An Empirical Analysis Of The Coupling Systems' Economic Effect Under The Conditions Of Herdsmen Settlement

In recent years, with the implementation of the herdsmen settlement policy, herdsmen from nomadic to agricultural and animal husbandry combination, their way of life and production have changed. Coupling system research will help us to grasp the inherent contradiction of agriculture and animal husbandry systems. Furthermore, there's important practical significance in answer to how the traditional animal husbandry changed, and what kind of role the farming like to play, as well as to seek the coordinated development road of farming and animal husbandry.In order to evaluate the coupling system's economic effect based on herdsmen settlement, this study analysis the characteristics of agricultural production systems since herdsmen settlement, application of the optimizing of agricultural systematic structure theory and set up the concept of coupling of farming and stockbreeding system. And, agricultural system general income maximize is used as objective function when the linear programming model of coupling system is build. Based on the model, analyze different situational coupling system, they are: crop production, ratio of farm manure to fertilizer and forage costs. The main findings are:(1) By 2010, the Donggou Village of forage's acreage will account for 75.09% of the total area, which can provide adequate forage reserves for the development of animal husbandry. The structure and content of Animal Husbandry Department become more rational, and the proportion of livestock become more coordination. The number of big livestock accounted for 28.95% of the total livestock. The Donggou Village's total income from agriculture and animal husbandry is 26.5766 million Yuan, 9196.06 Yuan per capita income.(2) Coupling system can let herdsmen avoid harvest paradox, that is, after crop yields'increasing led to increased supply, through Coupling system's mediation, to increase demand, so that they could get more revenue.(3) Coupling system allows "the price of adverse selection" partial exist in livestock scale decision making, that is, when forage costs rise, it will let herdsmen increase the scale of livestock whose forage costs take up a great proportion in forage ration.Therefore, coupling system is one of the best choices of the Donggou Village. Finally, this study proposed some measures and recommendations for coupling system development, they are: to optimize agriculture and animal husbandry's layout, the development of standardization of the scale of farming, to promote agriculture and animal husbandry's integration and accelerate the development of feed industry, and so on.
