Study on Evaluation Index System of Green Supply Chain for Automobile Products

Introduction

The automobile industry plays an important role in promoting China's economic growth. In recent years, the automobile industry has always maintained a stable development trend. At present, in the global automotive industry, the rapid growth of automotive production and sales brings convenience to our life, while the contradiction between automotive industry and environment, resources and so on is becoming increasingly prominent. The “life cycle” green supply chain is the only way for the development of the automotive industry Lertwongsatien, 2000). It considers environmental factors on the basis of the traditional supply chain, so as to reduce environmental pollution and waste of resources throughout the life cycle of automotive products. Therefore, based on the principle of “green development, sustainable development, and life cycle”, the author establishes a feasible, scientific and reasonable evaluation index system for the green supply chain of automobile products, which is the prerequisite for achieving social and economic benefits and the inevitable requirement of sustainable development (Luken et al. 2008).

In the early days, the concept of “supply chain” has become the focus of scholars from all walks of life. With the advent of the “green era”, the green supply chain has increasingly become the focus of attention, and the former “supply chain” is naturally defined as “traditional supply chain”. There are many studies on the evaluation system of the traditional supply chain at home and abroad. The classical models include the SCOR model abroad and the SCOR model at home. In 1996, the International Supply Chain Association (ISA) put forward the SCOR model, which provides a model basis for the evaluation of the supply chain in the automotive industry. This model mainly constructs the index system of the supply chain from four aspects: turnover period, cost, service, and assets. In 2013, China put forward the SCPR model. SCPR model combines the advantages of various performance models and is suitable for Chinese enterprises. This mode Type I is mainly embodied in order completion, customer satisfaction, team collaboration, node network efficiency, and business adaptability. In order to promote green development, green management and green performance evaluation of automobile supply chain have become a hot spot. In recent years, the research on the green supply chain of automobiles has been common. Domestic and foreign scholars' research on the green supply chain of automobiles is scattered. Most of them choose to add environmental or green factors from one of the links of green design, green procurement, green production, green sales, and green recycling. Zhu Xuhui (2014) explored the inevitability of green design in the automobile industry from the theoretical source, based on the strategy and benefits of green design, and Ma Huanhuan (2016) took green procurement as the starting point to study the selection of suppliers in automobile manufacturing enterprises. Based on the construction of supplier evaluation index system, taking L Company as an example, the TOPSIS comprehensive evaluation model is used to make an empirical analysis on the selection of suppliers of automotive engines. Li Weiming (2016) based on the green recycling and remanufacturing system, analyzed the influencing factors of recycling behavior, took the waste automobile as an example, constructed the green system dynamics model, from the essence of the model, based on population, resources, environment, and other factors, excavated the green factors of the whole recycling system.

Generally speaking, there are many studies on the evaluation index system of automobiles worldwide. The contents of the research are constantly enriched and the research methods are becoming more and more mature. However, domestic and foreign scholars in the green supply chain evaluation, the research angle is relatively single, the index system is not complete. Most scholars only analyze the process of purchasing, producing and recycling automotive products. It is difficult for “green index” to reflect the environmental performance in an all-round way. Even though green consumption has become the public's consumption concept and green development has risen to the national level, green supply chain management has not really been implemented. Therefore, drawing lessons from the existing research results, starting from the “life cycle” of products, the author aims to build a set of “life cycle” green index system, as a value evaluation system for enterprises to achieve green development, and to seek the optimal path to achieve sustainable development of the automotive industry, with a view to making the whole of automotive products. The life cycle is “green” to achieve a win-win situation between economy and environment.
