Abstract: As the benefit distribution is a common and critical problem in supply chain alliance, a fair and reasonable plan of benefit distribution is undoubtedly important for supply chain alliance. Based on the perspective of symmetrical and reciprocal symbiosis, according to the benefit distribution principle of production factors contribute, firstly, various production factors (e.g labor, land and capital) contribution rate are determined by Cobb-Douglas production function. Secondly, a game model about human capital factors (e.g labor) is set up and its optimal solution is given, yet the benefit about non-human capital factors (e.g land and capital) is distributed according to their investment proportions. At last, the optimal comprehensive allocations of the farmers, intermediary organizations and plantation companies are respectively obtained by numerical example in land transfer. The analysis in this paper has guiding significances not only for the distribution mechanism of the indirect rural land transfer, but also for the distribution mechanism of cooperation benefits between producers and suppliers.

Key words: rural land, indirect transfer, supply chain alliance, benefit distribution, symmetrical and reciprocal symbiosis
