产业集聚对海洋绿色全要素生产率的影响研究

The Impact of Industrial Agglomeration on Marine Green Total Factor Productivity

文章基于2006—2019年我国沿海地区的面板数据,实证分析产业集聚对地区海洋绿色全要素生产率的影响。研究结果表明:产业集聚与地区海洋绿色全要素生产率的关系呈“倒U”形曲线,即产业集聚在初期有助于提升海洋绿色全要素生产率,当越过临界值之后,将对海洋绿色全要素生产率产生抑制作用;从区域异质性角度来看,北部、中部、南部地区的产业集聚对海洋绿色全要素生产率的影响不同,其中北部地区与整体情况相似,中部、南部地区存在地区差异。根据研究结论,各地应根据当地产业集聚情况,因地制宜保障海洋经济可持续发展。

Based on the panel data of coastal areas in China from 2006 to 2019,this paper empirically analyzed the impact of industrial agglomeration on regional marine green total factor productivity.The results showed that the relationship between industrial agglomeration and regional marine green total factor productivity showed an inverted“U”curve.Industrial agglomeration improved marine green total factor productivity in the early stage,and after crossing the critical value,it would have a suppressive effect on marine green total factor productivity.From the perspective of regional heterogeneity,the impact of industrial agglomeration on marine green total factor productivity was different in the northern,central and southern regions,among which the northern region was similar to the overall situation,while there were regional differences in the central and southern regions.According to the conclusion of the study,local governments should ensure the sustainable development of the marine economy according to the local industrial agglomeration and local conditions.
