海洋科技人才集聚对海洋经济绿色全要素生产率的影响研究

Study on the Impact of Marine Science and Technology Talent Agglomeration on Green Total Factor Productivity of Marine Economy

海洋科技人才是促进海洋经济高质量发展的重要资源和核心要素。文章构建了海洋科技人才集聚影响海洋经济绿色全要素生产率的理论机制,选取2006—2019年我国11个沿海省市的数据进行实证检验,并进一步分析海洋产业结构升级的中介作用和环境规制的调节作用。研究发现:海洋科技人才集聚与海洋经济绿色全要素生产率之间存在显著的“倒U”型关系;海洋科技人才集聚对海洋经济绿色全要素生产率的影响存在区域异质性,长江流域以南沿海地区表现出明显的“倒U”型关系,而长江流域以北沿海地区二者关系不显著;海洋产业结构升级在海洋科技人才集聚影响海洋经济绿色全要素生产率中发挥中介作用,且海洋产业结构升级能够显著促进海洋经济绿色全要素生产率提升;环境规制强化了海洋科技人才集聚对海洋经济绿色全要素生产率的“倒U”型影响。基于此,提出合理引导人才集聚、注重人才和产业适配、优化人才发展环境的政策建议。

Marine science and technology talents are important resources and core elements for promoting the high-quality development of marine economy.This paper constructs a theoretical mechanism of marine science and technology talent agglomeration affecting the green total factor productivity of the marine economy,selects the data of 11coastal provinces and cities in China from 2006to 2019for empirical testing,and further analyzes the mediating role of marine industrial structure upgrading and the moderating role of environmental regulation.The study finds that:there is a significant inverted U-shaped relationship between marine scientific and technological talent agglomeration and the green total factor productivity of the marine economy;there is regional heterogeneity in the impact of marine scientific and technological talent agglomeration on the green total factor productivity of the marine economy,with coastal areas south of the Yangtze River Basin showing a significant inverted U-shaped relationship,while the relationship is insignificant in coastal areas north of the Yangtze River Basin;the upgrading of marine industry structure plays a mediating role in the influence of marine scientific and technological talent agglomeration on the green total factor productivity of the marine economy,and the upgrading of marine industry structure can significantly promote the green total factor productivity of the marine economy;environmental regulation reinforces the inverted U-shaped impact of marine science and technology talent agglomeration on green total factor productivity in the marine economy.Based on this,policy recommendations are put forward to rationally guide the concentration of talents,focus on the matching of talents and industries,and optimize the environment for the development of talents.
