中國水規(guī)制強(qiáng)度的空間分異與節(jié)水減排效應(yīng)研究
[Abstract]:The "water crisis", which is characterized by shortage of water resources, serious water pollution and deterioration of water ecology, has become one of the bottlenecks restricting the sustainable development of social economy. Effective environmental regulation is a feasible way to improve the efficiency of resource utilization, alleviate environmental pollution and improve environmental quality. However, the effect of environmental regulation policy implemented in China in recent years is not satisfactory, and the environmental quality is still deteriorating. The "hitchhiking" behavior of the government on environmental governance and the "race to the bottom" in the formulation of environmental policy make the effect of environmental regulation policy greatly reduced, so it can be seen that there are mutual influences between the environmental governance effect and the environmental policy formulation among provinces. Therefore, this paper focuses on the environmental regulation in the field of water resources, taking the intensity of water regulation as the research object, deeply explores the spatial characteristics of the water regulation intensity and its water-saving and emission reduction effects between provinces in China, and makes the correct water regulation policy. It is of great significance to solve the problem of water crisis. This paper focuses on the core of water regulation intensity, taking the "measure" of water regulation intensity "spatial relevance"-"water-saving emission reduction effect" as the main line. The following three questions are answered: first, what are the characteristics of the spatial distribution of water regulation intensity and its evolution, and whether there is spatial dependence? The second is whether the water regulation intensity subdivided from the water quality and quantity angle has the specificity to the water saving and emission reduction effect. Third, after incorporating the spatial factors, how does the effect of water regulation intensity change on the effect of water-saving and emission reduction? is there a spatial spillover? This paper is based on the data of eight policy documents issued by government departments of 30 provinces (municipalities and autonomous regions) in China since 1978, which have been published by government departments at the provincial (municipal) level and the provincial and municipal levels since 1978, based on the public information search on the Internet. The intensity of water regulation in 30 provinces (municipalities and autonomous regions) of China from 1978 to 2014 was calculated by using the principle of generalized maximum entropy. Thus, three types of water regulation intensity indices are constructed: water regulation comprehensive intensity index (Fp), water regulation comprehensive intensity index (Fq1) and water quality regulation comprehensive intensity index (Fq2), and their water-saving and emission reduction effects are estimated. On this basis, the spatial distribution characteristics, the change trend, the spatial correlation model and the spatial dynamic transition path of three kinds of water regulation intensity indices are analyzed and tested. Finally, the models of water-saving and emission reduction effects of interprovincial water regulation intensity in China are established under the traditional paradigm (without spatial factor) and spatial paradigm (considering spatial factor), and the magnitude of spatial spillover effect of water regulation intensity is compared and analyzed. The main conclusions are as follows: (1) the intensity of interprovincial water regulation in China has significant spatial agglomeration characteristics and spatial path dependence, which is manifested by the positive spatial autocorrelation and the stability of regional spatial relationship. And the development paths of different types of water regulation intensity are both common and different. (2) there is spatial spillover effect of water regulation intensity, and the water saving and emission reduction effect in this area is affected by the water regulation intensity in "neighbor" area. Spatial spillover effect of interprovincial water regulation intensity can promote the overall improvement of water saving and emission reduction in China. (3) improving water regulation intensity can enhance water saving effect and emission reduction effect. The intensity of water-saving effect and emission-reduction effect of different types of water regulation system is obviously different, and the intensity of water quality regulation system under the effect of emission reduction is unique.
