开放条件下中国工业能源强度的影响因素分析——基于31个行业面板数据的实证分析

An Analysis of Influential Factors in China's Industrial Sector Energy Intensity under Open Economy——An Empirical Analysis Based on Panel Data Models of the 31 Industries

本文运用中国工业31个行业1998年-2004年的面板数据，分析了能源价格、FDI的进入程度、进出口商品结构、工业内部的行业结构和R＆D投资强度对中国工业能源强度的影响。研究发现，能源价格的上涨对提高工业能源利用效率有显著的促进作用；降低FDI的进入程度与R＆D投资强度都有助于降低工业特别是高能源强度行业的能源强度；降低高能源强度行业的出口额在工业出口总额中的比重，有利于降低高能源强度行业的能源强度，进口商品结构变化对工业能源强度没有显著影响；降低高能源强度行业的工业增加值在整个工业增加值中的比重，有助于降低全工业行业和低能源强度行业的能源强度。

This paper empirically examines the effect of energy price, the proportion of FDI in industries sectors, import and export product composition, industrial structure and R＆D investment intensity to the industrial energy intensity, based on the panel data of China＇ s 31 industrial sectors during the period from 1998 to 2004. The results show that increases in energy price contribute to a significant decline in industrial sectors. With a rise in the proportion of FDI in industrial sectors, energy intensity in industrial sectors increases, in particular for high energy - consuming sectors. The enhancement of R＆D investment intensity leads to a rise in energy intensity, especially for high energy - consuming sectors. The decline in the proportion of the exports in high energy - consuming sectors will help to reduce energy intensity in high energy - consuming sectors. Chang in import product composition don＇ t significantly affect industrial energy intensity. And changes in industrial structure among industrial sectors have a significant effective influence on energy intensity in China＇ s 31 industrial sectors and low energy - consuming sectors.
