City Regional Spatial Structure And Labor Productivity In Northeast China

The correspondence between spatial structure and economic benefit has been a hot topicin Geography. Nowadays, with the development of economic globalization and the rapidurbanization in China, how spatial structure affects agglomeration externalities supplies usnew research field.To solve this problem, this paper quantify city regional spatial structure through thedimensions of monocentricity- polycentricity and centralization-dispersion, adopting urbanplanning, urban geography and urban economics, and other subjects research methods,processing data and pictures through SPSS, ARCGIS, using the data of 34 prefecture-levelcities in Northeast China in 2000. At the same time, the scale of central cities are alsoconcerned. We use all indexes to analyze labor productivity under different spatial structure.The research reveals that: (1) more central city size shows higher labor productivity; (2)polycentricity does not show higher labor productivity; (3)centralization shows higher laborproductivity; (4)centralization has size dependence and scale dependence on laborproductivity.It researches city regional spatial structure from local scale in incomplete region.This has significance theoretical and practical significance in the field of urban systemplanning.There are three parts in this paper except the introduction and conclusion.The first part is literature review(Chapter Two). We over view the empirical literatureabout urbanization externalities, spatial structure and urban performance, the interactioneffects between urbanization externalities and spatial structure.The second part is quantifying city regional spatial structure in Northeast China(ChapterThree). Two dimensions are quantifyed. The monocentricity- polycentricity dimension thattells to what extent the urban population is concentrated in one, or spread over multiple urbanplaces in a city region; and the centralization-dispersion dimension, which tells to what extentthe cityregion population is concentrated at all.Association of dimensions is also regarded.The third part is modeling for estimation city regional spatial structure and laborproductivity in Northeast China (Chapter Four). We use a Cobb - Douglas productionfunction to derive an empirical model, process data and then obtain empirical results.
