摘要
基于财政分权视角,利用2000—2019年中国31个省市(不计港澳台地区)的面板数据,运用空间杜宾模型和门槛模型,探究财政分权对农业面源污染的空间溢出效应及不同经济发展水平下财政分权对农业面源污染的门槛特征。研究发现:财政分权度的提高不仅会加剧本地区农业面源污染,而且对邻近地区的农业面源污染存在恶化作用,具有明显的空间溢出效应。同时,财政分权与农业面源污染之间存在经济发展水平的单一门槛效应。当经济发展水平较低时,财政分权对农业面源污染存在显著的恶化效应;跨过门槛值后,财政分权对农业面源污染的增污效应明显减弱。基于以上研究结论,建议加强地方政府的联动治理、加快经济高质量发展以及完善“环境保护”型的政绩考核体系。
Based on the perspective of fiscal decentralization,using panel data of 31 Chinese provinces and cities from 2000-2019,and employing the spatial Durbin model and threshold model,the study explores the spatial spillover effect of fiscal decentralization on agricultural surface source pollution and the threshold characteristics of fiscal decentralization on agricultural surface source pollution under different economic development levels.It is found that the increase of fiscal decentralization not only aggravates agricultural surface source pollution in the region,but also has a worsening effect on agricultural surface source pollution in the neighboring regions,with obvious spatial spillover effects.Meanwhile,there is a single threshold effect of economic development level between fiscal decentralization and agricultural surface source pollution.When the economic development level is low,there is a significant worsening effect of fiscal decentralization on agricultural surface source pollution;after crossing the threshold,the pollution-increasing effect of fiscal decentralization on agricultural surface source pollution is significantly weakened.Based on the above findings,it is recommended to strengthen the linkage governance of local governments,accelerate high-quality economic development,and improve the performance assessment system of"environmental protection".
