应用σ收敛与β收敛方法对兰州一西宁城镇密集区2000-2010年的经济发展状况进行收敛测算。从时间断面把握兰西城镇密集区经济收敛或发散趋势的同时,以人均GDP为指标,以县级行政区为研究单元,采用GIS空间分析技术,对近10年来兰西城镇密集区经济收敛或发散状况进行空间模拟,从时间和空间两个纬度分析兰西城镇密集区经济发展过程。结果表明:①兰西地区整体经济增长自2002后呈现出σ收敛趋势,但收敛速度较为缓慢。局部空间结构相对稳定,收敛较弱。②兰西城镇密集区县域经济发展存在微弱的绝对β收敛,且以每年2%的速度收敛。通过控制人口、城市化水平、人力资本、经济实力等内生变量,收敛性得到明显改善,条件β收敛在缩小兰西地区县域之间的经济发展差距上具有一定稳健性。⑧以劳均GDP为指标,从截面回归分析结果可判断,2000-2010年,兰西城镇密集区城市间经济同时存在新古典主义和新增长理论的收敛机制。
應用σ收斂與β收斂方法對蘭州一西寧城鎮密集區2000-2010年的經濟髮展狀況進行收斂測算。從時間斷麵把握蘭西城鎮密集區經濟收斂或髮散趨勢的同時,以人均GDP為指標,以縣級行政區為研究單元,採用GIS空間分析技術,對近10年來蘭西城鎮密集區經濟收斂或髮散狀況進行空間模擬,從時間和空間兩箇緯度分析蘭西城鎮密集區經濟髮展過程。結果錶明:①蘭西地區整體經濟增長自2002後呈現齣σ收斂趨勢,但收斂速度較為緩慢。跼部空間結構相對穩定,收斂較弱。②蘭西城鎮密集區縣域經濟髮展存在微弱的絕對β收斂,且以每年2%的速度收斂。通過控製人口、城市化水平、人力資本、經濟實力等內生變量,收斂性得到明顯改善,條件β收斂在縮小蘭西地區縣域之間的經濟髮展差距上具有一定穩健性。⑧以勞均GDP為指標,從截麵迴歸分析結果可判斷,2000-2010年,蘭西城鎮密集區城市間經濟同時存在新古典主義和新增長理論的收斂機製。

After the economic development convergence is computed by convergence and convergence method from 2000 to 2010 in Lanzhou-Xining city-and-town concentrated areas, it is simulated by using the spatial analysis of GIS while considering the trend of convergence or divergence from the time section. Economic convergence or di- vergence in the past 10 years is analyzed from spatio-temporal coupling perspective in Lanzhou-Xining city-and-town concentrated areas. Some conclusions can be drawn as follows:① A trend of convergence has been appeared in Lanzhou-Xining city-and-town concentrated areas since 2002, but the convergence speed is relatively slow. Local spatial structure is relatively stable, economic convergence is weak. ② Presence of absolute convergence is weak in Lanzhou-Xining city-and-town concentrated areas, and the convergence rate of 2% per year. Convergence is signif- icantly improved by controlling the population, level of urbanization, human capital, economic strength, and other endogenous variables, and the conditional convergence can effectively narrow the development gap between regional county of Lanzhou-Xining city-and-town concentrated areas. ③ Using GDP per labor force as an index, there are convergence mechanism of neo-classical and new growth theory judged from the cross-sectional regression analysis results from 2000 to 2010 in Lanzhou-Xining city-and-town concentrated areas.
