摘　　要：通过匹配2011-2020年城市层面产业协同集聚指数与深交所中小板、创业板企业数据,采用双固定效应模型,实证检验产业协同集聚对中小企业专精特新发展的影响及作用机制。结果显示,产业协同集聚可以显著推动中小企业专精特新发展,且这种影响在低供应商集中度企业、高数字化水平城市和高端生产性服务行业表现更显著。机制检验结果表明,产业协同集聚可以通过促进企业技术创新、降低企业交易成本和减小企业经营风险,推动中小企业专精特新发展。The"specialized,refined,differential and innovative"(SRDI)enterprises have been focusing on segmented markets for a long time by integrating innovative elements with key links,and mastering the"unique skills".SRDI enterprises are important support for the future industrial chain and the main force to break through the"bottleneck"of key technologies.Industrial collaborative agglomeration is a new trend in the development of modern industries,manifested as the process of vertically related and horizontally complementary industries achieving industrial integration through value chain reconstruction and supply chain integration.It has the characteristics of economies of scale,economies of scope,and external economies,and can provide more cooperation opportunities and development space for small and medium-sized enterprises.The industry generally believes that the industrial ecosystem of agglomeration and symbiosis is the matrix for cultivating SRDI enterprises.Therefore,does industrial collaborative agglomeration have a significant promoting effect on SRDI development in small and medium-sized enterprises?This article takes small and medium-sized board and ChiNext board enterprises on the Shenzhen Stock Exchange as research samples,matches the urban-level industrial collaborative agglomeration index according to the cities where the enterprises are located,and uses various econometric techniques such as the double fixed effect model,intermediary effect model,instrumental variable method,and propensity score matching method to empirically test the impact of industrial collaborative agglomeration on the SRDI development of small and medium-sized enterprises.It is found that,firstly,multiple robustness tests,including endogeneity tests,show that industrial collaborative agglomeration can significantly promote the SRDI development of small and medium-sized enterprises.Second,there is significant enterprise heterogeneity,city heterogeneity,and industry heterogeneity in the promotion effect of industrial collaborative aggl
