能源工业固定资产投资与能源产量互动效应的实证研究

Empirical Study of Energy Industry Investment in Fixed Assets and Energy Production Interactive Effect

近年来,我国能源生产总量与能源工业固定资产投资快速增加,基于2000—2009年中国的省际面板数据,运用VRS模型测度二者之间的互动关系。研究表明,我国的能源工业固定资产投资利用效率呈现出阶段性和区域性差别,我国能源的生产效率总体偏低且不同省份之间的能源生产效率差别较大,我国能源企业进一步扩大固定资产投资规模有利可图。因此,应该从技术进步与技术扩散、行业整合、政府对固定资产投资的宏观调控等方面改善固定资产投资与能源生产的互动关系。

In recent years, the total amount of energy production and energy industry investment in fixed assets are increasing rapidly in China. The paper analyzed the interaction between energy production and energy industry investment in fixed assets by using the statistical methods and efficiency measure based on the interprovincial panel data during 2000--2009 years in China. The results show that there is a stage difference in utilization efficiency of energy industry investment in fixed assets in our country. The fixed assets investment efficiency of northern provinces is higher than others;however, energy production efficiency in China is generally low. Due to the differences of energy production efficiency between different provinces, energy enterprises will get greater benefit if they expand the scale of investment in fixed assets. Therefore, the relation between energy production and energy industry investment in fixed assets should be improved by technical progress, technology diffusion, industrial consolidation and macroscopic readjustment and control.
