The household contract responsibility system carried out in the 1980s promoted the development of agricultural industry，but failed to substantially change the management model of small-scale peasant economy. In the 1990s，a large proportion of rural surplus labor force was transferred to cities with the development of market economy，participating in the chain of the market economy with the commercialized labor as the essential factor and making the wage of migrant workers the main source of rural household income. While going out to work has baptized the peasants with the modern way of life in the city，the agricultural production of small farmers’management model cannot support the rural families’sustainable existence and reproduction，nor can it meet the needs of the modern lifestyle. Migrant work，which depends on market structure and globalized economy，has become the main support of rural economy. However，due to lack of self-generation，rural economy is rather vulnerable to the restriction by market economy.
