【摘要】：乳业是我国处于快速发展阶段的朝阳产业,乳制品营养成分齐全,已逐渐成为人们日常饮用的重要食品。乳业贯穿畜牧业、制造业和流通业三大产业部门,从原料奶生产到终端用户的供应链长且复杂,在为消费者提供终端产品的同时,也带动了相关产业的发展。近年来,随着人们生活水平的提高和消费观念的转变,乳品销售量逐年提高,此种现象为乳业的发展创造了很好的机会,使得我国乳业得到了极大的发展,市场份额逐年增加,现已成为地方经济中最具活力的产业之一。但是,在发展的过程中,出现了奶源战、价格战和乳制品质量安全等问题,这些问题折射出了乳品供应链运作的无效率,没有充分发挥出供应链应有的优势,使其成为了我国乳业发展的瓶颈。因此,找出致使乳品供应链低效率的根源,提出相应的解决方案,对于促进我国乳业健康可持续发展具有重要的政策意义。为此,本文对乳品供应链的效率进行了深入的研究,针对现有研究中对乳品供应链以及供应链效率问题的探讨主要集中在定性分析方面的现状,在对供应链基础知识、效率评价方法、DEA方法的理论背景和乳品供应链各阶段的现状进行系统阐述的基础上,考虑到乳品供应链结构的特殊性,设计出了一套由原料奶生产阶段和乳制品加工阶段组成的两级乳品供应链效率评价的指标体系,并且引入网络数据包络分析(网络DEA)建模的方法构建出了两级乳品供应链效率评价模型,以及对两级乳品供应链进行有效DEA前沿面的推导,均以我国31个省(自治区、直辖市)的两级乳品供应链为研究对象进行实证分析或检验,通过演算的结果和对照研究,找出供应链低效率的原因和改进方向,并且提出改进我国两级乳品供应链效率的政策与建议。
[Abstract]:Dairy industry is a sunrise industry in the stage of rapid development in China. Dairy products with complete nutritional components have gradually become an important food for people to drink. Dairy industry runs through animal husbandry, manufacturing industry and circulation industry. The supply chain from raw milk production to end-user is long and complex, which not only provides end products for consumers, but also promotes the development of related industries. In recent years, with the improvement of people's living standard and the change of consumption concept, the dairy sales volume has been increasing year by year. This phenomenon has created a good opportunity for the development of dairy industry, which makes the dairy industry of our country get great development, and the market share increases year by year. It has become one of the most dynamic industries in the local economy. However, in the process of development, there are problems such as milk source war, price war and dairy product quality and safety. These problems reflect the inefficiency of dairy supply chain operation, and do not give full play to the advantages of supply chain. It has become the bottleneck of the development of dairy industry in China. Therefore, it is of great policy significance to find out the causes of the inefficiency of dairy supply chain and put forward the corresponding solutions to promote the healthy and sustainable development of dairy industry in China. Therefore, this paper makes a deep research on the efficiency of dairy supply chain, focusing on the present situation of qualitative analysis and the basic knowledge of supply chain, aiming at the existing research on dairy supply chain and supply chain efficiency. The efficiency evaluation method, the theoretical background of DEA method and the current situation of dairy supply chain are systematically expounded, considering the particularity of dairy supply chain structure. An index system for evaluating the efficiency of a two-level dairy supply chain is designed, which is composed of raw milk production stage and dairy processing stage. The efficiency evaluation model of two-level dairy supply chain is constructed by introducing network data envelopment analysis (DEA) modeling method, and the efficient DEA frontier derivation of two-level dairy supply chain is derived from 31 provinces (autonomous regions) in China. The two-level dairy supply chain of the municipality directly under the Central Government is the research object to carry on the empirical analysis or the test, through the calculation result and the contrast research, finds out the supply chain low efficiency reason and the improvement direction, And put forward the policy and suggestion to improve the efficiency of two-level dairy supply chain in our country.
