Research On Circular Economy Efficiency And Influence Factors Of Liaoning’s Manufacturing

Manufacturing industry is the basic industry in our country, which has made outstanding contributions for the economy development and modernization. Manufacturing industry has become an important symbol to measure the core competitiveness of a country. In the past three decades, Chinese manufacturing industry has made considerable development, a variety of manufacturing products output ranked first in the world. And Liaoning, as the eldest son of the Republic of China, has been the big manufacturing industry province since the foundation of China, the manufacturing sector has played an irreplaceable role in the national economy of Liaoning. Although manufacturing account for large share of GDP, it still has very large development space for the technical strength and development level of manufacturing. Liaoning manufacturing industry is mainly based on extensive growth mode, weak independent research capacity, low technical level, weak comprehensive competitiveness. Especially in recent years, Liaoning economic growth continued to slow down, downward pressure increased, while manufacturing output has accounted for a larger proportion of the national economy, so the sustained downturn of manufacturing has become the main reason for restricting economic growth in Liaoning. At the same time, a long period of the overexploitation has made many cities in Liaoning face the plight of resource depletion. In the background of rapid increase for resource, the problem of insufficient supply gradually highlight, which brings greater difficulties for the manufacturing, and the sustainable development of Liaoning manufacturing industry is facing enormous challenges. Therefore, not only should we focus on the development of enterprises, improve the yield and efficiency of creation, but also pay attention to save resources use efficiently and protect the environment. As a new economic development model, circular economy has completely different characteristics from the traditional linear economy, is an effective way to achieve the above requirements.This paper is divided into the following four parts:The first part is the introduction and theoretical basis determined, including the first chapter and the second chapter of theoretical basis. The first chapter is the introduction, mainly introduced research background and topic significance, arranging and assessing the research of circular economy efficiency from home and abroad. Find the shortcoming of the existing research and then raise the main problems in the text. The second chapter is the outline and theoretical basis of the circular economy. First defined the basic concept of circular economy and circular economy efficiency. And then introduced the theoretical base of circular economy from management economics, ecology, environmental science. Define the research object and scope of this study.The second part is the development status description of manufacturing industry in Liaoning Province, in the Chapter Ⅲ. The third chapter analyzed the status and spatial distribution of manufacturing industry manufacturing industry, followed by the analysis of development status of the circular economy in manufacturing, and introduced manufacturing circular economy practice from the business, industrial parks and industry. Finally, analyzed the economic indicators, environment and recycling use indicators of manufacturing economy in Liaoning.The third part is the empirical research of efficiency evaluation and its influencing factors of Liaoning Province manufacturing cycle economy, including the fourth chapter, Chapters Ⅴ and Ⅵ. To construct manufacturing industry circular economy efficiency evaluation indicator system, use DEA to evaluate Liaoning Province 14 prefecture-level cities circular economy efficiency and analyze the dynamic change trend. Chapter V used input-output techniques to build circular economy input-output table to analyze the circular economy efficiency of manufacturing sectors in Liaoning Province. The sixth chapter is the analysis of Liaoning Province manufacturing circular economy efficiency influencing factors. Based on efficiency analysis, use Tobit to regression analyze panel data, and find out the main reasons of influencing manufacturing circular economy efficiency.The fourth part is the main conclusion and the policy suggestions of this paper, in the seventh Chapter. The seventh chapter is the conclusion to summarize the main conclusion.On the basis of empirical research, based on the conclusions, put forward the countermeasure to promote circular economy of manufacturing in Liaoning Province.The study found that there is much improvement in overall efficiency level of Liaoning Province manufacturing circular economy. The gap among each cities in the province is obvious. Shenyang, Dalian, Fuxin and other places manufacturing circular economy efficiency are ranking, Chaoyang, Tieling and Dandong manufacturing circular economy efficiency are a little poor. From the view of changes in circular economy efficiency, the promotion of Liaoning Province manufacturing circular economy is mainly due to the technology improvement and comprehensive technical efficiency promotion, the manufacturing circular economy efficiency differences in Liaoning exist absoluteβ-convergence, which takes about 15 years for circular economy efficiency to reach the same steady circulation growth. Circular economy efficiency in Liaoning is low-ranking in the country, especially has a larger gap with other circular economy pilot provinces. Circular economy efficiency indicators in manufacturing sectors has significant improvement between 2002 and 2012. The coefficient of energy consumption per unit of output and Pollutant discharge coefficient in metal smelting, chemical products, petroleum, non-metallic mineral products and other departments are very large, while wastewater discharge coefficient in textile industry and printing sector is the biggest. Furthermore, the emission factor in communication device and other manufacturing sectors has a certain degree of rise. The study found technology improvement of manufacturing, comprehensive technical efficiency, foreign trade and the proportion of tertiary industry have a positive impact on manufacturing circular economy efficiency, and the regional economy development level has the biggest impact on manufacturing circular economy. While the proportion of state-owned economy has negative impact on it, Population density and government intervention failed to pass the test of significance.
