【摘要】 通过对北京海淀区城乡结合部的实地调查,探讨了快速城市化背景下城乡结合部的发展特征及其形成机制。发现:海淀区城乡结合部居民构成复杂且就业、收入不稳定,社会保障水平偏低的弱势群体集中;外来人口规模庞大且具有乡镇集聚指向特点,其生产、生活方式与状态对城乡结合部发展影响深远;土地产权复杂交错,土地征用和土地流转存在诸多矛盾;农村经济的长期影响和居民消费能力等制约了城乡结合部的产业发展层次,新兴产业区的高新技术产业、现代化服务业难以与当地传统、低端产业对接,辐射带动能力非常有限;基础设施总体欠账严重,其建设主体多元化、交叉化,投资能力存在差异。独特的地域特点、复杂的历史背景,以及制度、规划与政策的缺失是影响城乡结合部发展的主要因素,未来发展应注重体制、规划与决策的创新。更多还原

【Abstract】 Based on plenty of field work and relevant theoretic analysis,this paper unveils and summarizes the developmental characteristics and the driving forces of the urban-rural fringe of Haidian District.The conclusion is the same with other urban-rural fringes in Beijing and in other large cities of China.Results show that the composition of residents in the urban-rural fringe of Haidian District is very complicated.Many people have no steady job and income,and their social welfare is also at a lower level.The size of floating population is almost equal to that of domicile population,and most of them live in the villages and towns of Haidian District.The manner of living and working of floating population has great effect on the development of urban-rural fringe.The proportion of green land in urban-rural fringe is much higher,and the compensation of taking up green land and the development right in green belt has not been resolved very well.The village-owned land is nearly half of the total area.The scarcity of reasonable criterion on land expropriation,development and management results in heavy conflicts.The traditional rural economy and low purchasing power of people impedes the improvement of industry of urban-rural fringe.There are many new industry parks in urban-rural fringe,but because of the great discrepancy between high-tech industry and traditional industry,they can not match very well.It is difficult for high-tech industry to bring into play it diffuse effect.There are more investors and managers of infrastructure than one in urban-rural fringe,and their capabilities are different.To be worse,the responsibilities of building infrastructure among different investors and managers are intersectant.All of these bring up a "dirty,disorder,bad and dangerous" urban-rural fringe.Special location,complicated background and weak system,planning and policy are main factors that influence the development of the urban-rural fringe.更多还原
