In January 2006 the government enacted the Renewable Energy Law to promote renewable energy utilization and production. The government promotes biomass energy policy which is divided into four categories biofuel rural biomass biogas and bioelectricity. The national bioethanol program was started in 2001 and the government strongly promoted the bioethanol program to provide an alternative fuel for gasoline. It is assumed the government will promote the bioethanol program in the future because of the increasing gravity of the energy security problem and the air pollution problem. Corn is the main feedstock for bioethanol production in China. Chinese corn consumption for feed and starch use has increased since 1990 and the domestic corn price has also increased since December 2004. Chinese corn ending stocks decreased dramatically from 123 799 thousand tons in 1999 2000 to 36 602 thousand tons in 2006 07 Figure 1 . When the government started to expand the corn-based bioethanol program corn ending stocks were abundant and the government tried to manage the decrease in these stocks. In China the domestic corn wholesale price increased from 1 190 Yuan ton in February 2005 to 1 547 Yuan ton in September 20065 because the Chinese corn supply and demand situation was very tight. Corn consumption for bioethanol was competing with corn consumption for feed food and other industries. In this regard the NDRC started to regulate corn-based bioethanol expansion on December 21 2006. This regulation allowed the current bioethanol production level in Heilongjiang and Jilin but limited further expansion of corn-based bioethanol
