半农半牧区是连接农区与牧区的生态过渡区。其发展对我国生态环境改善、国民经济持续发展和民族团结等方面，均有重要的战略意义。事实证明，半农半牧区社会经济发展水平明显滞后于农区，而农牧业产业化发展方面，半农半牧区却有着农区和牧区所不具备的发展潜力。目前，半农半牧区既是影响国民经济整体发展水平和地区经济协调发展的地区，同时也是我国农村经济发展最具带动力、最具潜力的地区。在全国农村土地集体所有制实现形式多元化和农牧业产业化发展成为必然趋势的背景下，半农半牧区要选择什么样的经济发展模式是值得研究的课题。本书可能的创新性：第一，从研究视角上看，学术界有关半农半牧区相关研究成果非常多。但已有的研究大多是广义上的、宏观层面上的、自然科学领域的、技术层面上的研究。自然科学和社会科学相结合、宏观层面和微观层面相结合、技术分析和理论研究相结合的论著较少。本书在研究视角上试图超越这一局限。第二，从研究方法上看，已有的研究更多的是广义的半农半牧区研究，即农牧交错带研究。本书为了准确确定研究对象和研究范围，区分了狭义的半农半牧区和广义的半农半牧区，将原来的半农半牧区和农牧交错带的关系进行了梳理，对区域经济学的概念体系进行一定的拓宽。第三，本书基于研究的需要，将区域经济学中的城乡区域进一步细化为纯农区域、纯牧区域和半农半牧域。这对于半农半牧区这一特殊区域的经济社会发展具有重要的意义。

It has been 30 years since Reform and Opening up，the rapid development of Chinese national economy is unprecedented，and the annual GDP growth rate reached nearly 10%. In 2011，China’s GDP surpassed Japan，became the second ranking in the world. But the urban-rural dual structure and regional economic development imbalances still has not been resolved，therefore，the issue of agricultural and pastoral area stands out particularly.As the ecological transition zone，agricultural and pastoral area connects the rural area and pastoral area. The development of these areas has important strategic significant meaning to the improvement of China’s ecologic environment，suitable development of national economy and national unity. Facts have proved that comparing with the agricultural social development level，the development of pastoral areas and agricultural and pastoral areas is much slower. Simultaneously，agricultural and pastoral area has the potential developmental power on the agricultural industrialization developmental side，which both agricultural area and pastoral area could not hold. At present，agricultural and pastoral area does not only influence the overall development level of national economy and the coordinated development of regional economic zone，also the most driving force and the most potential region of the rural economic development in our country. Under the background of the diversified realization form of rural collective land ownership and agricultural industrialization development become inevitable trend，what kind of economic development form would be match with the agricultural and pastoral area become worth analyzing research.This paper consists of three parts：introduction，body part（including chapter one to chapter five） and conclusion.Introduction part consists of the background and significant meaning of selected topic，literature review，research contents，research methods and innovation and so on.Chapter one is about the formation of research area—agricultural and pastoral area. This chapter outlines the historical evolution of both formation and development of agricultural and pastoral area in Inner Mongolia through a lot of predecessors’ researches of historical documents and the final formation of the regional natural social features. Looking through the analysis of this chapter，the arrangement of government’s strategic policy plays a great deal in the formation and development of agricultural and pastoral area. The conclusion of this chapter provided a clue to the problem which laid in the last part of thesis that how the government functions in the process of these areas’ construction of economic development pattern.Chapter two relates to the recent development and the existing problem of agricultural and pastoral area. Starting from the important status of agricultural and pastoral areas，using a large number of official macro statistics and writer’s micro survey data，it analyzed the present situation of agricultural and pastoral area’s development，existing problems and the causes as well. Agricultural and pastoral area of Inner Mongolia has the function of preventing and protecting ecology，providing important mineral resources and electric energy to national economy，connecting the economic level between agricultural and pastoral area，in addition，and the potential function of national unity. However，looking from the current economic development situation and the existing problems in agricultural and pastoral area of Inner Mongolia，the very area has not played its important economic status and ecologic function. In the process of its development，there have existed such problems like slow-growth economy，the inharmonious social and economic development，the inharmonious ecologic and economic development. During the investigation，it turns out that related to its natural condition，the government’s system arrangement and historical and cultural tradition.Chapter three is about the development pattern and revelation of agricultural and pastoral area at home and abroad. Although there have not exact region and definition of agricultural and pastoral area abroad，the similar region does exist there. It analyzes and concludes the