摘要
基于2003—2019年108个样本城市的面板数据,借助普通面板数据模型和空间杜宾模型,实证检验了长江经济带生产性服务业与制造业协同集聚的技术创新效应及其异质性影响和空间溢出效应。研究表明:长江经济带产业协同集聚具有显著正向的技术创新效应,这在替换关键变量、剔除特殊样本、面板分位数估计和克服内生性问题等稳健性检验中始终成立;产业协同集聚的技术创新促进效应在2008年经济危机后变小,同时在东部和大型城市中最强,而西部和中小型城市则最弱且不显著;产业协同集聚和技术创新存在愈加明显的空间依赖性特征,协同集聚显著促进本地技术创新,但对邻近城市则产生显著的负向溢出效应,这在不同权重矩阵下仍成立。因此,应深入推进长江经济带产业协同集聚发展,塑造创新驱动发展新优势,积极发挥产业协同集聚的技术创新促进作用。
Based on the panel data of 108 sample cities from 2003 to 2019, using ordinary panel data model and spatial Durbin model, this paper empirically tested the technological innovation effect, heterogeneity influence and spatial spillover effects of industrial co-agglomeration of producer service and manufacturing industries in the Yangtze River Economic Belt. The results show that, the industrial co-agglomeration has a significant positive technological innovation effect, which was always valid in the robustness tests such as key substituting variables, eliminating special samples, estimating panel quantile and overcoming endogenous problems. The technological innovation promotion effect of co-agglomeration became smaller after the 2008 economic crisis, which was the biggest in eastern cities and large-scale cities, while it was the weakest and insignificant in western cities and small & medium-sized cities. The industrial co-agglomeration and technological innovation have increasingly obvious spatial dependence characteristics, and co-agglomeration significantly promotes local technological innovation, but it has a significant negative spillover effect on neighboring cities, which is still valid under different weight matrices. Therefore, it is necessary to further promote the industrial co-agglomeration and shape new advantages for innovation-driven development, and actively play the role of technological innovation promotion of co-agglomeration in the Yangtze River Economic Belt.
