基于土地社会保障功能的区域土地整理社会效益测算研究——以南京市为例(英文)

Social Benefit Evaluation on Regional Land Consolidation Based on Social Security Function of Land——A Case of Nanjing City

概述了农地社会保障功能,主要有3方面内容:土地收入能提供养老保障;土地能起到失业保险的作用;土地能满足绝大多数农民的基本生存需要。分析了土地整理对农地保障功能的增强作用,介绍了构建土地整理社会保障功能价值模型的思路,将人口划分为被抚养人口、基本人口和保养人口3种类型,并提出了养老保障、医疗保障、失业保障等主要土地整理社会保障功能价值的定量测算方法。土地整理养老保障价值主要涉及基本人口和保养人口;土地整理医疗保障价值和失业保障价值主要涉及被抚养人口和基本人口。以中国江苏省南京市为例,根据1999～2005年土地整理增加的有效耕地面积和原有耕地增产情况,分别计算了土地整理对基本人口、被抚养人口、保养人口的养老保障、医疗保障和失业保障等社会保障功能价值。研究表明:1999～2005年,江苏省土地整理社会保障总价值可达39.46亿元,是土地整理项目投资总额的7.65倍,土地整理的社会效益显著;养老保障价值仍是社会保障功能价值的核心,占63. 74%,这与当前土地的社会保障功能核心吻合;随着经济的发展,医疗保障和失业保障的作用也越来越显重要。

Quantitative method for social benefit evaluation on land consolidation is put forward based on social security function of land.It has broken through the limitation of current social benefit evaluation on land consolidation,which can only carry out qualitative assessment.Social security of land consolidation includes three aspects of the old-age security,medical security and unemployment security.Functional values of social security,such as the old-age security,medical security and unemployment security,for three types of population(basic population,dependent population and maintenance population)are calculated according to the effective area and original production of arable land.Research result shows that the implementation of land consolidation has brought substantial social benefits.The value of old-age security is still the core,meanwhile the functions of medical security and unemployment security become more and more significant.Quantitative estimation on land consolidation benefits has important function and guiding value on evaluating the effectiveness of land consolidation project and on decision making of investment.
