摘　　要：作为一种具有明显正外部性的非正式制度,信用文化对城市创新发展的影响正成为重要的研究课题。本文基于中国各地级市的专利被引用数据,从社会信用文化“软”约束的独特视角出发,重点检验了社会信用文化对创新知识溢出的影响机制。实证发现:社会失信环境阻碍了城市创新知识溢出,不论是个人失信指标还是企业失信指标都验证了这一结论,尤其是在发达的大型城市更为明显;进一步分析表明,社会失信环境下企业融资约束程度的提高显著抑制了城市创新知识溢出的水平,而把人力资本管理与人才信用建设纳入国家发展战略中,进一步缓解创新知识的外溢“壁垒”;与此同时,考察失信名单公开的“冲击”效应和信用城市试点的“示范”效应,应用DID和DDD的检验方法,证实了信用政策能有效缓解失信对城市创新知识外溢产生的阻碍作用。研究结论对于建立健全事前甄别和失信惩戒制度,完善社会信用基础性法律法规,发挥政府诚信示范作用,从而营造优良的创新知识溢出环境具有启示意义。Economic growth has long been a closely watched issue for economists and policymakers.In the study of neoclassical economic theory,it is never the product of exogenous factors,but is triggered by a new combination of endogenous conditions and production factors,which is often called the process of“creative destruction”.As Solow points out,technological innovation is not only an important factor in promoting economic growth,but also a source of power for building an innovative nation.How to promote innovative development,solve the“stuck neck”technical problems in production applications,and achieve high-quality economic development is the key focus of building a new development pattern.Technological innovation is the driving force and source of a country’s sustained economic growth,and for technological progress,what is more important is the“secondary creation”of innovation results and the spatial dissemination of knowledge.Under the background of the“new normal”,a good contract environment and credit culture are the premise and foundation for the operation of the market economy,as well as a favorable guarantee for promoting socio-economic development and technological innovation,and an important tool to promote the spillover of urban innovation knowledge.As an informal system with obvious positive externalities,the impact of credit culture on urban innovation and development is becoming a research topic that economists are keen on.Based on the patent citation data of various cities in China,this paper focuses on examining the influence mechanism of social credit culture on the spillover of innovative knowledge from the unique perspective of the“soft”constraint of social credit culture.Empirical results show that the social untrustworthy environment seriously hinders the level of urban innovation knowledge spillover,and both the indicators of personal untrustworthiness and the indicators of corporate untrustworthiness perfectly verify this conclusion,especially in developed large cities.The r
