国家中心城市肩负着引领区域经济发展,促进地区对外开放的重要使命,其创新引领作用将为企业合作创新搭建良好平台.以实施国家中心城市建设事件为准自然实验,利用交错双重差分模型识别国家中心城市建设对企业异地合作创新的影响.研究发现:国家中心城市建设能显著提高中心城市与其他城市企业联合申请专利的数量,国家中心城市的创新带动作用明显;异质性分析显示,国家中心城市建设对东部地区、民营企业、同一学科内的企业异地合作创新影响效应更强;机制检验表明,国家中心城市通过提升市场一体化水平、推进区域产业分工、增强经济关联等渠道影响企业异地合作创新;进一步研究发现,国家中心城市的创新引领效应影响范围有限,但企业合作创新的质量较高,创新的持续性和稳定性较好.因此,地方政府应有效利用国家中心城市建设机遇,促进城市间企业合作创新,推动企业高质量发展.
The national central city shoulders the important mission of leading regional economic develop-ment and promoting regional opening up.Their leading roles in innovation will provide a good platform for enterprise cooperation and innovation.Taking national central cities as the research object,central city con-struction is regarded as a quasi-natural experiment by using a difference-in-differences model to identify the impact of national central city construction on off-site collaborative innovation among enterprises.The results indicate that the construction of national central cities can significantly increase the number of joint patent applications between central cities and enterprises in other cities.The innovation-driven effect of national central cities is obvious.The heterogeneity analysis shows that the construction of national central cities had a stronger impact on the eastern region,private enterprises,and long-distance cooperative innovation within the same discipline.The mechanism test suggests that the national central cities influence the remote collab-orative innovation among enterprises by improving market integration,promoting regional industrial divi-sions,and enhancing economic ties.Further research demonstrates that the innovation-leading effect of na-tional central cities is of limited scope,but the quality of long-distance cooperative innovation among enter-prises is higher,and the sustainability and stability of innovation are better.Therefore,local governments should effectively utilize the opportunities of national central city construction to promote inter-city enterprise collaborative innovation,and promote the high-quality development of enterprises.
