摘　　要：随着供给侧改革的持续推进,影响煤炭企业产出的资本、劳动和技术等传统变量所带来的规模报酬呈现加速递减趋势。同时,煤炭企业受储煤量和开采技术及自然地址条件等限制,产出量呈现明显的生命周期特征。本文以煤炭企业为研究样本,在回顾传统Cobb-Douglas生产函数和我国煤炭企业生产函数研究成果的基础上,指出影响煤炭企业产出的主要因素包括资金(K)、劳动(L)、矿山储量(W)以及技术进步状况(At)和自然地址条件优劣程度(Et),最后分析了上述要素的相关关系并讨论了在煤炭企业生命周期内,各要素对产出的贡献情况。With the continuous advancement of supply-side reforms, the returns to scale brought about by traditional variables such as capital, labor, and technology that affect the output of coal companies are showing a decreasing trend. At the same time, coal enterprises are subject to restrictions such as coal storage, mining technology and natural address conditions, and their output has obvious life cycle characteristics. Based on the review of traditional Cobb-Douglas production function and the research results of China’s coal enterprise production function, this paper takes coal enterprises as a research sample, and points out that the main factors affecting the output of coal enterprises include capital(K), labor(L), and mine reserves(W) and the status of technological progress(At) and the degree of advantages and disadvantages of natural address(Et), Finally, it analyzes the correlation among the above elements and discusses the contribution of each element to output during the life cycle of the coal enterprise.
