| In the process of economic development,cities are prone to the impact of external risks such as trade friction and COVID-19.However,the difference in economic resilience makes cities show different economic development trends after experiencing risks.Cities with stronger economic resilience can recover economic growth as soon as possible,while cities with weaker economic resilience are prone to economic stagnation or even recession.As a key factor to enhance the resilience of urban economy,innovation and entrepreneurship can give birth to new industries by reintegrating idle resources,replace high energy consumption and high pollution enterprises with high-tech enterprises,gradually form new productivity,promote the transformation and upgrading of industrial structure,enhance the ability of urban economy to resist the impact of external risks,and form strong economic resilience.Therefore,China should effectively enhance the level of innovation and entrepreneurship and leverage its role in enhancing the resilience of urban economy.In this context,it is of great theoretical value and practical significance to explore the influence of innovation and entrepreneurship level on urban economy.In this thesis,innovation entrepreneurship and urban economic resilience are included in the research system.According to the theory of regional innovation system,entrepreneurship theory,path dependence theory and the theory of complex adaptive system,combing the literature,further explore creative level of urban economic resilience mechanism.At the same time,combing with the availability of data,this paper uses the data of 265 cities from 2011 to 2020 as research samples,uses the entropy method to measure the index system of urban economic resilience,and empirically tests the enhancement effect of innovation and entrepreneurship level on urban economic resilience and the spatial spillover effect through the fixed effect model,the intermediary effect model and the spatial econometric model.The results showed that:(1)The level of innovation and entrepreneurship can significantly 1enhance the city economic resilience,but exists geographical location,resources endowment and heterogeneity of urban scale.In terms of geographical location,innovation and entrepreneurship can significantly promote urban economic resilience in both eastern and central regions,but not in western regions.In terms of resource endowment and city size,the level of innovation and entrepreneurship has a stronger effect on the economic resilience of non-resource-based and large-scale cities.(2)The influence of innovation and entrepreneurship on urban economic resilience is mediated by talent reserve and industrial structure,innovation and entrepreneurship can improve urban economic resilience by improving human resources and optimizing industrial structure.(3)There is a positive spatial correlation between the level of innovation entrepreneurship and the resilience of urban economy.The level of innovation and entrepreneurship in a region can not only enhance the economic resilience of the region,but also enhance the economic resilience of neighboring regions.Finally,based on the above theoretical analysis and the results of the study,put forward some policy suggestions: the value innovation entrepreneurship development,improve innovation entrepreneurship related the difficulty of innovative undertaking financing,solve the problem of initial capital shortage;Strengthen cooperation between schools and enterprises,effectively improve the level of innovation and entrepreneurship,accelerate the training of compound innovation and entrepreneurship talents,and give play to the effect of talent reserve;According to the actual situation of each city,formulate differentiated development goals,focus on the development of competitive industries,enhance the ability to resist external risks;Promote the sharing of information resources among regions,help the development of inferior industries through mutual assistance of regional advantageous industries,so as to realize the complementary advantage of resources. |
