摘要
以2013—2022年我国中部H省的12个地市为研究对象,采用空间动态杜宾模型,对H省城市绿色发展效率与环境规制进行了研究。空间相关性检验表明,H省12地市绿色发展效率有显著局域空间集聚特征存在,绿色发展效率低的被同为水平低单元包围、绿色发展效率高的被同为高水平单元包围的现象比较明显。Moran’s I显示自2019年以后,H省各地市绿色发展效率的空间集聚特征显著。根据Moran散点图可以看出,多数地市表现出从“低-高”“高-低”聚集向“高-高”“低-低”聚集的绿色发展效率趋势。根据空间溢出效应来看,在短期内提升环境规制强度,会有效提高“经济相邻”地区绿色发展效率。同时绿色发展效率会随着长期内环境规制强度的提高而提高,但未表现出显著的直接和间接效应。
Taking 12 cities in H Province in central China from 2013 to 2022 as research objects,this paper studies the efficiency of urban green development and environmental regulation in H Province by using the spatial dynamic Durbin model.The spatial correlation test showed that the green development efficiency of 12 cities in H province had a significant local spatial agglomeration feature,and the phenomenon of low green development efficiency surrounded by low-level units and high green development efficiency surrounded by high-level units was more obvious.Moran's I showed that since 2019,the spatial agglomeration characteristics of green development efficiency of cities in H Province have been significant.According to the Moran scatter chart,it could be seen that most cities showed a trend of green development efficiency from"low-high"and"high-low"clustering to"high-high"and"low-low"clustering.According to the spatial spillover effect,improving the intensity of environmental regulations in the short term would effectively improve the green development efficiency of"economically adjacent"areas.At the same time,green development efficiency will increase with the increase of environmental regulation intensity in the long run,without significant direct or indirect effects.
