创业活力、创新能力与城市经济发展效率——基于283个地级市数据的实证检验

Entrepreneurial Vitality, Innovation Ability and Urban Economic Development Efficiency——Empirical Study Based on the Data of 283 Prefecture Level Cities

基于双创的视角,使用283个地级市的数据检验了创业活力和创新能力对城市经济发展效率的影响。研究发现:创业活力和创新能力对经济发展效率均具有促进作用,但二者的交互项会对经济发展效率产生逆向冲击;东部和中部地区的创业活力显著促进了经济发展效率的提升,而西部地区的创业活力对经济发展效率的作用不显著;东、中、西部地区的创新能力均显著促进了地区经济发展效率的提升,而东部地区创业活力与创新能力的交互项则对经济发展效率产生了抑制作用。分组检验表明,高水平创业活力和创新能力的组合更能促进经济发展效率的提升。面板门槛回归表明,当创业活力小于0.704时,创新能力抑制了经济发展效率,而当创业活力大于1.372时,创新能力提升了经济发展效率。

Based on the perspective of mass entrepreneurship and innovation,this paper used the data of 283 prefecture-level cities to test the impact of entrepreneurial vitality and innovation ability on urban economic development efficiency.The study found that,entrepreneurial vitality and innovation ability both had a promoting effect on economic development efficiency,but the interaction of the two had a reverse shock.The promoting effect of entrepreneurial vitality was more obvious in eastern and central regions than that in western regions.Innovation ability had an evident promoting effect in all regions,but the interaction of entrepreneurial vitality and innovation ability in eastern regions had inhibited economic development efficiency.Group inspection showed that,the combination of higher-level entrepreneurial vitality and innovation ability could better promote the improvement of economic development efficiency.And panel threshold regression revealed that,when entrepreneurial vitality index was smaller than 0.704,innovation ability would inhibit economic development efficiency,and when entrepreneurial vitality index was bigger than 1.372,innovation ability would promote economic development efficiency.
