   近日我所吴方卫教授领导的课题组在2012年最新一期《Renewable Energy》(SCI)上发表论文,题目为“Willthe evelopment of bioenergy in China create a food security problem? Modeling with fuel ethanol as an example”。我所吴方卫教授为论文的第一作者,张锦华副研究员为参与作者。该文是吴方卫教授课主持的国家自然科学基金“我国生物燃料乙醇发展的社会经济影响和发展战略与政策研究”,及教育部、上海市自然科学基金、上海市社科规划项目等多项课题的阶段性成果之一。《Renewable Energy》杂志为可再生能源类顶级期刊,SCI收录,2010年的影响因子为2.566。

论文摘要如下:
This paper uses fuel ethanol from corn as an example to establish a theoretical model and framework to explore possible impacts of developing bioenergy on food security in China under short run and long run dynamic equilibriums with import supplements.From the three aspects including“fighting for food with people”,“fighting for land with food”,and international trade safety,the conditions that create food safety problems are discussed.In a closed economy,when the decrease in direct or indirect demand for corn caused by corn price rise is larger than the demand increase due to income increase,or when corn demand increase caused by fuel ethanol price rise is larger than the corn demand decrease caused by the decrease in government price subsidy for fuel ethanol,food security problem will appear.Food security problem can be solved by implementing trade policy when a stable import source is available.Otherwise the subsidies,substitutes,technology,etc.should be used to increase the rate of self-supply.Moreover,considering the status quo of corn market,the paper puts forward a set of policies of income and price subsidy,substitutes,and trade and technology to solve the problems.
