【摘要】：城市化快速发展的同时,每天巨大的生活垃圾产生量也在不断地侵蚀着城市,生活垃圾处理能力短缺问题日渐突出,这对城市环境构成严峻挑战。净菜进城能有效地减少城市生活垃圾,为城市生活垃圾“瘦身”。对一些发达国家,如日本,欧美等现在净菜市场率已高达80%以上。我国净菜产业发展相对较晚,净菜供应链的建设、发展都还处于初级阶段,供应链系统中存在诸多问题。如何使净菜供应链能够有效实施,保障供应链的发展,最大限度地减少城市生活垃圾已成为一个值得研究的问题。主要研究内容有:第一,在前人研究的基础上整理出本文对净菜、净菜供应链的定义,阐述其特点,详细分析了净菜供应链涉及到的主体以及他们之间的关系。第二,通过发放净菜市场调查问卷,分析制约消费者购买净菜的主要因素以及净菜市场存在的问题。调查结果显示:制约消费者购买净菜的因素主要是净菜质量安全因素,净菜市场存在的问题是净菜加工行业比较薄弱,缺乏竞争力。第三,针对净菜质量安全投入问题,提出演化博弈理论和方法,根据农户收益的不同划分为三种情况,研究风险规避型农户和风险中性型净菜加工商三种情况下长期的质量投入策略。研究表明:在市场机制下,三种情况均不能保证农户和净菜加工商进行质量投入,需要政府采取一定的措施,对进行净菜质量投入的主体实施补贴提高其进行质量投入的积极性。第四,针对我国净菜加工行业比较薄弱的问题,本文建立了净菜加工商和餐饮企业组成的两级供应链演化博弈模型,得出在市场机制下,净菜供应链主体长期的策略选择具有不确定性。因此,政府有必要介入净菜供应链,政府可以通过三种有效措施促使净菜供应链在长期中发展。
[Abstract]:With the rapid development of urbanization, the huge amount of domestic waste is eroding the city every day, and the shortage of domestic waste disposal capacity is becoming more and more serious. This poses a serious challenge to the urban environment. Net food entering cities can effectively reduce urban domestic waste and "reduce the size" of urban domestic waste. For some developed countries, such as Japan, The net vegetable market rate in Europe and the United States has now reached more than 80%. China's net vegetable industry has developed relatively late, and the construction and development of the net vegetable supply chain are still in the initial stage. There are many problems in the supply chain system. How to make the net vegetable supply chain implement effectively, ensure the development of the supply chain and minimize the municipal solid waste has become a problem worth studying. The main research contents are as follows: first, On the basis of the previous studies, this paper sorted out the definition of the net vegetable supply chain, elaborated its characteristics, analyzed the main bodies involved in the net vegetable supply chain and their relationships in detail. Secondly, by issuing the net vegetable market questionnaire, This paper analyzes the main factors restricting consumers' purchasing of clean vegetables and the problems existing in the market of net vegetables. The results show that the factors restricting consumers' purchasing of net vegetables are mainly the quality and safety factors of net vegetables. The problem in the net vegetable market is that the net vegetable processing industry is weak and lack of competitiveness. Thirdly, the evolutionary game theory and method are put forward to solve the problem of the quality and safety input of the net vegetable, which can be divided into three situations according to the different income of the farmers. The long-term quality investment strategies of risk-averse farmers and risk-neutral vegetable processors are studied. The results show that under the market mechanism, the quality input of farmers and vegetable processors is not guaranteed. It is necessary for the government to take certain measures to subsidize the main bodies engaged in the quality investment of clean vegetables to improve their enthusiasm for quality investment. 4th, aiming at the relatively weak problems in the processing industry of clean vegetables in China, In this paper, a two-level supply chain evolutionary game model composed of vegetable processors and catering enterprises is established, and it is concluded that under the market mechanism, the long-term strategic choice of the main body of the net vegetable supply chain is uncertain. Therefore, it is necessary for the government to intervene in the net vegetable supply chain. The government can use three effective measures to promote the long-term development of the net vegetable supply chain.
