China has experienced significant changes in its economy since late 1980s. Due to its rapid growth and export-oriented growth strategy, the gap of welfare levels between urban and rural areas has exacerbated. To correct the problem, China has introduced a agricultural policy framework called, 'Strong Agriculture and Benefits to Agriculture(强農惠農)‘ in 2004-2005 to support the agricultural sector. To confirm the effect of the policy, this study aims to estimate the welfare changes of rice farmers in North-East regionof China, namely Jílín-shêng (吉林省) and Hēilóngjiāng-shêng(黑龍江省). Also, the political power of the rice farmers in the region was estimated using Political Preference Function(PPF). A generalized model to estimate the welfare changes and political power has been developed. The result suggests that more significant change in political power of rice farmers has occurred in Hēilóngjiāng-shêng than in Jílín-shêng, where Yánbiān(延邊) is the Korean Autonomous Prefecture. In Jílín-shêng, the political power of the rice farmers has improved from 0.47 to 0.56, whereas in Hēilóngjiāng-shêng, it has improved from 0.33 to 0.71. Hēilóngjiāng-shêng is a more remote region to North-East than Jílín-shêng from Peking, the capital of China. Therefore, it is plausible that Hēilóngjiāng-shêng is more underdeveloped than Jílín-shêng, which resulted in relatively less political power of the rice farmers in Hēilóngjiāng-shêng.
