我国农地产权代际补偿基金的代际分配问题研究

RESEARCH ON THE INTERGENERATIONAL DISTRIBUTION ISSUE OF THE INTERGENERATIONAL COMPENSATION FUND OF FARMLAND PROPERTY RIGHT IN CHINA

[目的]文章提出农地资源代际补偿技术手段,探索适合国情的农地产权代际补偿基金模式,解决基金代际分配的定量分析问题,提升我国农地征收补偿公平政策制定的科学化水平。[方法]从外部性理论视角对农地功能价值属性重新归类,经济与生态属性价格叠加构成农地直接产品价格,通过农地直接产品价格形成农地产权价格。纳入代际公平因素,建立替代现行土地征收价格制度的农地产权代际补偿基金,基金资金主要由农地产权价格形成,全面体现当代人与后代人的产权利益。借助Diamond模型,构建农地产权价格代际分配公式,模拟农地征收后产权价格在当代人与后代人之间分配的决策行为。运用脱钩理论作为产权价格分配公式中代内消费倾向θ变量选取的理论依据,采用Tapio弹性系数法对θ值进行模拟,预测当代人与后代人之间的土地产权价格分配,以四川省乐至县为例进行具体实证计算。[结果]乐至县单位农地面积的产权价格是1583.35万元/hm 2,预测出当代人30年以内分得的土地价格是791.67万元/hm 2,后代人支配剩余土地价格791.67万元/hm 2。[结论]经济与生态属性价格叠加的农地直接产品价格是农地产权代际补偿基金主要资金来源,基金可有效解决农地征收产权价格问题,体现当代人与后代人的共同产权利益;Diamond模型可模拟农地征收产权价格在当代与后代人之间的分配决策行为,经预测:伴随农民收入增加,代内消费倾向θ呈现逐步减少的趋势,代际支付意愿增加,当代人与后代人趋向对农地产权价格的均分。

This research is intended to propose the technical methods of intergenerational compensation for farmland resources,explore the intergenerational compensation fund model of farmland property right suitable for national conditions,and promote the scientific level of formulating fair policies for farmland expropriation compensation in China.From the perspective of externality theory,the functional value attributes of farmland were reclassified in this research,and the direct product price of farmland was superimposed by the economic and ecological attribute prices,which came into being the property price of farmland.By incorporating intergenerational equity factors,an intergenerational compensation fund for farmland property rights that replaced the current land expropriation system was established.This fund was mainly formed by the price of farmland property rights,which fully reflected the property rights of current and future generations.Furthermore,the intergenerational distribution formula of farmland property right was constructed by the Diamond model to simulate the decision-making behavior of property rights prices between contemporary and future generations after farmland expropriation.Besides,the decoupling theory was used as the theoretical basis for selecting the intra-generational consumption propensity variableθin the property rights price distribution formula,and the value ofθwas simulated by Tapio elastic coefficient method to forecast the distribution of farmland property price between current and future generations.This research took Lezhi county in Sichuan province as an example for specific empirical calculations.The results showed that the property price of farmland in Lezhi county was 15.8335 million yuan per hectare,and it was predicted that the price of land shared by contemporary generation within 30 years was 7.9167 million yuan per hectare,and the price of the remaining land for future generations was 7.9167 million yuan per hectare.The direct product price of farmland with the combination of economic and ecological attributes is the main source of funding for intergenerational compensation of farmland property rights,and the fund can effectively solve the problem of the price of farmland expropriation property rights,reflecting the common property rights interests of contemporary people and future generations.The Diamond model can simulate the decision-making behavior of the allocation of farmland expropriation prices between current and future generations.The prediction results show that,as farmers′income increases,the intra-generational consumption propensity variableθdecreases gradually,and the intergenerational willingness to pay increases.Finally,contemporary people and future generations tend to distribute farmland property price evenly.
