Since the reform and opening up,China's export trade has maintained a rapid growth;meanwhile,China's energy consumption has been increasing sharply. "High export and high energy consumption" has become the feature of China's trade and economic development.In this paper,based on the input-output analysis approach,the authors have conducted an empirical study on the export trade and energy consumption of 21 trade industrial sectors.The results show that,China is a big net exporter of embodied energy.Assuming that the export growth rate of embodied energy maintains to be about 23.6%,the average annual growth rate of the past 32 years,and based on the input-output data of 2005,by 2030 China's net export of embodied energy would be over eight times more than the aggregate energy production,which is obviously infeasible.As a country of very low per capita energy,China must change its export pattern,encourage or restrain the export of different industrial sectors according to their energy consumption intensity,and promote structural change of energy-efficient exported products,so as to achieve the sustainable development.Accordingly,the authors put forward some suggestions. 展开更多
