摘要
由人类活动和自然因素综合作用导致的土壤退化已引起全球的日益关注。国内外许多学者从不同的角度对这一问题进行了研究。本文以制度经济学观点为视角,认为制度因素对农户的约束主要作用于两个方面:一是产生不同的激励机制,改变投资的收益效率;二是影响耕作方式及技术选择的客观条件。将农户作为中间媒介体,本文进而就制度因素对土壤退化的影响提出了一个基本研究思路。
Soil degradation induced by human activities together with natural factors has been attracting increasing attention in the world. Many researchers have studied this issue from differentangles. This paper analyzes soil degradation from the view of institutional economics. The authors argue that institutions affect soil degradation by influencing farm households?behaviors. Firstly, institutions influence farm households investing in production. Secondly, institutions determine selection of patterns of farming systems and technologies. A basic research methodology for the study on how institutions influence soil degradation is thus discussed in the paper.
