以中国沿海地区三大区域的工业经济差异为研究对象,采用具有分解特性的泰尔指数衡量1998年--2010年中国沿海三大区域——环渤海经济区、长三角经济区和环南中国海经济区的工业经济差异程度的变动过程,并将北京、天津、上海三大直辖市工业经济发展对区域工业经济差异的影响进行对比分析。结果表明:沿海地区的工业经济区域差异呈缩小趋势,地带内差异是区域差异的主要来源;作为区域经济增长极.三大直辖市对区域工业经济差异具有显著影响。
The study of industrial economic differences in the three coastal regions-Bohai Economic Zone, Yangtze River Delta Economic Zone and South China Sea Economic Zone used the Theil index, with decomposition property, to measure the trends of 1998-2010 extent of industrial economy differences in China's coastal regions. Then a comparative analysis was made of the effect of industrial economic development of Beijing, Tianjin and Shanghai, the three municipalities, directly under the Central Government on the regional differences. The results showed that: the industrial economic regional differences in coastal areas had displayed a narrowing trend, internal differences were a major source of regional differences and as the regional economic growth pole, the three cities had significant impact on the regional differences in the industrial economy.
