【摘要】：文章运用PSTR模型和城市动态面板数据,实证发现中国城镇化对水资源利用总量的影响是非线性的,该影响依赖于各转换变量,且均存在门槛效应。其中,对于经济发展水平较高城市与较低城市,城镇化对水资源利用总量的提高作用均较小,对于中等经济发展水平城市,城镇化对水资源利用总量的提高作用较大。该结论也适用于对外贸易和外资两个转换变量;其他转换变量则将各城市分为高低两个体制,其中产业结构水平较高的城市的城镇化降低了水资源利用总量,产业结构水平较低的城市城镇化提高了水资源利用总量;技术进步、要素集聚程度和人力资本水平越高的城市,城镇化对水资源利用总量的降低作用越大;要素市场扭曲程度越高的城市,城镇化对水资源利用总量的提高作用越大。
[Abstract]:By using PSTR model and urban dynamic panel data, it is found that the impact of urbanization on the total water resources utilization is nonlinear, which depends on the conversion variables and has a threshold effect.For the cities with higher economic development level and lower cities, urbanization has little effect on the total utilization of water resources, and urbanization plays a greater role on the total utilization of water resources for cities with medium economic development level.The conclusion is also applicable to the foreign trade and foreign capital conversion variables, while other conversion variables divide the cities into two systems, in which the urbanization of the cities with higher industrial structure reduces the total amount of water resources utilization.The cities with low industrial structure increase the total utilization of water resources, and the cities with higher concentration of factors and human capital have greater effect on the reduction of total water resources utilization.The higher the distortion of factor market, the greater the effect of urbanization on the total utilization of water resources.
