摘要
本文基于耕地资源价值流失的视角,以劳动价值理论、效用价值理论、外部性理论、可持续发展理论和福利经济学为理论指导,通过构建耕地资源价值体系及其量化模型,并以上海市为例,运用定性分析与定量分析相结合的方法,对上海市耕地资源价值以及因耕地非农化导致的城市化机会成本进行实证研究。结果表明:(1)耕地资源价值包括经济价值、社会价值、生态价值三个部分;(2)2005-2009年上海市耕地资源价值构成中,社会价值所占比重最大,其次是经济价值,生态价值居后;(3)相应地,由于耕地流失导致的城市化机会成本中,社会成本较高,其次为经济成本,再次为生态成本。由此可见,目前耕地资源对保障农民生活、养老、就业以及对于维护社会稳定,保障粮食安全的作用最大。最后,就研究结果进行了讨论并提出建议,旨在为协调城市化发展与耕地保护之间的矛盾提供参考依据。
This research is intended to build a complete value system of cultivated land resource, and choose reasonable assessment methods to estimate the value of cultivated land resource and the opportunity cost of urbanization. Under the guidance of labor value theory, utility value theory, externality theory, sustainable development theory and welfare economics, the paper analyzes the value connotation of cultivated land resource, which includes economic value, social value, and ecology value. Then assessment models are built. Take Shanghai as an example, the value of cultivated land resource and the opportunity cost of urbanization are calculated with the help of qualitative and quantitative analysis. The result is that the social value is the largest, followed by economic value, and finally the ecology value from 2005 to 2009 in Shanghai. Accordingly, in the opportunity cost of urbanization based on the loss of cultivated land resource, the social cost is highest, followed by the economic cost, and finally the ecology cost during the same period. Thus, cultivated land resource is playing an important role in protecting farmers＇ living, employment, pension, and maintaining social stability, as well as food security. Finally, corresponding countermeasures and suggestions to reduce the opportunity cost of urbanization and achieve sustainable use of cultivated land resource are put forward.
