210003本文采用物质流分析方法,研究了1995—2002年中国经济系统的物质输入和输出等相关指标,发现经济系统的物质需求总量和物质输出总量巨大,自然环境的生态压力短期内无法得到缓解;人均物质需求量不高,物质生产力也很低;环境库兹涅茨曲线呈现出倒“U”型,最高点出现在人均收入700美元,然后进入下降通道;技术水平是影响物质需求总量变化的关键因素;出口能源中的煤炭存在巨大隐藏流是导致生态贸易赤字的主要原因。
210003 In this paper, we used the material flow analysis method to study the related indicators of material input and output of China’s economic system from 1995 to 2002. We found that the total physical demand and material output of the economic system are huge. The ecological pressure of the natural environment can not be obtained in a short period of time Ease; material demand per capita is not high, material productivity is also low; Environmental Kuznets curve showing inverted “U” type, the highest point in the per capita income of 700 US dollars, and then enter the descending channel; technical level is affecting the total material demand The key factor for the change of quantity is the huge hidden flow of coal in export energy, which is the main reason leading to ecological trade deficit.
