With the start of rural reforms in Mainland China in1978,rural factor markets(i.e.markets for labor,capital,land,and technology)began to develop despite the facts that there are still collectively owned.Since1992,a market economic system has been introduced that has accelerated the development of the rural land market.With respect to land ownership,few land sales by collectives still take place.Market functions,however,gain importance in land requisition by the government.With respect to land use rights,the wasteland market already performs as a competitive market.In order to learn about the development condition of rural land market in developed areas of China as well as to analyze the influencing factors more scientifically,this paper makes a typical analysis of the operation of the land market at farm household level in Jiangsu Province based on the inquisition in the southern,middle and northern parts of Jiangsu Province.To test the effects of response of farm households' behavior to rural land transfer on agricultural land use changes in developed areas in China,the field work of questionnaires of240farm households' behavior had been held in6administrative villages respectively distributed in Suzhou City,Nanjing City and Yangzhou City of Jiangsu Province.Based on feedbacks of the questionnaires,a model was established to analyze agricultural land use changes influenced by farm households' during regional rural land transfer.It showed that,farm households with higher non-agriculture income proportion or with more constructed farmland promote farmland to be transferved out.Along with the gradual improvement of the rural land transfer system,the administration function of the government on farmland transfer has been gradually declined,and as far as the type of transformation is concerned,the types of rural land use change from the economic crop production to the aquatic farming.Given that,the article finally put forward some suggestions concerning sustainable agricultural land use.
