Evaluation each period of green food business enterprise piece, habitat monitor area, real object total amount and sale sum Be importation index sign; Again selection each year green food export sum is output index sign, to 1999-2006 year China green food development level of time sequence data calculation result enunciation: Green the food export's ability exaltation trend, which is a DEA for 2004-2006 years valid of age, but further analysis after detection: Green food yield 2002-2006 year average growth 29.2%, but export rate didn't°yet break 13%, and every year export rate growth not arrive a percentage point, and the demand of international market at continuously extension, particularly west nation green food consume growth the rate is in above 20%, this has already result in produce and foreign trade mutually separate, can't orientation open of market economy of request, this elucidation our country green food export development medium of strategy existence very great problem, For further expanding the international market, the analysis of market-orientation should be strengthened, the product quality and enterprise credit should be improved and the proper strategy and way to access market should be taken in order to break through the green barrier and keep up the competition ability which can be continuously developed.
评价将各期的绿色食品企业个数,产地监测面积,实物总量和销售额作为输入指标;再选取各年绿色食品出口额为输出指标,对1999——2006年中国绿色食品发展水平的时间序列数据计算结果表明:绿色食品出口能力呈现逐年提高趋势,2004——2006年是DEA有效的年份,但进一步分析之后发现:绿色食品产量2002—2006年平均增长29.2%,而出口率还没有突破13%,而且每年出口率增长不到1个百分点,且国际市场的需求量在不断扩大,尤其西方国家绿色食品消费增长率在20%以上,这已造成生产与对外贸易相分离,不能适应开放的市场经济的要求,这说明我国绿色食品出口发展中的战略存在很大问题,需要进一步开拓国际市场,加强市场定位分析,提高产品质量和企业信誉,并选择适宜的进入战略及方式,以利于冲破绿色壁垒和保持持续发展的竞争能力。
