科技创新效率与区域经济韧性交互分析——基于珠三角地区的实证

Interactive Analysis of the Efficiency of Technological Innovation and Reginal Economic Resilience:the Empirical Evidence of the Pearl River Delta

测算珠三角地区科技创新活动研发和经济产出两阶段效率,探讨两阶段效率在时空上的异质性。构建包含科技创新效率、经济韧性和产业多样化的联立方程组,对三者关系进行分析。结果发现,珠三角地区科技创新研发与经济产出效率在空间上存在显著异质性;科技创新效率有助于增强经济韧性,经济韧性也可以提高科技创新效率;现阶段珠三角地区产业相关多样性通过降低研发阶段效率间接削弱经济韧性,无关多样性则与之相反。研究结论对于珠三角地区乃至全国各地提高科技创新活动效率、推动创新驱动发展战略实施、构建区域经济韧性具有重要意义。

China's economic development is in a critical period of transformation,and the previous development power is not enough to continue high-speed economic growth.We should emphasize the transformation of the economy to high-quality development.As one of the important strategies for high-quality economic development,can innovation-driven strategy effectively have a positive effect on economic development?It is also worthy of further discussion of how to reasonably measure the efficiency of scientific and technological innovation activities.While the foundation of China's internal economic development is constantly changing,COVID-19',anti globalization trend and a series of foreign negative factors are also constantly challenging China's economic resilience.As one of the regions with the most developed level of scientific and technological innovation and economic development in China,the Pearl River Delta is a representative region to study the relationship between scientific and technological innovation efficiency and economic resilience.This paper puts forward two research questions.The first is whether the current efficiency of scientific and technological R&D activities in the Pearl River Delta is efficient,and What the characteristics of temporal and spatial distribution are;the second is whether there is an interaction between scientific and technological innovation efficiency and economic resilience,and whether there will be phased differences in the direction and mechanism of influence between the two.Nine cities in the Pearl River Delta are taken as the research object,their economic resilience and the two-stage efficiency of scientific and technological innovation activities are calculated and analyzed to obtain the relevant data sets of 9 cities in 13 years.The correlation between them is constructed by Tobit model and simultaneous equation model.In order to further broaden the connection ways between them,the study takes the perspective of industrial diversity to analyze the transmission role of industrial structure between economic resilience and the efficiency of scientific and technological innovation activities.The results show that there are obvious differences in the efficiency of scientific and technological R&D stage and economic output stage in the Pearl River Delta,and there are also significant spatial heterogeneity in each stage.In the empirical process,there is a two-way causal relationship between the efficiency of the two stages of scientific and technological innovation and economic resilience in Tobit model,which will produce endogenous problems.The empirical results of simultaneous equations model prove that if considering the heterogeneity of region and time,the two-stage efficiency of scientific and technological innovation has a significant positive effect on economic resilience.Economic resilience can also support the two-stage efficiency,and the two-stage efficiency of scientific and technological innovation in areas with high economic resilience will be higher.When scientific and technological innovation activities are at different R&D levels,their innovation path and innovation content will not remain unchanged.Scientific and technological innovation activity is an uninterrupted activity.The development of R&D stage needs technical foreshadowing and support.Industrial diversification does not have a direct and significant impact on economic resilience,but it can indirectly affect economic resilience through the R&D stage of scientific and technological innovation.This paper combines the research results of economic resilience theory,system efficiency theory and industrial diversification theory,takes the regional economic resilience and the efficiency of scientific and technological innovation activities as the research object.Different from the previous research,this paper creatively connects the economic resilience and the efficiency of scientific and technological innovation activities with simultaneous equations,Theoretical analysis and empirical research are carried out from an interactive research perspective,which expands the research ideas of the relationship between the two.The empirical results also support this theoretical hypothesis,and have guiding significance for building regional economic resilience and improving the efficiency of scientific and technological innovation activities.First,compared with the economic output stage,the scientific and technological innovation stage should become the focus of government departments and enterprises;moreover,the differences in the efficiency of regional scientific and technological innovation are mainly concentrated in the stage of scientific and technological innovation,which urgently needs the government's macro-control to adapt the elements of scientific and technological innovation.Second,in areas with a higher level of high-tech innovation,relevant departments should pay attention to the non relevant diversification of structure and guide the integrated innovation across departments and fields when guiding the transformation and upgrading of industrial structure.Third,the diversification of regional industrial layout and the development of non related industries should be considered in policy formulation.
