农地制度变迁中的农户行为规则探析

on the ground of land institution evolution, meeting the expected costs minimization to the current demand of farmers become theier main principles of decision-making on land using behavior. This articles illustrates the following opinions: in the period of planned economy, in which all agricultural land was operated by state or collectives and farmers could't "withdrawal" or "work alone" for the extreme risk of punishment, so farmers have being tend to seek other economic rent (eg. be lazy) and abtain the minimized expect costs. In recent years, the farmers are active in spontaneous land exchange, while the largescale land exchange campaign launched by government encountered resistance because it was incompatible with farmers' demand and these activities directly challenge the social safeguarding function of farmland to them. This demonstrates that minimization of the expected cost with the current demand is the important behavior characteristics of farmer's agricultural decision-making. It suggested that it is very important for the current agricultural land reform to respect vast farmers' wishes and establish reasonable and stable compensation mechanism to ensure the harmony of farmland exchange as well as the improving land utilization.
