摘要
建设统一大市场是构建新发展格局的基础支撑和内在要求。国家层面的城市群发展规划有利于提升区域市场一体化水平和资源配置能力,为企业合作创新奠定了良好的基础。文章以2015年以来国务院先后批复实施的十个国家级城市群发展规划为研究背景,利用双重机器学习方法和中国企业专利申请数据识别城市群发展带来的市场一体化效应对企业合作创新的影响。实证结果显示:城市群发展规划实施后,同一城市群内城市对的企业合作创新水平和创新质量得到了显著提高,市场一体化对企业合作创新具有明显的促进效应。异质性分析显示:由于产权性质和行业特征的不同,市场一体化对企业异地创新合作的影响在国内企业组别中更为明显,外资企业与国内企业的异地合作还有待提升。路径检验表明:国家级城市群规划实施能够通过协调城市间利益目标、减少产业同质化竞争等路径促进企业开展创新合作。机制分析显示:中心城市引导能够进一步强化国家级城市群建设对企业异地合作创新的促进效应。基于实证结果,文章提出了应充分利用城市群发展机遇、大力促进企业开展异地合作创新、加强市场整合、降低企业合作成本等政策建议。
Urban agglomeration is conducive to improving regional market integration and resource allocation capabilities,laying a solid platform for corporate collaborative innovation.Under the new development paradigm,the accelerated establishment of a unified market can lower transaction costs and improve cooperation efficiency,thereby making it a key approach to fostering high-quality collaborative innovation among enterprises.The research background of this paper is a series of urban agglomeration development plans approved by the State Council of the People’s Republic of China since 2015.Adopting statistics on the patent applications of Chinese enterprises,this paper employs the approach of double machine learning to examine how market integration brought about by urban agglomeration development affects corporate collaborative innovation.According to the empirical results,after the urban agglomeration development plans are put into practice,respective cities have experienced a significantly improved level and quality of collaborative innovation among enterprises.Heterogeneity analysis reveals that,due to differences in the nature of property rights and industry characteristics,the impact of market integration on inter-regional collaborative innovation is more pronounced in domestic enterprises,and market integration exerts a limited impact on the collaborative innovation between domestic and overseas enterprises.Path testing shows that nation-level urban agglomeration planning promotes corporate collaborative innovation by coordinating inter-city interest goals and reducing industrial homogeneous competition.Mechanism analysis shows that the introduction of central cities further strengthens the effective role that urban agglomerations play in boosting regional market integration.This paper has the following contributions:First,it analyzes the impact of market integration on corporate collaborative innovation from the perspective of the external shock brought by urban agglomeration development planning,providing a n
