【摘要】：摘要：2012年我国水泥行业的产能利用率约72%,水泥行业存在着较为严重的产能过剩。政府不断出台相关政策推进水泥行业的兼并重组,优化行业布局,防止资源浪费,其次当前水泥行业利润水平下滑严重,水泥行业的兼并重组已经是大势所趋。我国在“十二五”规划中提出了具体的节能减排目标,水泥行业作为高能耗行业,其能源消耗强度的降低,对我国实现节能减排目标具有重要的作用。本文总结了国内外学者对企业规模和能源消耗强度的研究成果,对水泥行业的发展现状及能源消耗现状进行了详细阐述,当前水泥行业产业集中度较低,竞争格局分散,能源消耗总量大,能源效率与世界先进水平有较大差距。随后在理论上提出了能源消耗的规模经济性与能源消耗的规模不经济性两种假设及其解释。通过协整检验及构建误差修正模型,本文验证了水泥行业集中度与能源消耗水平之间存在着负向的长期均衡关系以及短期波动关系,水泥行业存在着能源消耗的规模经济性。格兰杰因果检验证明,行业集中度确实为能源强度的格兰杰原因,且行业集中度提高对能源强度降低的影响滞后期较短。最后,两者之间的非线性模型表明,我国行业集中度与能源强度之间存在着正U形关系。
[Abstract]:Abstract: in 2012, the productivity of the cement industry in China is about 72%, and the cement industry has a more serious overcapacity. The government has continuously introduced relevant policies, promoted the annexation and reorganization of cement industry, optimized the layout of the industry, and prevented the waste of resources. Secondly, the profit level of cement industry has been seriously declining. The annexation and reorganization of cement industry is the trend of the times. China's "12th Five-Year plan" put forward specific targets of energy saving and emission reduction. As a high-energy consumption industry, the energy consumption of cement industry is reduced, which plays an important role in achieving energy saving and emission reduction targets in China. This paper summarizes the research results of domestic and foreign scholars on the strength of the enterprise scale and energy consumption, and energy consumption situation of the development of the cement industry in detail, the current cement industry concentration is low, the competition pattern of dispersion, the total energy consumption, energy efficiency has a large gap with the world advanced level. Then two hypotheses and explanations for the scale economy of energy consumption and the scale of energy consumption are put forward in theory. Through co integration test and error correction model, it is verified that there is a negative long-term equilibrium relationship and short-term fluctuation relationship between cement industry concentration and energy consumption level, and cement industry has scale economy of energy consumption. Grainger causality test shows that the industry concentration is indeed the reason of the energy intensity of Grainger, and the impact of industry concentration increase on energy intensity reduction is relatively short. Finally, the nonlinear model between the two shows that there is a positive U relationship between the concentration of industry and the energy intensity in China.
