Abstract: Based on the theory of Gray Relevant Degree,the agricultural fund,labor force,and technology progress in the flow direction of every agricultural classification were studied.The results show that the marginal benefit of fishery fund is superior;the best profession of marginal value of output for labor force is animal husbandry,and the technology progress of best require is agricultural technology progress.If the total output value of agriculture needs a steady improvement,the limited fund must flow to forestry,the surplus labor force must transfer to animal husbandry,and the attention must be paid to the agricultural technology progress.
