湖北省进出口贸易能耗强度的测算与分析

Calculation and Analysis of Energy Consumption Intensity of Import and Export Trade in Hubei Province

将湖北省投入产出表中的42部门重新归类为6部门,建立能源经济投入产出模型。通过投入产出分析,测算2007、2012和2017年湖北省6部门直接能源强度和完全能源强度,计算得到湖北省总产出、出口和进口的平均能源强度,并定义湖北省对外贸易中的净省能强度。实证结果表明:湖北省出口具有相对全省产出平均水平更高的能源强度,出口产业倾向于能源密集型结构;同时,湖北省进口的能源强度高于出口和总产出的能源强度,净省能强度大于0,说明湖北省当前贸易条件利于能源节约。另一方面,持续下降的净省能强度值则显示湖北省贸易条件有恶化趋势,而进出口产业结构的调整有利于对外贸易的净省能强度的提高。

This paper uses the input-output table of 42 departments in Hubei Province to establish a 6-sector energy-economic input-output model.Through input-output analysis,the total energy intensity of 6 departments in Hubei Province was calculated in 2007,2012 and 2017.The average energy intensity of total output in Hubei Province,and the average energy intensity of exports and imports were calculated.The study shows that Hubei Province’s exports have a higher energy intensity than the province’s average output,and that the industrial structure of Hubei Province’s exports tends to be energy-intensive.On the other hand,the average energy intensity of imports is higher than the energy intensity of total output and exports,and the net energy intensity is positive.This proves that the current terms of trade in Hubei Province are conducive to energy conservation,but the continuously declining net energy intensity values indicate the terms of trade.There is a deteriorating trend.The adjustment of industrial structure will help increase the net energy-saving intensity of foreign trade.
