中国八大综合经济区经济发展差异测度与评价

研究目标:对中国八大综合经济区经济发展差异测度与评价。研究方法:针对多指标短面板数据,利用主成分分析技术构造两种新的聚类与评价方法。针对数据标准化后常见的地区差异测度不适用问题,提出一种新的测度指标。用偏相关系数和复相关系数探究经济指标间的真实关系。运用上述新方法对八大综合经济区进行实证分析。利用等级相关系数度量各地区在不同时刻排名的相关性及两种数据变换方法排名的一致性。研究发现:31个省份的经济发展水平排名比较稳定,省际差异显著存在,且呈现轻微的上升趋势,八大综合经济区之间差异也显著存在,但呈现下降趋势。东部沿海始终处于领先地位;南部沿海和长江中游稳中有进,其中长江中游进步最为明显;北部沿海协同发展初见成效,但内部差距仍然很大;相对而言,东北退步明显;黄河中游发展参差不齐;大西南和大西北发展依然滞后。研究创新:主要是方法上的创新,本文提出的两种新的聚类与评价方法,方法稳定有效,新的地区差异测度指标适用范围更广。研究价值:为类似问题的研究提供方法上的借鉴,并为相关部门制定区域协调发展政策提供依据。

Evaluation and Measurement of the Economic Development Differences among the Eight Comprehensive Economic Zones in China

Research Objectives:This paper evaluates and measures the differences of economic development among the eight comprehensive economic zones in China.Research Methods:Two new clustering and evaluation methods are constructed based on principal component analysis for short panel data with multiple indexes.A new measurement index is proposed to solve the problem that the measurement method of regional difference is not applicable after the data is standardized by Z-score method.And we use partial correlation coefficient and complex correlation coefficient to explore the real relationship between economic indicators.These new methods are used to analyze eight comprehensive economic zones.We use spearman rank correlation coefficient to measure the correlation of rankings of different regions at different times and the consistency of rankings by two data transformation methods.Research Findings:The economic development level of 31 regions is relatively stable,there are significant differences between provinces,and there is a slight upward trend,and there are also significant differences among the eight comprehensive economic regions,but there is a downward trend.The eastern coast has always been in the leading position;the southern coast and the middle reaches of the Yangtze River have made steady progress,among which the middle reaches of the Yangtze River has made the most obvious progress;the coordinated development of the northern coast has achieved initial results,but the internal gap is still large;relatively speaking,the northeast has retreated significantly;the development of the middle reaches of the middle reaches of the Yellow River is not synchronous;the development of the southwest and the northwest is still lagging behind.Research Innovations:This paper mainly focuses on the innovation of methods.The results of the two new clustering and evaluation methods are consistent,the methods are stable and effective,and the new indicator to measure regional differences is more widely used.Research Value:It can provide reference for the research of similar problems and provide basis for relevant departments to formulate regional coordinated development policies.
