. Qualitative data have been collected from six multi-cases in different industries. Questionnaire data have been collected from 259 SMEs in China, and a multiple regression model is used to verify the research hypotheses.

The findings indicate that, in supply chain financing, both exploitative innovation and exploratory innovation are helpful in improving the SCFP of SMEs. For resource-constrained SMEs, a relative balance between exploitative innovation and exploratory innovation can help improve SCFP. The breadth of digital technology deployment can strengthen the relationship between exploitative innovation and SCFP, while the depth of digital technology deployment can weaken the relationship between exploratory innovation and SCFP. In addition, increasing the depth of digital technology deployment strengthens the positive correlation between the relative balance of ambidextrous innovations and SCFP.

To effectively obtain supply chain financing, SMEs can either concentrate their limited resources on a single type of innovation or use relative balance strategies to simultaneously pursue two innovations. In addition, in the process of obtaining supply chain financing by ambidextrous innovations, SMEs should appropriately deploy digital technologies.

This study first deconstructs the impact mechanism of ambidextrous innovation capabilities on SCFP based on signaling theory, and then discusses the balancing effect of ambidextrous innovations on SCFP in the cases of resource-constrained SMEs. This study also goes further and finds the negative moderating effect of digital technology deployment in the process of supply chain financing.
