运用2000～2007年武汉城市圈各城市经济增长的宏观基本数据,分别从绝对差距、相对差距、收敛性等角度,对武汉城市圈9个城市间经济增长的差距进行了详细的分析。结果表明:无论是绝对差距,还是相对差距,在考察期间都是逐年扩大的;δ-收敛和绝对β-收敛的实证检验,都证明各城市间的经济增长趋于发散;在加入了反映该城市圈经济增长差异的经济结构变量和产权结构变量后,构建的3个模型检验都证明了其存在条件β-收敛。且农业产值比重和国有企业职工所占比重与各城市经济增长之间负相关,两项指标越大,城市经济增长的速度越慢;而工业产值比重则与各城市经济增长之间存在很强的正相关性,工业化进程越快的城市,其经济增长的速度越快。因此,加快产业结构调整和深化国有企业改革是缩小各城市经济增长差距的重要途径。
By using the macroeconomic data of economic growth of cities in Wuhan metropolitan region from 2000 to 2007, the differences in economic growth among 9 cities in Wuhan metropolitan area are analyzed in detail from the aspects of absolute difference, relative difference and convergence. The results show that both the absolute and the relative gaps are expanding year by year during the period of investigation; the empirical tests of δ-convergence and absolute β-convergence all prove that the economic growth among cities tends to diverge; After the economic structure variables and property structure variables of economic growth differences in the urban agglomeration, all the three model tests proved that β -convergence exists in their existence conditions. And the proportion of agricultural output value and the proportion of state-owned enterprise workers and the economic growth of each city is negatively correlated, the greater the two indicators, the slower the economic growth of the city; and the proportion of industrial output and the economic growth in each city there is a strong The faster the economy grows, the faster the process of industrialization is. Therefore, speeding up the adjustment of industrial structure and deepening the reform of state-owned enterprises are important ways to narrow the gap between the cities in their economic growth.
