迫在眉睫的能源危机促使中国努力寻找替代方案,其中生物燃料乙醇受到最为广泛的关注,并得到迅速发展。然而,中国大多数生物燃料乙醇以玉米为原料,其迅速发展造成原材料玉米价格猛涨,以及饲料价格飚升引发猪肉价格上涨,加上国际粮价上扬的影响,对中国的粮食安全形成威胁。在能源安全与粮食安全的角力中,中央政府选择了以粮食安全为重,连续下发文件对玉米燃料乙醇紧急刹车,要求严格控制玉米燃料乙醇生产,转而开发非粮乙醇。 The imminent energy crisis has prompted China to work hard to find alternative solutions, of which biofuel ethanol has received the most widespread attention and has been rapidly developed. However, the vast majority of China’s bio-fuel ethanol uses corn as raw material. The rapid growth of its raw material corn price and the soaring feed price triggered the rise of pork price, coupled with the impact of the rising international food price, threatening China’s food security. In the midst of energy security and food security, the central government opted for food security as the most important priority. It issued continual documents on the emergency braking of corn fuel ethanol, demanding strict control of corn fuel ethanol production and the development of non-grain ethanol.
