Evaluation On The Eco-efficiency To Heilongjiang Areas

With great changes having taken palace in areas of Economic development, scientific and technological innovation as well as material and cultural life of the people, the problems of environment worse and destroying the ecological system that arise from those changes have become even heavily. So how to avoid the problem of harming the interest of environment caused by the economic development has been placed on the agenda. During the construction of ecological province, Heilongjiang province has not only paid more attention to economizing resource and protecting environment, but also implemented such measures as Pursuing Clean Production and developing the Recycling Economy to ease the contradiction between resources and environment. While what are the effects of those measures and how to evaluate the efficiencies between the resources inputted and environmental impact outcomes require scientific and reasonable quantitative evaluation. Being an efficient management and evaluating method, eco-efficiency can comprehensively and evaluate the performance of ecological construction reflect the actual conditions of outcome for Heilongjiang province. However, the methods and theories about eco-efficiency have not formed relatively mature and systemic; yet there is no common understanding between the academic and practical departments, especially for the assessing methods. So it is of great theoretical and practical implications for us to carry out deepen and systematic evaluating theories for eco-efficiency.Eco-efficiency for central and taking the example of Heilongjiang province, the article defines the connotation of eco-efficiency and some related concepts, gives the basic frame of evaluating eco-efficiency, designs the index system for eco-efficiency evaluating, analyses the theoretical model and carries out the empirical analyses to the13areas in Heilongjiang province. At last advices and count measures aiming at prompting the enhancement of Heilongjiang province are put forward.This paper defines the connotation of eco-efficiency and efficiency, analyzing the relation and difference of the concepts among eco-efficiency, dematerialization, and circular economy, the growth of economy, environmental load, energy efficiency and Pareto efficiency. The theoretical basis about the appraisal of eco-efficiency is discussed, including of the efficiency and fairness theory, resource economics theory, environmental economics theory, ecological economics theory, economics theory of sustainable development. Meanwhile, the basic frame of eco-efficiency evaluation is established from the aspects of subject, object, aim, index methods and standards of eco-efficiency evaluation, which sets the foundation for the evaluation and measurement of eco-efficiency.Method oriented of total factor and partial factor perspectives are proposed in the article. The ideas and process of evaluating the eco-efficiency based on DEA and MPI developed by Kuosmanen and Kortelainen are introduced under the perspective of total factor. While the method of PFE and PFEPI are then formed by the paper under the partial factor perspective. The combination of total factor and partial factor make the eco-efficiency evaluating more comprehensive and concretely.This paper constructs the evaluation index system of eco-efficiency for Heilongjiang Province. Based on deeply analyzing the status quo of economics, resources and environments of Heilongjiang province and integrating the concrete conditions of the province, the paper firstly describes the particularity of eco-efficiency index evaluated, and then discusses the following principles of establishing the index system, and at last constructs the evaluation index system of eco-efficiency for Heilongjiang Province from the perspectives of economics, resources and environments.Empirical analyses are carried out for13areas in Heilongjiang province under the perspective of total factor and partial factor. The results that under the total factor perspective shows that the overall efficiency of Heilongjiang province is not high and takes on an declining trend. Further more, according to the results of partial factor perspective analyses, the paper finds that the reasons that lead to inefficiency of Heilongjiang province ecological production is variant; but for most areas, it is the relatively low PFE of waste water, waste gas and solid waste that impede the enhancement of eco-efficiency of Heilongjiang province. As for the decreasing of13areas'MPI, it is mainly attributed to the declining of waste gas and solid waste's PFEPI.At last, pointing to the results of empirical analyses, the article proposes some improving countermeasures and methods from the levels of enterprises, industry mix, government and public participating, so as to push the construction of ecological province and building a resource thrift and environment friendly society.
