高等教育集聚促进长江中游城市群创新创业的空间杜宾模型*

Spatial Durbin model of advanced education agglomeration promoting the innovation and entrepreneurship of urban agglomeration in the middle reaches of the Yangtze river

摘要:

基于长江中游城市群2003-2016年面板数据的高等教育集聚、创新和创业指标体系,利用测算的综合指数进行全局空间自相关检验和模型选择检验；构建空间经济地理权重矩阵,建立空间面板杜宾模型,实证研究高等教育集聚对创新和创业的影响。研究表明：创新和创业存在不同程度的空间溢出效应,财政支出影响创新能力却不影响创业水平,高等院校教师数对创新创业的影响并不显著；高等院校数在抑制本市创新和创业能力的同时却促进了邻近城市的创新能力,而高等院校在校学生数在促进本市创新和创业能力的同时会抑制邻近城市的创新能力；最后,从财政支出和高校发展的角度,提出了促进城市群创新创业的政策建议。

Abstract:

Based on the panel data of urban agglomeration in the middle reaches of Yangtze River from2003 to2016,the index system of higher education agglomeration,innovation and entrepreneurship is constructed and the test of spatial autocorrelation and model selection are carried out by using the calculated composite index,then the spatial economic geographical weight matrix is being introduced. To study empirically the effect of higher education agglomeration on innovation and entrepreneurship it establishes the spatial panel Durbin model. The results show that there are different degrees of spatial spillover effect between innovation and entrepreneurship,but fiscal expenditure does affect the ability of innovation but not the level of entrepreneurship in the mean time,the influence of the number of College Teachers on Innovation and Entrepreneurship is not significant. The number of universities not only inhibits the ability of innovation and entrepreneurship itself,but also promotes the innovation ability of neighboring cities. At the same time,the number of college or university students will restrain the innovation ability of the neighboring cities while promoting the innovation and entrepreneurial ability of itself; Finally from the perspective of financial expenditure and the development of colleges and universities,the paper puts forward some policy suggestions to promote innovation and entrepreneurship of urban agglomeration in the middle reaches of Yangtze River.
