Abstract: From the research perspective of accelerating the common prosperity of farmers and rural areasin China, this paper uses the chain decision analysis method to discuss the tandem type decision mechanism for such choices as whether industrial and commercial capital should enter rural areas, what type and field of rural areas to enter, and how to enter. This study holds that the choice of whether industrial and commercial capital should enter the rural areas is to seek the optimal solution under the existing constraints. The main line of the series optimal solution is the win-win comprehensive income covering economic, political, social and other dimensions as well as the multiple subjects including industrial and commercial capital, villages and villagers. The above conclusions suggest that it is better to encourage and guide industrial and commercial capital to participate in the rural revitalization strategy during the process of common prosperity. The policy system design and policy arrangement should focus on the mechanism of investment choice of industrial and commercial capital based on win-win comprehensive income, and the differentiated policies should be implemented with targets, so as to achieve reasonable returns of industrial and commercial capital while promoting the common development of villages and villagers, thereby to help achieve Chinese-style common prosperity.

Key words: industrial and commercial capital, rural construction, driving mechanism, policyarrangements, win-win comprehensive income
