【摘要】：近几年我国煤炭产业集中度不断提高,大型煤炭企业集团的企业规模不断扩大。在此过程中,我国大型煤炭企业规模扩张与国内煤炭需求趋缓之间的矛盾不断加剧,目前我国大型煤炭企业乃至整个煤炭行业已处于一个相当困难的时期。经济运行“新常态”下,调控大型煤炭企业规模,提高企业的规模效率,帮助煤炭企业脱困是势在必行的。本文旨在使大型煤炭企业认识到自身规模扩张中存在的问题,在此基础上寻找调控其企业规模的有效对策。调控措施主要基于本文对大型煤炭企业规模的经济及行政两种约束要素提出的。对于大型煤炭企业规模的经济约束要素以及行政约束要素的研究也是本文的重点内容。本文对于大型煤炭企业规模的研究主要从营业收入以及煤炭产量两个角度展开。在进行规模现状研究时,本文运用数据包络分析法(DEA)对其进行了评价,认为当前大型煤炭企业几乎全部处于规模无效状态。在对大型煤炭企业规模适度性研究的过程中,文章以固定资产净额为标准将企业现有规模进行分组,并继续运用DEA模型对其进行分析。通过各组综合效率平均值的比较,本文将现有规模分为三个阶段,并对每个阶段不同分组下,大型煤炭企业的规模适度性进行分析。继而本文对大型煤炭企业规模的经济约束要素以及行政约束要素进行研究。文章从宏观及微观两个角度分析了大型煤炭企业规模的经济约束因素,并针对每一约束要素与大型煤炭企业规模之间的约束关系提出假设,构造出相应的面板数据模型,模型的求解结果显示,交易费用、总资产投入、市场竞争力以及地区GDP水平对大型煤炭企业规模有正向约束作用,而劳动力投入对大型煤炭企业规模具有负向约束作用。本文将行政约束要素定义为政府对大型煤炭企业规模监管过程中对于两者决策产生约束的因素,通过政府与大型煤炭企业之间混合策略静态以及动态博弈模型的构建及分析,最终认为大型煤炭企业是否选择超限生产即扩张规模受到政府的监管成本、政府对大型煤炭企业超限惩罚以及政府监管过程中接受的企业贿赂等因素约束。文章最后在前文研究的基础上提出有效调控大型煤炭企业规模的建议。认为大型煤炭企业在规模决策时应该注重经济效益,建设有效规模,将原煤产出与煤炭需求挂钩,优化结构,规划战略布局,优化生产过程,控制生产成本,提高生产质量。同时,政府应正确认识煤炭行业及煤炭企业的重要地位,在煤炭行业困难时期给予各地方煤炭企业关怀与鼓舞,帮助大型煤炭企业持续健康发展。
[Abstract]:In recent years, the concentration degree of China's coal industry has been increasing, and the scale of large coal enterprise groups has been expanding. In the process, the contradiction between the scale expansion of large coal enterprises in China and the slowing down of domestic coal demand is becoming more and more serious. At present, China's large coal enterprises and even the whole coal industry have been in a very difficult period. Under the "new normal" of economic operation, the scale of large coal enterprises is regulated and the efficiency of enterprises is improved. It is imperative to help coal enterprises to extricate themselves from difficulties. The purpose of this paper is to make large coal enterprises realize the problems existing in their scale expansion. On the basis of this, we seek effective countermeasures to control the scale of coal enterprises. The control measures are mainly based on the economic and administrative constraints on the scale of large coal enterprises. The economic constraints on the scale of large coal enterprises. The research on the factors and administrative constraints is also the focus of this paper. The research on the scale of large coal enterprises is mainly carried out from the perspective of operating income and coal production. In this paper, data Envelopment Analysis (DEAA) is used to evaluate the large coal enterprises, and it is concluded that most of the large coal enterprises are in a state of invalid scale at present. In the process of studying the appropriateness of the scale of large coal enterprises, Based on the net fixed assets as the standard, the paper classifies the existing scale of enterprises, and continues to use DEA model to analyze it. Through the comparison of the average comprehensive efficiency of each group, this paper divides the existing scale into three stages. And in different groups for each stage, In this paper, the economic constraints and administrative constraints of the scale of large coal enterprises are studied. From the macro and micro perspectives, the paper analyzes the large coal enterprises. The economic constraints of industrial scale, According to the constraint relationship between each constraint factor and the scale of large coal enterprise, the corresponding panel data model is constructed. The result of the model shows that the transaction cost, total asset investment, Market competitiveness and regional GDP level have a positive constraint on the scale of large coal enterprises. However, labor input has a negative effect on the scale of large coal enterprises. In this paper, the administrative constraint elements are defined as the factors that constrain the decision of the two decisions in the process of government supervision on the scale of large coal enterprises. Through the construction and analysis of the static and dynamic game model between the government and the large coal enterprises, it is concluded that whether the large-scale coal enterprises choose the over-limited production, that is, expand the scale is subject to the government's regulatory costs. The government restricts the punishment of large coal enterprises and the bribery of enterprises in the process of government supervision. Finally, the paper puts forward some suggestions to control the scale of large coal enterprises on the basis of the previous research. Coal enterprises should pay attention to economic benefits when making decisions on scale. Build effective scale, link raw coal output with coal demand, optimize structure, plan strategic layout, optimize production process, control production cost and improve production quality. The government should correctly understand the important position of the coal industry and coal enterprises, give the local coal enterprises care and encouragement in the difficult period of the coal industry, and help the large coal enterprises to develop continuously and healthily.
