Research On The Evolution Of Urban Planning Practice Under The Changes Of The Urban Organizational System In Early-modern China (1921-1949)

The paper focusing on 1921-1949.And the research object is urban planning achievements and urban planning practices made by the municipal government as the main administrative body.The research content is the basic concepts,common terms,core theories,and technical methods,planning content,expression of results,and the relationship between subject and object of urban planning practice and its compilation results.Based on the urban system and spatial transformation under the social transformation in early-modern China,and taking the development of urban structure and urban planning practice in early-modern China as the clue,this paper studies the historical process and evolution characteristics of urban planning practice in earlymodern China.The first three chapters are the introduction(Chapter one),the theoretical and analytical framework of the research(Chapter Two),and the overall situation and historical basis of city organizational system and planning practice(Chapter three).Following the first three chapters,the main content of this paper is historical elaboration,characteristic analysis and historical investigation.The first part is the historical elaboration,which divides the research time scope into three historical stages,in order to explain the historical process of Chinese early-modern planning practice from the origin,development to the initial formation in the perspective of city organizational system.The first period is 1921-1928.It reviews the basic characteristics of urban planning practice in the early period of the establishment of the urban system,which has not yet been independent from the municipal government.The second period is 1928-1936,during which the urban planning was mainly based on urban design.In this period of time,the National Government of the Republic of China promulgated the City Organization Law.It formally established the municipal government’s status as the principal body of the urban planning,and the urban planning practice began to be on the right track.The third stage is 1936-1949,during which the administrative urban planning with regional development as the goal was formed.It expounds the historical process of the rapid development of urban planning and the preliminary formation of its practical system after the promulgation of the Urban Planning Law and the revision of the Urban Organization Law,especially during the postwar restoration period.The second part is theoretical analysis.This part deeply analyzes the formation path and main characteristics of urban planning in early-modern China under the influence of the city organizational system.The third part is historical investigation,dialectically examining the two-way interactive relationship between the practice of urban planning and city organizational system in early-modern China.It is proved that the urban planning system has been initially formed and the development process is a historical process of gradual pragmatism.The innovation of the thesis includes 3 aspects:(1)Based on the historical documents and quantitative methods,the development process of urban planning practice between1921 and 1949 was elaborated,and the evolution of the three stages of urban planning,namely,municipal planning with the agenda of urban transformation,urban design with the leadership of urban development,and urban planning with the goal of regional development,was summarized.It also examines the evolutionary relationships between the three stages and the reasons for their evolution.(2)It systematically analyses the formation,development and evolution of the six dimensions of the results of urban planning practice from 1921 to 1949: basic concepts,planning terminology,planning content,technical methods,forms of expression and subject-object relations,and demonstrates the development process of planning practice from municipal planning of an engineering nature under a local autonomy programme to comprehensive urban planning under a legal framework.The transformation from construction planning to development planning is also the autonomous path of China’s modern urban planning practice.(3)Methods innovation: based on the traditional method of planning history research "historical document research method",combined with the research technology of quantitative history.Content analysis method is used to combine literature analysis with mathematical statistics.The text content of planning practice achievements can be identified,translated,word frequency statistics and analysis,so as to intuitively show the historical original appearance,evolution context and development trend of early-modern planning practice,and further analyze the information hidden under the data group.
