基于断裂点理论的辽宁省城市经济辐射力研究

STUDY ON ECONOMIC RADIATION OF CITIES IN LIAONING PROVINCE BASED ON THE THEORY OF BREAKING POINT

依据核心—边缘理论和辐射理论,对辽宁省城市经济辐射力进行研究和分析。运用断裂点公式、场强公式,利用SPSS16.0计算出辽宁区域中心城市沈阳、大连对其他城市的吸引程度,同时也计算彼此相邻的城市之间的吸引力。研究结果显示:沈阳、大连城市规模最大,沈阳辐射范围远大于大连的辐射范围,辽宁西部缺少次一级的中心城市。

Based on the center-periphery theory and radiation theory, the thesis researches and analyzes economic radiation cities in Liaoning province. Attractive scope of regional center cities of Shenyang and Dalian was calculated by SPSS16.0. Moreover, attractive power was calculated among adjacent cities through Breaking-Point tbrmula and strength formula. The research results show that： Shenyang and Dalian are of the largest city size. Attractive scope of Shenyang is farther than Attractive scope of Dalian. Lastly, there is lacks of a secondary center city in the Western.
