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 scientific measurement of cultivated land protection externalities in grain-production-dominated zones is an important basis of the regional and interregional economic compensation standard of cultivated land protection. At the same time it is also a key link for the construction of economic compensation mechanisms of cultivated land protection. The cultivated land protection externalities boundary of grain-production dominated zone is related to the scale of the research field,which affects the measurement and segmentation of externalities. Therefore,in this study,a concept model of multi-level boundary with respect to cultivated land protection externalities in grain-production-dominated zones is proposed. Based on this,the measurement method and model of cultivated land protection externalities and its external multi-level boundary are constructed. Three typical grain-production dominated counties:Taikang County (Zhoukou)in Huanghuaihai Plain,Tanghe County (Nanyang)in Nanyang Basin and Wen County (Jiaozuo)in the north and western piedmont plain of Henan province were selected as study sites. Externalities and scale effects of each these counties were measured and analyzed under prefectural and provincial boundaries. We found that the externalities of cultivated land protection in grain-production dominated zone have multi-level boundary characteristics. The boundary can be a natural boundary line (watershed boundaries,etc.)and also can be a social-economic boundary line (administrative boundaries)as well. There are significant temporal-spatial differences of the externalities between theoretical value and realistic value under the actions of boundary scales variations. These differences will affect the criteria of economic compensation per unit for cultivated land protection and the strength of inter-regionally fiscal transfer payments. A dynamic multi-level compensation system needs to be established based on the regulation of superior government and fiscal transfer payments in light of temporal-spatial variations in externalities.
