Study On The Historical Evolution And Changing Trend Of Animal Husbandry Regional Structure In Three Provinces Of Northeast China

The three provinces in northeast China are potential provinces for the development of animal husbandry.Since reform and opening up,the northeast three provinces with resources advantages,the drive of social economic development and policy support tilt,under the form of the three northeast provinces the opportunity of the development of animal husbandry in major,since the store policy reform in the corn,reducing production cost,the green animal products,such as the increase of the high-end consumer demand,the coastal areas,water network region ban limit,some domestic large-scale animal husbandry leading enterprises have northeast layout,livestock production moved westward,the northeast is accelerating the development of animal husbandry.Therefore,how to develop animal husbandry better and turn resource advantage into economic advantage has become an inevitable requirement for the development of animal husbandry in the three northeastern provinces in the future.The purpose of this study is to grasp the breeding and development of superior varieties in the three northeastern provinces as a whole,so as to better determine the reasonable regional layout of animal husbandry,make full use of resources,improve the efficiency of resource utilization,strive for greater economic benefits and social benefits,and accelerate the development of modern animal husbandry in the three northeastern provinces.This paper is divided into six parts: the first part of the research background and research significance of this paper,domestic and foreign literature review related to animal husbandry research,research content and research objectives,research methods and technical routes;The second part is related concepts and theoretical basis;The third part of the three provinces in the northeast of the main breed of livestock and poultry species structure to understand the current situation,especially the livestock and poultry out of the stock,yield,breed and breeding scale to illustrate the breeding industry in the northeast of the three provinces has a very large space for development;The fourth part through the analysis of the northeast three provinces animal husbandry region structure historical evolution and characteristics.By using the theory of comparative advantage and calculating the regional structure index,the paper analyzed the variety structure change of the three provinces in northeast China and got the dominant variety of each province;In the fifth part,cobb-douglas production function model is established by using data to empirically analyze the factors affecting the regional structure change of animal husbandry in the three provinces in northeast China;The sixth part is the development trend of breed structure of animal husbandry in the three provinces of northeast China and the policy Suggestions for the development of animal husbandry in the three provinces of northeast China.
