基于Shift-Share的辽宁老工业基地区域经济弹性特征分析

研究老工业基地经济弹性特征对于增强其应对国内外扰动,促进落后的老工业基地全面振兴具有重要意义。本文采用区域经济弹性概念,在对1990—2015年辽宁老工业基地经济周期划分的基础上,测度各城市不同周期中经济抵抗力和恢复力表征区域经济弹性,借助shift-share分析法将区域经济弹性分解为产业结构分量和区域竞争力分量,揭示区域经济弹性的作用机制,结果发现：在不同时段内的区域经济弹性具有动态差异性特征,辽宁省对冲击扰动的抵抗力较低,容易遭受冲击影响;城市产业结构和区域竞争力均对区域经济弹性产生重要作用,且区域竞争力起主导作用,当前辽宁区域经济弹性受产业结构素质低和竞争力弱双重约束;服务业受老工业基地“路径依赖”影响,长期存在结构水平低和竞争力弱问题,第二产业结构素质和竞争力不匹配问题严重,路径依赖下的制度锁定现象仍旧存在,这都限制了辽宁的区域经济弹性水平。针对区域经济弹性特征和内部机制,提出了促进辽宁老工业基地经济振兴的对策建议。

Analysis of the regional economic resilience characteristics based on Shift-Share method in Liaoning old industrial base

It is of great significance to study the economic resilience characteristics of old industrial bases to promote the revitalization of these decayed old industrial areas and to enhance their capacity on resisting against domestic and global disruptions. This paper uses the concept of regional economic resilience to show the mechanisms underlying the economic development of Liaoning Province. First, it divides the economic growth rate of Liaoning Province from 1990-2015 into different economic cycles. Then, this paper characterizes the regional economic resilience of Liaoning Province by measuring its urban economic resistance and recovery feature in different periods. Meanwhile, the paper explores the mechanism underlying regional economic resilience by decomposing regional economic resilience into two aspects through the Shift-Share method: the industrial structure and the regional competitiveness. We obtained the following three main findings. First, regional economic resilience displays different characteristics which are dynamically changing across different periods. Compared with the whole nation, urban economy of Liaoning Province shows a lower resistance capacity against various disturbance, and it is more vulnerable to these disruptions. Second, both urban industrial structure and regional competitiveness can affect the capacity of regional economic resilience of Liaoning Province. We found that the regional competitiveness plays a more significant role, as the capacity of Liaoning’s regional economic resilience is constrained by its industrial structure and competitiveness. Third, “path dependence” has affected the development of service industry in the province for a long time, which is featured by the low level of industry structure and weak competitiveness. We also discovered that there exists a serious mismatch between the industrial structure level and the competitiveness in the secondary industry. Influenced by the phenomenon of institutional locking under the path dependence, the state-owned economy, which is often of poor management, accounts for a large proportion in the secondary industry. These all restrict the regional economic resilience of Liaoning Province. Aiming at exploring the characteristics and internal mechanism of regional economic resilience, the paper put forward some suggestions for the economic revitalization of Liaoning old industrial base.
