基于我国内地30个省（自治区、市）面板数据，利用多层线性回归模型，探究国家创新政策、合作强度、技术多元化对区域创新绩效的跨层次影响机制。结果表明：国家创新政策有利于提升区域创新绩效，创新主体合作强度在其中发挥中介作用，技术多元化则发挥调节作用。具体而言，技术多元化对区域内创新绩效发挥正向调节作用，对区域间创新绩效发挥负向调节作用，进而负向调节合作强度的中介作用。最后，从创新政策针对性、主体合作、技术多元化方面提出促进区域创新绩效提升的对策建议。

Innovation is the first driving force for development. China's continuous improvement of its scientific and technological innovation system has led to the continuous improvement of its innovation-driven development capabilities, with innovative achievements in cutting-edge fields such as artificial intelligence and quantum technology emerging, and the turnover of technology contracts increasing by nearly 30%. While previous research has thoroughly examined the varied effects of innovation policies on fostering innovation, it has predominantly concentrated on the mechanisms through which individual policies influence innovation performance, particularly within the realm of enterprise innovation. There is a noticeable gap in understanding how comprehensive national innovation policies can bolster regional innovation performance, and a scarcity of studies that delve into the mechanisms linking these policies to regional innovation outcomes. Furthermore, as a form of macroeconomic policy, the influence of national innovation policies on regional innovation systems is multifaceted and intricate. Variations in implementation across different regions, sectors, and stages may lead to divergent impacts on regional innovation systems. However, research on innovation policies and regional innovation that accounts for regional disparities and investigates cross-level impact mechanisms using panel data is sparse. As an important part of the national innovation system, regional innovation plays an important role in promoting economic and social development, enhancing regional competitiveness, and implementing new development concepts. Regional innovation capacity is not only affected by innovation resources within the region, but also regulated by national innovation policies. Therefore, it is of great theoretical and practical significance to explore the impact of national innovation policy on regional innovation performance and its internal mechanism.
This paper focuses on the diversity and complexity of the impact of national innovation policy on regional innovation systems.As a macro-control policy, these policies may yield varying outcomes across different regions, fields, and stages of implementation. Therefore, in order to investigate the impact of innovation policies at the national level on innovation performance at the regional level, the mediating role of innovation subject cooperation intensity in this process, and the moderating role of regional technology diversification in this process, this paper constructs a cross-level model without confusion based on the panel data of 30 provinces in China. The study adopts regional innovation performance as the dependent variable, with the number of invention patent applications serving as the metric for assessing this performance. It approaches the quantification of innovation policies from the perspective of policy intensity, utilizing national innovation policies as the explanatory variables. The study identifies cooperation intensity as a mediating variable and technological diversification as a moderating variable. Control variables encompass factors such as education level, industrial structure, the scale of high-tech enterprises, road density, and the density of mobile phone switches.The study focuses on the intra-group effect and inter-group effect to empirically test the cross-level impact mechanism of national innovation policy on regional innovation performance.
It is found that (1) national innovation policy has a significant impact on regional innovation performance; (2) cooperation intensity plays a mediating role between national innovation policies and regional innovation performance; (3) cooperation intensity contributes to the improvement of regional innovation performance, and technological diversification plays a moderating role in it.
In order to further improve regional innovation performance and strengthen the impact of innovation policies on regional innovation performance, this paper puts forward corresponding countermeasures and suggestions from the aspects of improving the pertinence of innovation policies, strengthening cooperation intensity among innovation entities, and promoting the diversified development of regional technologies.
This paper clarifies the influencing mechanisms of national innovation policies, regional innovation performance, cooperation intensity of innovation subjects, and technology diversification, expands the previous research on the impact of innovation policies on regional innovation, and enriches the impact model of regional innovation performance. Furthermore, it provides recommendations for optimizing innovation policies and enhancing regional innovation performance in light of empirical analysis results. These contributions provide beneficial supplements to existing research and contribute to the realization of high-quality economic development in China.
