基于偏离-份额分析法的河南省制造业竞争力研究

摘要

基于偏离-份额分析(SSM)方法,分别以全国和中部地区为参照区,对2009年以来河南省制造业行业竞争力进行实证分析.结果表明,(1)相对于全国和中部地区,河南省制造业整体经济增量均大于其区域份额分量,整体增速较快;(2)中高端制造业发展滞后,结构贡献率低;(3)相对于全国和中部地区,绝大多数制造业行业部门竞争偏量为正,制造业总体竞争效果指数大于1.%Based on the shift-share analysis method (SSM),the competitiveness of the manufacturing industry in Henan Province since 2009 was analyzed by using the national and central regions as the reference area respectively.The results show that:1) Compared with the whole country and the central region,the overall economic increment of the manufacturing industry in Henan Province is greater than that of its regional share,and the overall growth rate is faster;2) With the middle and high-end manufacturing industry lagging behind,the structural contribution rate is low;3) Compared with the whole country and the central region,the vast majority of the manufacturing sector competition bias is positive,and the overall competitiveness of the manufacturing index is greater than 1.
