the net import meaning in Chinese

净进口量

China endeavors to increase its grain production so that its self - sufficiency rate of grain under normal conditions will be above 95 percent and the net import rate five percent , or even less , of the total consumption quantity
中国将努力促进国内粮食增产，在正常情况下，粮食自给率不低于95 % ，净进口量不超过国内消费量的5 % 。
China transferred actually the pollution footprint overseas although there existed a trade surplus in industrial products in the years of 1999 ~ 2001 ; the net imports of chemical industry helped the transfer of most pollution footprint in china ; the inflow of pollution footprint came mainly from the net exports of the textile and machinery industries
结果表明，中国工业产品出口的污染密度要小于进口的污染密度； 1999 ~ 2001年中国虽然存在工业产品贸易顺差，实际上却向国外转移了污染足迹；化学工业的净进口帮助中国转移了最多的污染足迹，污染足迹的流入主要来自纺织业和机械工业的净出口。
