摘　　要：以四川省改革开放40 a区域经济增长历程为例,将比例性偏离份额模型应用于区域经济增长偏离类型、偏离格局和偏离轨迹研究.比例性偏离份额模型根据结构竞争分量和区域分量正负值组合形式划分区域经济增长偏离类型,根据结构竞争分量、区域分量演化过程和趋势划分区域经济增长偏离轨迹.为排除区域经济规模差异对不同区域偏离程度比较的影响,提出区域偏离度(Sj)及计算模型描绘区域经济增长偏离格局.实证研究结果表明,改革开放40 a,四川省各市州有区域弱势结构优势型、区域强势结构劣势型、区域弱势结构劣势型3种区域经济增长偏离类型.各市州主要有滞后型、领先型、置换型和波动型4种区域经济增长偏离轨迹.基于Sj计算结果得到四川省1978-2018年经济增长偏离格局,验证发现Sj标准差和地区增速存在负相关关系.Taking the regional economic growth course of Sichuan Province during the 40 years of reform and opening-up as an example, this paper applied the proportional shift-share model to study the types,patterns and trajectories of regional economic growth deviation. The proportional shift-share model divided the types of regional economic growth deviation according to the positive and negative combination form of structural competition component and regional component, and divided the trajectories of regional economic growth deviation according to the evolution process and trend of structural competition component and regional component. The level of regional deviation(Sj) parameter and its calculation model was proposed for excluding the influence of regional economic scale difference on the comparison of all regionals. The empirical study results showed that the deviation of regional economic growth in Sichuan Province had 3 types: regional weak structural advantage, regional preponderant structural disadvantage and regional weak structural disadvantage, and the deviation trajectory of the regional economic growth in Sichuan Province mainly manifested four types: retardation, leading, replacement and fluctuation during the 40 years of reform and opening-up. Based on the calculation results of Sj, the deviation pattern of the economic growth in Sichuan Province from 1978 to 2018 was obtained, which further verified that there was a negative correlation between the standard deviation of Sjand regional growth rate in Sichuan Province.
