Evaluate Multiple Effects Of Integration Of Coal Resource

’The Kyoto protocol" in 1997 and "the Copenhagen protocol" in 2009 all show the efforts to cut carbon emissions and curb greenhouse gas emissions all around the world. For coal resources exploitation in the process of industrialization, resource waste and environmental pollution caused by the lack of management are serious, the government advocates for developing low carbon economy to achieve the sustainable development. To our country’s coal industry, integration of coal resources is imperative. This paper introduces the multiple effects of the coal resource integration from all aspects including the economic effect, management risk and the time effect of coal resource integration about the new round of integration of coal resources in China from 2008.This paper conducted a systematic review of literatures about the policy of coal resource integration research as well as the effect of coal enterprise performance evaluation. In the coal resource integration of multiple effect on the empirical analysis, selecting 21 coal industry listed companies in China from September 2008 to December 2013, this paper analyzes the economic effects of coal resource integration, resource integration effect on the asset-liability ratio, integration of comprehensive risk management as well as the time effect of listed companies using Difference-In-Difference Model; DEA model is set up for an analysis of economic efficiency and safety efficiency about the new round of integration of coal resource in China. The completion of the resource integration of coal resource in Shanxi Province plays an important exemplary role, therefore this article conducts the integration of coal resource in Shanxi Province separately. There are a few conclusions:First, the integration of coal resource in the country including Shanxi Province has a significant positive role in promoting economic development; large scale or comprehensive profit ability of the coal company integrated economic effect is better than small size; low comprehensive profitability of the company, the integration of coal resources has improved the scale economy effect and the safety production of coal enterprises. Second, on the whole integration of coal resources significantly reduces the risk of the company’s business; but the large-scale, high profitability of enterprises in the process of the integration of asset-liability ratio is higher; on the one hand, the companies having a large scale, strong profitability are better in using external funding to help internal economy; on the other hand, in order to avoid excessively high asset-liability ratio of coal enterprise operation risk, we should pay attention to the rate of assets; due to its integration of leading, integrated management risk of Shanxi Province is higher than the national average level. Third, the integration of coal resource in the time effect, integration of coal resource in the short term economic effect is significantly positive, its long-term effect remains to be tested. According to the results of the analysis, this paper puts forward three advices: building a modern coal industry, transforming technology into productivity, introducing the social capital.The research about multiple effects of integration of coal resource enriches the existing research results about the integration of coal resource; In practice, it can help some constructive policies put forward to minimize the adverse impacts further, improving the multiple effects of integration of coal resource.
