摘　　要：本文通过超越对数生产函数模型,对我国2004~2014年煤炭产业全要素生产率进行测度,并采用门槛效应模型估计了矿业权重叠对煤炭采掘业全要素生产率的非线性影响。通过实证研究,得出如下结论:样本期内,我国煤炭产业全要素生产率出现了先增后降的变动趋势,并且地区差异显著;矿业权重叠与煤炭产业全要素生产率增长之间存在非线性关系,煤炭资源税征收比重和煤炭产业集聚水平是影响这一非线性关系的重要门槛变量;煤炭产业的投资集聚与从业人数集聚,促进了煤炭产业的全要素生产率增长,但企业数集聚对煤炭产业全要素生产率增长形成了阻滞效应,煤炭产业存在不规模经济现象;能耗比重的下降(能源消费效率提升)并未带来煤炭产业全要素生产率的增长,我国面临着较大的能源生产方式变革的压力。This paper analyzes the nonlinear impact of mining rights overlapping on the total factor productivity of coal extractive industry based on the evaluation results of total factor productivity of coal mining in China,using the stochastic frontier production function model between 2004and2014.The main results show as follows:First,the total factor productivity of coal extractive industry of China shows a decline after increasing for several years and remarkable regional difference over the period of analysis.Second,there is nonlinear relationship between mining rights overlapping and total factor productivity of coal extractive industry.We employ two important variables to construct threshold model for testing the nonlinear impact between them,the level of coal tax levies and the coal industry agglomeration.Third,capital accumulation and employee assembling of coal industry promoted the total factor productivity,but enterprises concentration blocked the total factor productivity growth.It can be conclude that a diseconomy of scale could be found in the coal extractive industry.Fourth,the decline of energy consumption proportion would not result in the total factor productivity growth in coal extractive industry.China's energy industry faces great pressure to promote the energy production and consumption revolution.