successful cases and experiences of economic development pattern in the similar geologic area both at home and abroad. Among them，the serious ecological deterioration and management experience lessons which caused by unreasonable exploitation and project in some foreign countries like the United States of America，the former Soviet Union brought warning role to land usage and exploitation in agricultural and pastoral area in Inner Mongolia. In the meanwhile，the modern agricultural and animal husbandry business pattern in some countries like USA and Japan provided important reference value to ecological economic development pattern in agricultural and pastoral area in Inner Mongolia. The agricultural and animal husbandry business pattern in domestic region like Liaoning and Sichuan also provided important reference of specific operation mechanism.Chapter four is about the analysis of traditional economic development pattern. The choice of economic development pattern would effected by the main elements like resource condition，level of productivity，the function of government and social culture influence. The agricultural and pastoral area in Inner Mongolia restricted by the above factors，under the frame of the household contract responsibility system，its traditional economic development pattern had some change on the agricultural and animal husbandry business pattern and productive organization pattern. But the shortage of traditional economic development pattern always influences its better development of economy and society，also its development of industrialization，large-scale and intensity. The features like low labor productivity and bad social and ecological benefit became a clue to build a new type of economic development pattern.Chapter five is about the construction of a new economic development pattern in agricultural and pastoral area. The construction of ecological animal husbandry’s economic development pattern in agricultural and pastoral area of Inner Mongolia is the necessary demanded decision of national ecological strategy and modern agricultural and animal husbandry development，and also defining the connotation and characteristic of a new economic development pattern in agricultural and pastoral area based on the specific geographical location advantage，rich natural resources and unique cultural advantage. The main building system of ecological animal husbandry pattern consists of ecological animal husbandry，ecological agriculture and ecological livestock products processing industry. It deeply and detaily analysed the specific operation mechanism of ecological economic development pattern and thought the“plant-feed-work”circular economy would be the proper pattern. At last，it puts forward the key function of different level governments in the process of the development and perfection of ecological economic development pattern. The government should organize and vigorously develop the leading enterprices in agricultural husbandary field，promote the reasonable usage of agricultural industralized operation，improve the quality of farming and pasture，intensify the policy support of ecological economic development，governments at all levels integrated strength and increase investment to infrustructures，strengthen the government supervision and service function.In conclusion，it put it straight that ecological economic development pattern is the necessary choice of agricultural and pastoral area of Inner Mongolia decided upon advantages of region，resource and historical culture. There are still some differences between the circular mechanism of ecological economic pattern in agricultural and pastoral area and rural area，which needs further research.The possible viewpoints of this thesis are illustrated in the following sentences. First，when it mentioned to research perspective，there have been much related researches among academic field. But they were mostly analyzed from a broad sense，the macro level，natural science and technical level. The combination of natural and social science，macro and micro level，technical analysis and theoretical research have not used in the former researches. This thesis tried to overcome this limitation on the research perspective. Second，on the research method，the existing researches mostly are about generalized analysis of agricultural and pastoral area，which is the crisscross of agriculture and husbandry. This thesis distinguished the similar areas in order to actually determine the scope and object of research. It straightened out the relationship and broadened the concept of regional economic system.Key words：ecological economic pattern of agricultural and pastoral areas；“plant-feed-work”circular economic development pattern；Characteristic industry development pattern
