摘要
基于2003-2019年我国284个地级及以上城市的面板数据,采用加入双向固定效应的空间杜宾模型,实证检验了专业化集聚和多样化集聚对城市科技创新绩效的影响。结果表明,这两种产业集聚与城市科技创新绩效之间均存在倒“U”型曲线关系;样本时期内,我国城市两种产业集聚的平均水平均位于倒“U”型曲线左侧,其中多样化集聚程度已接近总体最优水平,而专业化集聚程度仍有较大提升空间;此外,对城市自身最优的集聚程度高于对其他城市最优的集聚程度。未来,应推动创新合作基础上的城市创新职能重构,重点提升专业化集聚水平,优化多样化集聚质量,构建支撑高质量发展的城市创新格局。
This study analyses empirically the impacts of specialized agglomeration and diversified agglomeration on urban innovation performances based on the panel data of 284 cities in China from 2003 to 2019,using the spatial Durbin model with two-way fixed effects.It is shown that relationships between urban innovation performances and the two kinds of industrial agglomeration are characterized by the inverted“U”curves.It is also shown that during the sample period,the average degrees of the two kinds of industrial agglomeration are both on the left side of the inverted“U”curves,where the average degree of diversified agglomeration has been closed to the overall optimal degree,while the average degree of specialized agglomeration has still much space for improvement.Additionally,the optimal degree of agglomeration for the cities themselves is higher than that for other cities.This study suggests promoting the reconstruction of urban innovation functions based on urban innovation cooperation,upgrading levels of specialized agglomeration,and improving qualities of diversified agglomeration,so as to build patterns of urban innovation that supports high-quality development.
