Based on testing heterogeneity of China′s industrial energy intensity by using diagnosis theory of dynamic pan-el data, this paper reclassifies the industries without heterogeneity and makes empirical analysis of industrial energy in-tensity, and then we obtain the following conclusions.Firstly, 6 in 37 industries have significant heterogeneity of energy intensity, therefore the rest of the 31 industries can be theoretically analyzed and empirically tested by the same dynamic panel model.Thus, we will obtain the wrong conclusions if we analyze energy intensity by using all industrial data without classification.After eliminating the interference of the heterogeneity industry on theoretical mechanism analysis of China′s industrial energy intensity, the inertial of economic variable, industrial state of operation, technology level, industrial structure and industrial scale have significant influence on energy intensity.%本文采用动态面板数据诊断理论对中国工业行业能源强度异质性特征进行诊断, 在此基础上重新归类出无异质性差异的工业行业, 并对其行业能源强度影响机制进行实证检验, 结果发现: 在所采用的中国37个工业行业中, 有6个行业能源强度存在着显著的异质性差异, 其余的31个行业可以由共同一致的动态面板模型进行理论分析和实证检验, 由此可见, 如果不加区别地简单将中国所有工业行业组合在一起进行能源强度的理论机制分析将会产生错误的研究结论; 消除异质性工业行业对中国工业能源强度的理论机制分析的干扰后, 经济变量的动态惯性、行业经营情况、 科技研发水平、 行业结构以及行业规模对工业行业能源强度具有显著影响.
