产业协同集聚对绿色全要素生产率的空间效应

The Spatial Effect of Industrial Co-Agglomeration on Green Total Factor Productivity

文章根据影响机制理论提出假说,运用动态空间计量模型实证检验了产业协同集聚对GTFP(绿色全要素生产率)的影响以及空间溢出效应。研究表明,中国GTFP存在显著的“时间惯性”和空间相关性。无论是长期还是短期,产业协同集聚对本市GTFP的直接影响呈倒“U”型,并且对相邻城市GTFP产生显著的正向溢出效应。分行业回归结果表明,金融业与制造业协同集聚在长期和短期内均显著抑制本市GTFP的提升,交通运输、仓储和邮政业、计算机服务和软件业、科学研究和技术服务业与制造业分别协同集聚在长期和短期内均显著促进本市GTFP的提升,租赁和商务服务业与制造业协同集聚在长期和短期内对本市GTFP的影响均不显著,同时这些细分行业与制造业协同集聚对GTFP的空间溢出效应均存在明显差异。

According to the influencing mechanism,this paper proposes a hypothesis and uses dynamic spatial measurement model to empirically test the impact of industrial co-agglomeration on GTFP and its spatial spillover effect.The results show China's GTFP has significant time inertia and spatial correlation.Whether in the long-term or short-term,the direct impact of industrial co-concentration on the city's GTFP is inverted U-shaped,and it has a significant positive spatial spillover effect on GTFP of neighboring cities.The regr-ession results of different industries show the co-agglomeration of financial industry and manufacturing industry has significantly inhibited the city's GTFP in the long and short term.The co-agglomeration of transportation,warehousing and postal industry,computer services and software industry and manufacturing industry and scientific research and technical services have respectively promoted the city's GTFP significantly.The co-agglomeration of leasing and business services and manufacturing has not a significant effect on GTFP.At the same time,there are obvious differences in the spatial spillover effects of the co-agglomeration of these sub-sectors and manufacturing industries on GTFP.
