摘　　要：提升煤炭产业生产率水平,化解产能过剩,是当前推进煤炭产业供给侧改革的重点,而矿业权重叠在引致煤炭产业要素错配、产能异质性和不完全竞争方面发挥了重要的影响作用,是影响煤炭产业生产率变动的重要因素,化解矿业权重叠风险,正成为推动煤炭生产和利用方式变革的重要突破口。本文利用2004—2014年中国煤炭产业分省市自治区的面板数据,实证检验了矿业权重叠对煤炭产业技术效率损失的动态影响。研究发现,矿业权重叠、生产能力不足和要素配置扭曲对煤炭产业技术效率损失具有显著性正向影响,考虑了内生性问题的面板工具变量法的估计结果仍支持这一结论。在分别引入煤炭资源税占地方财政收入比重和煤炭资源税占煤炭产成品收入比重作为门槛变量后,发现矿业权重叠对煤炭产业技术效率的门槛效应显著存在,其发展趋势表现出一种先扬后抑的曲线关系,当煤炭资源税征收比重跨越门槛值之后,矿业权重叠对煤炭产业技术效率的边际影响逐渐减弱。由于煤炭产业集中度水平和所有制结构的地区差异,集聚经济对矿业权重叠的"技术溢出"不足,并引致了煤炭产业技术效率的损失。显然,矿业权重叠风险的传导受到了政策因素、产能因素以及创新因素等因素的影响。因此,政策上需要全面推进税收政策、产业政策以及能源政策、科技政策等在内的统筹协调,减缓矿业权重叠对煤炭产业技术效率损失的风险传导。同时,政府还应加强对矿业权重叠区正常生产秩序的监管,减少不完全竞争对煤炭产业生产效率的影响。Increasing production efficiency and reducing surplus capacity is the key point to promote the supply side reform of energy industry in China.Meanwhile,the mineral rights overlapping is a typical factor which not only affect the production efficiency and imperfect competition of coal mining industry,but also lead to the factor mismatching and capacity heterogeneity.Mitigating mineral rights overlapping risk is becoming an important breakthrough to push forward the changes in the way energy is produced and used.We analyze the impact of mineral rights overlapping on the technical efficiency loss of coal mining industry,using the panel date of different province in China between 2004 and 2014.The main results show as follows:mineral rights overlapping,insufficient production capacity and factor allocation distortion have a significant positive effect on technical efficiency losses of coal mining industry.The results of panel IV models which considered the endogenous problem also support the conclusion.When adding the rate of coal resource tax on local fiscal income and the rate of coal resource tax on finished product income into the threshold model separately,as the threshold valuable,we find that mineral rights overlapping will have a signification threshold effect on the technical efficiency losses of coal mining industry,that is first go up and then down.When the proportion of coal resource tax levied exceeds the threshold,the marginal effect of mineral rights overlapping on the technical efficiency of coal industry gradually diminishes.Due to the regional differences in the level of coal industry concentration and ownership structure,the technology spillover caused by the agglomeration economies over the mineral rights overlapping has been insufficient and let to the loss of technical efficiency.Obviously,the transmission of mineral rights overlapping risk is influenced by the policy,capacity and innovation factors.Therefore,in order to alleviate the risk transmission,some measures should be considered to devel
