【摘要】：作为一种典型的绿色生产方式,秸秆还田兼具环境污染治理与资源循环利用之效,但现实中农户响应并不积极。个体的意愿选择通常会面临着个人及家庭资本禀赋的约束,为探究农户在秸秆还田问题上是否也面临着相同的境况,本文基于相关理论分析,提出了资本禀赋水平和结构会对农户秸秆还田投资意愿产生作用的假说,利用实地调研数据,运用熵值法和CVM方法对农户的资本禀赋水平和结构、秸秆还田投资意愿与水平进行了评价分析,以Probit和Tobit模型实证检验了资本禀赋及其结构对农户秸秆还田投资意愿的影响效应。结果表明:(1)农户的资本禀赋水平存在较大差异,各类资本禀赋按照水平排序为:社会资本(97.99)自然资本(95.42)物质资本(94.88)经济资本(94.23)人力资本(90.01),结构方面以社会资本占优型农户居多,占比40.49%,人力资本占优型的农户个数为0。(2)仅有35.26%的农户愿意投资秸秆还田,但投资意愿水平分布较为均衡,平均投资意愿约为5.62—15.94元/666.7m2·季。(3)自然资本(地形)、物质资本(家电数量)、人力资本(性别比例)、经济资本(收入稳定性和融资能力)和社会资本(制度信任)等水平的提升以及资本禀赋结构的优化均被证明可显著增强农户秸秆还田的投资意愿,可见农户秸秆还田投资意愿不高或因资本禀赋约束所致。由此提出了加强农户资本禀赋积累,优化农户资本禀赋结构的政策建议,以促进秸秆还田等绿色生产方式的推广应用。
[Abstract]:As a typical green production mode, straw returning to the field has both the effect of environmental pollution control and resource recycling, but farmers' response is not positive in reality. The choice of individual will usually face the constraints of individual and family capital endowment. In order to explore whether farmers are facing the same situation on straw return, this paper based on the relevant theoretical analysis. This paper puts forward the hypothesis that the level and structure of capital endowment will play a role in the willingness of farmers to return straw to the field, and applies the field investigation data, entropy method and CVM method to the level and structure of capital endowment of farmers. Based on Probit and Tobit models, the effects of capital endowment and its structure on farmers' willingness to return straw to farmland were tested. The results show that there are great differences in the capital endowment level of peasant households. The order of capital endowments is: social capital 97.99) natural capital 95.42) material capital 94.88) economic capital 94.23) human capital 90.010.The structure is dominated by social capital. Only 35.26% of the farmers are willing to invest straw to return to the field, but the level of investment willingness distribution is more balanced, the proportion of the farmers is 40.49%, the number of farmers with the dominant human capital is 0.2%) only 35.26% of the farmers are willing to return straw to the field. The average investment intention is about 5.62-15.94 yuan / 666.7m2) natural capital (terrains, physical capital (quantity of household appliances), human capital (sex ratio), economic capital (income stability and financing ability) and social capital (institutional trust). It has been proved that the improvement of the same level and the optimization of the capital endowment structure can significantly enhance the willingness of the farmers to return the straw to the field. It can be seen that farmers straw investment is not high or because of the constraints of capital endowment. In order to promote the popularization and application of green production methods such as returning straw to farmland, this paper puts forward some policy suggestions on strengthening the accumulation of capital endowment of farmers and optimizing the structure of capital endowment of farmers.
