Through survey on actual situation of 1568 households of rice growers in Heilongjiang, Hunan and Zhejiang provinces, this paper focused on influence of super rice development on increase of China＇s grain yield, influence on increase of rice growers＇ economic in- come, difference in production cost and profit between the North and the South, as well as profit percentage of super rice in production, processing, and sales. It obtained following results： rice price determines rice growers＇ income; expansion of super rice extension area plays a great role in increase of China＇s grain yield; by 2015 and 2020, keeping the yield of other crops not changed, merely the extension of super rice can increase grain for 5 million tons and 11 million tons separately; super rice significantly increases rice growers＇ economic income; for production cost of super rice, the South is higher than the North, and the profit ratio of cost is up to 35.54% on average; with respect of profit in production, processing, and sales, the ratio is 1：2：1.5; with the yield of other crops unchanged, every increase of 1% in area percentage of super rice to rice will additionally produce 1 million tons of grain for China, which is equivalent to saving the yield of 133 300 hm2 farmland and can additional feed 3.5 million people. In view of importance of super rice production, at the same time of strengthening research on super rice variety, it is required to accelerate expanding production area of super rice in suitable areas. Since the development of super rice can support China＇s ration demand of increasing population, China should make effort to realize ＂one yuan for one mu＂ financial subsidy for super rice of main grain production provinces and counties. Besides, China should establish special financial plan for extension of super rice.展开更多
