Research On MF Efficiency Based On Material Flow Theory

According to domestic and overseas experience, the role of material flow(MF) in economy is closely related to MF efficiency. MF efficiency has a great effect on MF industry which plays an important role in national economy. The research on MF efficiency will help to enhance the efficiency of configuration of MF resource, and then provide scientific basis for the development of MF industry. Increasing MF efficiency is a necessary step to achieve sustainable development of economy and to reduce the MF activities'influence on environment. Increasing MF efficiency is essential in the face of global competition.This paper, on basis of MF theory, observes and studies MF efficiency in economic activities. It's supported by literature analysis and field research, and MF theory, system engineering, economics, technological economics and the method of statistical analysis. Considering the practical situation in China, the paper focuses on research of the concept, system structure, metrics and calculation of MF efficiency. Afterwards, the rule and trend of development and the effect factor of MF efficiency are discussed in the paper. At last, via empirical studies on internal and external literature, the paper puts forward measures to improve the MF efficiency, which will provide quantitative support for relative departments'decision.Main achievements of the paper include:(1) Constructing MF efficiency systemThe paper deeply analyzes the concept of MF efficiency and its role in improving the economy and environment from the consideration of the relation among MF, economy and environment. On this basis, it analyzes their coordination and optimization based on positive cycle of MF efficiency. At last, the basic system of MF efficiency is built up, which announces that MF efficiency system consists of MF economic efficiency, MF technological efficiency and MF environmental efficiency. This issue can also be considered from the perspective of the distinction among macroscopic view, madhyamika view and microscopic view, or from the perspective of dynamic and static.(2) Proposing calculating models for MF efficiency metricsAccording to the constructed MF efficiency system, the paper specifies various metrics of MF efficiency, analyze and detail the calculating formulae models as well as all parameters'computing on the basis of the division among MF economic efficiency, MF technological efficiency and MF environmental efficiency.(3) Conducting empirical analysisAs for the application of this paper's theoretical results, three aspects of issues, respectively aimed at MF economic efficiency, MF technological efficiency and MF environmental efficiency, are looked into through empirical analysis. The method is by investigating and analyzing the literature and field, based on the data availability, computing, evaluating, comparing and analyzing the MF efficiency. This paper estimates and compares China and some other countries to announce the theory's practical applicability and development trend of MF efficiency, and then proclaim the development trend of MF economic efficiency, MF input coefficient and MF input coefficient of elasticity. The MF technological efficiency is analyzed and calculated from the angles of enterprise and material. For the MF environmental efficiency, the paper focuses on the negative output produced by energy consumption of MF industry especially transportation business.(4) Analyzing influencing factors of MF efficiency, and proposing measures of improving China MF efficiencyFrom the MF efficiency basic calculating formulas, the paper analyzes the influencing factors of improving MF efficiency, puts forwards that the main means of improving MF efficiency are reducing MF input and strengthening MF management as well as technology. On these grounds, the paper proposes the support conditions and macro and micro measures to enhance China MF efficiency.There are28figures,26charts and215references in the paper.
