A Mathematic Model of Farm Household Land Transfer in the Three Gorges Reservoir Area
三峡库区农户土地流转的理论解析

The objective of this study was to theoretically analyze the development of land transfer using mathematic models and provide a convenient channel for the effective connection of transferrers in flexibly utilizing land-use rights. We assumed the production management goal was that land transfer optimizes the allocation of resources, labor force and land economic value. A theoretical decision model was established based on these assumptions. The function trajectories of factors affecting land transfer were identified theoretically in the Three Gorges Reservoir Area. Agricultural production net income, as the fundamental basis of transferrer behavior in making land transfer decisions, was found to be influenced by the original contract land area, agricultural production costs, agricultural product price, agricultural production income security coefficient and family capital ownership. The amount of land transfer net benefit was controlled by annual rent of unit area and transfer time, belonging to the fundamental index of transferrers evaluating land transfer net benefits and the effective transformation followed Game Theory. The probability of rural laborers dealing with off-farm employment and the wages of choosing off-farm occupations influenced non-agricultural employment net earnings; this is also the basic force and the most important factor for farmers to lose land dependence and pull the land transfer. Taking into account weak agricultural production and non-agricultural employment instability, the reservoir area land transfer predicament is that both sides would like to use the land transfer and mobilize maximum resources.
