【摘要】：秸秆是一种重要的生物质能源,具有很高的资源利用价值,对其有效利用可以从一定程度上缓解现阶段能源需求紧张的现状。但是,现阶段秸秆就地焚烧现象仍然存在,这不仅浪费大量的资源,还会产生相应的经济、社会和环境问题。因此,探讨秸秆就地焚烧的深层次原因,对实现秸秆的资源化利用,具有重要的现实意义。本文采用实证分析与理论分析相结合的方法,对永城市小麦秸秆处置的具体情况进行了分析。本文共分为七个部分:第一部分,主要论述本文的研究背景、研究目的与意义、研究框架、文献综述以及研究的创新与不足。第二部分,相关理论,主要包括供求理论、“经济人”假设、逆向选择与道德风险理论。第三部分,主要论述永城市秸秆处置的现状。第四部分,基于对永城市样本农户的调查数据,采用logit模型对永城市农户秸秆处置行为的意愿进行分析。第五部分,农户秸秆处置的成本与收益分析。第六部分,基于对龙岗镇XX秸秆厂的实际调查,来分析企业秸秆处置的成本与收益。第七部分,研究结论与政策建议。研究结果表明,农户就地焚烧秸秆的意愿仍然强烈,但现阶段秸秆利用所面临的主要问题,是秸秆的随意弃置。秸秆粉碎还田,是目前解决秸秆就地焚烧问题最直接有效的方式,但还田量有限。秸秆利用的中间环节成本与运输成本较高,这些都制约着农户出售秸秆的积极性。最后,从加大政府支持力度,实现农户与企业的直接对接,加强技术研究与创新,加强科普宣传这几个方面提出相应的政策和建议。
[Abstract]:Straw is an important biomass energy, with high resource utilization value, the effective use of straw can alleviate the current situation of energy demand in a certain extent. However, at present, straw burning still exists, which not only wastes a lot of resources, but also brings about the corresponding economic, social and environmental problems. Therefore, it is of great practical significance to probe into the deep causes of straw burning in situ to realize the utilization of straw. In this paper, the concrete situation of wheat straw disposal in Yongcheng city was analyzed by combining empirical analysis with theoretical analysis. This paper is divided into seven parts: the first part mainly discusses the research background, research purpose and significance, research framework, literature review and research innovation and shortcomings. The second part is related theories, including supply and demand theory, economic man hypothesis, adverse selection and moral hazard theory. The third part, mainly discusses the status of Yongcheng straw disposal. In the fourth part, based on the survey data of the sample farmers in Yongcheng City, the logit model is used to analyze the willingness of the farmers to dispose of straw in Yongcheng City. The fifth part, the cost and income analysis of peasant household straw disposal. The sixth part, based on the investigation of XX Straw Plant in Longgang Town, analyzes the cost and benefit of straw disposal. The seventh part, research conclusions and policy recommendations. The results show that the willingness of farmers to burn straw in situ is still strong, but the main problem in straw utilization at present is the random disposal of straw. Straw crushing and returning to field is the most direct and effective way to solve the problem of straw burning in situ, but the amount of return is limited. The intermediate cost and transportation cost of straw utilization are high, which restricts the enthusiasm of farmers to sell straw. Finally, this paper puts forward the corresponding policies and suggestions from the aspects of increasing government support, realizing the direct connection between farmers and enterprises, strengthening technological research and innovation, and strengthening the popularization of science.
