Based on the data of 278 prefecture-level city panels in China from 2008 to 2020, this paper presents the policy of innovative pilot city as a quasi-natural experiment. It is found that (1) the implementation of innovative urban policy can significantly improve the level of science and technology entrepreneurship, but the pilot policy has a time lag effect and has a continuous promoting effect since the third year. (2) For large cities, areas with high levels of economic development, central and eastern regions and cities with high new infrastructure, innovative cities can improve the level of technological entrepreneurship; (3) Innovative cities improve the level of technological entrepreneurship by improving the incubator of technological enterprises and strengthening the flow of human capital; (4) The effect of the establishment of innovative cities on the level of technological entrepreneurship mainly shows that the siphon effect does not show radiation effect, and this siphon effect mainly improves the level of technological entrepreneurship by increasing the number of incubators of technological enterprises.
基于 2008 年至 2020 年中国 278 个地级城市面板数据,本文以创新型试点城市政策为准自然实验,发现:(1)创新城市政策的实施能够显著提升科技创业水平,但试点政策存在时滞效应,且自第三年起具有持续推动作用。(2)对大城市、经济发展水平较高、中东部地区和新基建水平较高的城市而言,创新城市能够提升科技创业水平。(3)创新城市通过提升科技企业孵化器和加强人力资本流动来提升科技创业水平。(4)创新城市建设对科技创业水平的影响主要表现为虹吸效应,不具有辐射效应,且这种虹吸效应主要通过增加科技企业孵化器数量来提升科技创业水平。
