The triple helix (university-industry-government) is a dynamic cooperation model in the area of regional innovation. With the application of this model, the authors aim to address the mechanism of how multiple participants affect innovation efficiency against the research background of China Fuzzy-Set Qualitative Comparative Analysis (fs-QCA) is applied to conduct a multiple-case analysis. With the evaluation of 31 provinces in China, which have various innovation performances and degrees of regional cooperation, the authors find strong evidence to support the positive effects of multiple participants on regional radical innovation. Moreover, this article also finds two typical configurations of factors that contribute to high innovation efficiency. Based on the results, the authors propose policy implications to improve China’s regional innovation in different areas. Finally, this paper concludes with the discussion of future research orientations, which could focus on the differences in the triple helix among different industries in China.

The effects of natural resources on regional sustainable development is widely discussed by scholars and policymakers. However, most of the researchers concentrated on economic growth and technical development; evidence of how natural resources affect the soft environment is relatively lacking. Different from the neo-classical economics perspective of resource allocation, we used the evolutionary economics scope of factor creation and historical evolution to explore the effect on China’s regional entrepreneurship laid by the natural resource distribution on the early stage of China. The resource curse is explained from the aspect of regional entrepreneurship development in China. Based on the provincial panel data from China, in China’s industrial statistical yearbook and China’s statistical yearbook, we applied PLS-SEM (Partial Least Squares Structural Equation Model) to explore the path from natural resources to regional entrepreneurship. We also examined the mediating effect at the organizational scale, industry structure, the degree of regional openness, and the quality of human capital in the path between natural resource and entrepreneurship. The result shows that natural resources in the early-stage has negative effects on the growth of the entrepreneurship. Besides, industry structure and organizational scale are significant in terms of mediation effect in the path of the resource curse. An in-depth analysis is provided, and implications are discussed based on the results with the aim of revealing the mechanism and path-dependence of China’s regional development. The implications of this research include the suggestion of adapt the industry structure and motivate start-ups.

(1) Background: Public–private partnerships (PPPs) play an essential role in sustainable cities and are widely applied in the public environment, health, and transportation sectors. One of the main functions of PPP projects is to attract private capital to provide better public services and infrastructure. PPP projects require government investment, potentially threatening the debt of local governments. However, few scholars have shown attention to the relationship between PPP projects and local government debt. (2) Methods: Therefore, this study selects data from 36 cities in China from 2014 to 2018. Ordinary least squares (OLS), quantile regression, and placebo tests are used to investigate this claim. (3) Results: This study finds that PPP projects can affect local governments’ debt; based on this result, this study further proposes that the effect of PPP projects on local government debt has regional heterogeneity. Compared with eastern regions, PPPs in central and western areas of China have a noticeable impact on local government debt. This study also investigates the effect of different types of PPP projects on local government debt. In terms of the number of new additions, comprehensive urban development PPP projects have the largest effect on the exacerbation of government deb. In terms of the amount of new investment, environmental protection PPP projects have the greatest exacerbating effect on government debt. (4) Conclusion: These findings try to identify PPPs’ effect on local government debt. It is of potential reference for sustainable cities and helps to provide better transport, environmental, and health public services.
