Abstract: In Chinese rural areas with high-level township industry, the adjustment of rural economic structure and the change of agricultural function affect agricultural location. Mainly because of the introregional compensation of price scissors between agricultural products and industsial goods, the increase of opportunity cost and marginal cost, and the change of orientating resources, three mechanisms of choice are formed about sector, production means and management system.The impact of development on agricultural location was shown in four aspects: 1) transitional physical geographic region gradually loses its special advantage; 2) location transfer process results in the replacing cost of production; 3) agricultural location deviates from the location of processing industry, which results in the panic purchasing of agricultural products as raw materials; 4) location duality graduauy decreases.To minimize the negative effects of those impacts, four macro location policies are suggested: 1) cost compensation for the renewal of agricultural production base; 2) benefit compensation for pure raw material production areas; 3) protection of high-quality agricultural location; 4) beforehand cinstruction of reserve agricultural production base.
