【摘要】：粮食主产区外部性边界的选取影响着耕地保护外部性测度及其区内区际外部性分割。本文基于外部性多层次边界视角,提出了粮食主产区耕地保护外部性多层次作用边界概念模型,构建了耕地保护外部性量化方法和模型。并在河南省粮食主产区黄淮海平原、南阳盆地和豫北豫西山前平原三大区域内选取周口市太康县、南阳市唐河县和焦作市温县3个典型粮食主产县作为实证区域,纳入相应市域和省域进行不同作用边界下的外部性量化和尺度效应分析。结果表明:1粮食主产区耕地保护外部性具有多层次作用边界特征,该边界可以是具有自然特征的边界线(如流域边界等),也可以是具有社会经济特征的边界线(如行政区划界);2不同尺度外部性作用边界下粮食主产区耕地保护外部性理论值和现实值存在显著的时空差异性,该差异性影响着单位面积耕地保护经济补偿标准高低和区域间财政转移支付力度;3应依据不同作用边界下耕地保护外部性时空差异性,建立基于上级政府调控和财政转移支付的全国-省-市-县多层次一体化的动态耕地保护经济补偿体系。
[Abstract]:The selection of the external boundary in the main grain producing areas affects the measure of the externality of cultivated land protection and the partition of the inter-regional externalities. This paper is based on the multi-level boundary perspective of the externality. The concept model of the externality of cultivated land protection in the main grain-producing area is put forward, and the quantification method and model of the externality of cultivated land protection are constructed, and it is found in the Huang-Huai-Hai plain of the main grain-producing area of Henan Province. In the three regions of the Nanyang Basin and the Piedmont Plain of the West Henan Province, three typical grain producing counties of Zhoukou City, Tanghe County and Wenxian County of Jiaozuo City are selected as the demonstration regions. The results show that the externality of cultivated land protection in the main grain-producing area of 1 / 1 has the characteristics of multi-level function boundary. The boundary can be a boundary line with natural characteristics (such as watershed boundary, etc.) or a boundary line with social and economic characteristics (such as administrative boundaries); (2) there are significant spatio-temporal differences between the theoretical and practical values of cultivated land protection externality in the main grain producing areas under the boundary of externality of different scales. The difference affects the standard of economic compensation for the protection of cultivated land per unit area and the intensity of inter-regional financial transfer payment. (3) according to the externality of cultivated land protection under different function boundaries, the dynamic economic compensation system of cultivated land protection should be established based on the regulation and control of higher government and the transfer payment of finance, which is based on the multi-level integration of the whole country, province, city and county.
