生态产业链、利益主体异质性与畜禽污染治理：机理与制度设计

Establishing eco-industry chain of livestock pollution control while all related interest stakeholders taking parts in is an effective solution to reduce livestock pollution and excessive fertilizer use, increase farmers' income and achieve green development of agriculture. Eco-industry chain is becoming the innovative direction of livestock pollution control in the future. The main goal of our proposed study is to analyze livestock pollution control, under the perspective of eco-industry chain and heterogeneities of the interest stakeholders, to help policy makers design effective and efficient livestock pollution control policies. .To achieve this goal, this study will utilize multi-disciplinary methods and survey data from a large-scaled household sample. Firstly, multivariable probit model, gambling experiment and the choice experiment methods will be applied to explore the mechanism of heterogeneous livestock farmers’ and growers’ livestock pollution control behavior and their preference for livestock pollution control policy. Secondly, participatory rural appraisal evaluations and qualitative methods will be employed to understand the mechanism of third party’ livestock pollution control behavior and their preference for livestock pollution control policy. Furthermore, we will also examine the cooperation behavior among different interest stakeholders in the eco-industry chain and their influencing factors, while implementing the hierarchical linear and the multinomial logit models. .As a result of our project, we will supply policy recommendations for the establishment and refining of the livestock pollution control eco-industry chain. These findings would provide scientific political evidences for the Chinese government in order to establish circular mechanism in the livestock industry which has been emphasized in the No. 1 document in 2016, as “to promote the development of agriculture and animal husbandry, breeding combined cycle” and to promote synergetic governance systems of environmental pollution control.

实施利益主体共同参与的畜禽污染生态产业链治理对减少畜禽污染、降低化肥使用、提高农民收入及实现农业绿色发展具有重要作用，是畜禽污染治理理论与实践的创新方向。本课题将突破当前单一主体的畜禽污染治理政策和传统经济学的同质性假设，从生态产业链和利益主体异质性视角研究畜禽污染治理问题。首先，以多变量Probit模型、赌博实验和选择实验方法解析不同类型养殖户和种植户畜禽污染生态产业链治理行为机理及政策需求；其次，采用参与式农村评估和质性分析方法厘清不同类型第三方治理主体畜禽污染生态产业链治理行为机理及政策需求；再次，运用分层线性和多元选择模型分析畜禽污染生态产业链治理不同利益主体的合作机理及利益协调机制，探讨畜禽污染生态产业链治理模式的可持续性。研究结论可为2016年中央一号文件提出的“推动种养结合、农牧循环发展”及当前生态文明体制改革背景下环境污染多元共治体系的构建提供理论基础和政策建议。

考虑畜禽污染的可循环利用特性，实施利益主体共同参与的畜禽污染生态产业链治理是新时期我国畜禽污染治理理论与实践的创新方向。本项目将突破当前单一主体的畜禽污染治理政策和传统经济学的同质性假设，从生态产业链和利益主体异质性这一全新的视角来重新审视畜禽污染治理问题。本项目重点研究了以下内容：（1）采用双变量Probit模型分析了大规模和小规模种植户畜禽污染生态产业链治理行为及其形成机理。（2）采用随机干预实验方法分析了农业技术培训对种植户畜禽污染生态产业链治理行为的影响。（3）应用扎根理论方法分析了种植户畜禽养殖废弃物循环利用的政策需求及政策干预路径。（4）基于多变量Probit模型分析了规模化养殖户畜禽污染治理行为的影响因素，并进一步分析了养殖户畜禽污染治理意愿与行为一致性的决定因素。（5）采用选择实验方法分析了不同规模养殖户以及养殖企业对畜禽污染治理政策的需求。（6）采用OLS模型和泊松回归模型分析了我国采纳畜禽污染政府与社会资本合作治理模式的影响因素。（7）基于大数据技术分析了1978年以来我国畜禽污染治理政策的演进特征。..以这些研究为基础，项目取得如下成果：（1）发表学术论文30篇，其SSCI/SCI检索期刊论文15篇，CSSCI/CSCD论文9篇。出版学术专著2部。项目主持人被评为经济学领域“中国哲学社会科学最有影响力学者”。（2）获得各项奖励14项，其中省级社会科学优秀成果一等奖1项和三等奖2项，国家一级学会学术奖励1项。（3）撰写并提交了政策咨询报告8份，获省委书记等省级领导批示6次。（4）举办国际性学术会议1次，全国性学术会议4次，参加国内外学术交流14次，邀请国内著名学者做专题讲座11人次。（5）累计带动培养毕业硕士生6人，毕业博士生1人，在读硕士生4人。项目主持人获批为第四批国家“万人计划”青年拔尖人才，江西省“百千万人才工程”人选等人才称号。
