摘要 基于能源、资本和劳动三要素嵌套CES生产函数,分析了国际贸易引致技术进步偏向性的能源强度效应。国际贸易引致技术进步偏向于资本会影响能源要素相对份额,从而降低能源强度。结合我国36个工业行业1995—2017年的数据进行实证检验,并采用标准供给面系统方法测度了我国工业行业技术进步偏向性,识别了国际贸易通过技术进步偏向性影响能源强度的具体机制。结果发现,国际贸易引致技术进步偏向性通过能源要素相对份额显著降低了工业行业能源强度,但不同的贸易开放度、部门以及竞争程度的行业国际贸易引致技术进步偏向性对能源强度的影响存在差异。工业行业技术进步整体偏向于资本,国际贸易引致技术进步偏向于资本是能源要素相对份额下降的主要原因。研究为理解我国工业能源强度变化提供了新的视角,对降低我国工业能源强度的政策选择具有一定的参考意义。

Abstract: Based on the capital-energy-labor nested CES production function, this paper analyzes energy intensity effect of biased technical change induced by international trade. When trade causes the technological change biased towards capital, it could reduce energy intensity by decreasing the energy relative factor share. Combined with China’s 36 industrial sectors data from 1995 to 2017, it examines this effect. Using the normalized supply side system method, we also measure the direction of technical change, identify the mechanism of the energy intensity effect of biased technical change induced by trade. The results show that biased technical change caused by trade could reduce energy intensity significantly through the effect on energy relative factor share. However, for the sectors of different openness, industries and competitiveness, the energy intensity effect differs evidently. The technical change of whole industry is biased towards capital, which is the main reason why international trade reduces energy intensity. The research not only provides new sights for understanding the change of China’s industrial energy intensity, but also gives the policy reference of decreasing industrial energy intensity.
