摘要
以是否获批创新型城市建设试点单位为基本条件,采用多期双重差分法和三重差分法进行“准自然实验”,研究创新型城市建设对企业创新的促进作用及其作用机理。结果发现:创新型城市作为创新型国家建设的一个重要组成部分,能积极推动辖区内的企业创新活动;并且其主要通过增强企业集聚度、提高金融中介机构服务强度与扩大对外开放引进外商投资等途径对企业创新活动起到激励与保障作用。非试点城市应该借鉴这些先行经验,并结合自身的经济发展状况,推出系列政策以促进企业创新。
Based on the Quasi-Natural Experiment of whether assigned as innovative cities,the multi-period double difference method and the triple difference method are used to study the promotion effect of innovative cities on corporate innovation and its impact mechanism.The study finds that as an important part of the construction of an innovative country,innovative cities can actively promote corporate innovation by enhancing the concentration of enterprises,improving the service intensity of financial intermediaries,and expanding opening up.Non-pilot cities should learn from these pioneering experiences and combine their own economic development to introduce a series of policies to promote corporate innovation.
