制造业集聚、异质性投资与黄河流域能源环境效率

Manufacturing Agglomeration,Heterogeneous Investment and Energy and Environmental Efficiency in the Yellow River Basi

积极推进多元投融资机制,合理布局制造业集聚区对建设黄河流域生态保护和高质量发展先行区尤为重要。在考虑生态环境承载力的前提下,运用非径向方向距离函数测度2006~2021年黄河流域能源环境效率,通过空间Tobit杜宾模型研究制造业本文集聚对能源环境效率的非线性影响,并探讨异质性投资的作用。结果表明制造业集聚对能源环境效率存在倒U型影响,邻地的制造业集聚对本地的能源环境效率具有正U型溢出效应;机制分析表明在制造业集聚与能源环境效率的关系中,内资存在倒U型影响,港澳台投资发挥着正U型作用,外资存在正向的线性影响;区域异质性分析发现上游制造业集聚与能源环境效率存在正U型关系,中游制造业集聚与能源环境效率存在倒U型关系,下游制造业集聚对能源环境效率不存在显著的影响。

Actively promoting multiple investment and financing mechanisms and rationally distributing manufacturing agglomerations are particularly important for building a pioneer area for ecological protection and high-quality development in the Yellow River basin.Under the premise of considering the ecological environment carrying capacity,the non-radial directional distance function is applied to measure the energy and environmental efficiency of the Yellow River basin from 2006 to 2021,and the non-linear impact of manufacturing agglomeration on energy and environmental efficiency is investigated through the spatial Tobit Durbin model,as well as the role of heterogeneous investment is explored.The results show that manufacturing agglomeration has an inverted U-shape effect on energy environmental efficiency,and manufacturing agglomeration in neighbouring places has a positive U-shape spillover effect on local energy environmental efficiency;the mechanism analysis shows that there is an inverted Ushape effect of domestic investment,Hong Kong,Macao and Taiwan investment plays a positive U-shape role,and there is a positive linear effect of foreign investment;the regional heterogeneity analysis reveals that there is a positive U-shape relationship between the upstream manufacturing agglomeration and energy environmental efficiency,and there is a positive U-shape relationship between the midstream manufacturing The analysis of regional heterogeneity finds that there is a positive U-shaped relationship between upstream manufacturing agglomeration and energy environmental efficiency,an inverted U-shaped relationship between midstream manufacturing agglomeration and energy environmental efficiency,and no significant effect of downstream manufacturing agglomeration on energy environmental efficiency.
