增加值视角下中国区域间现代服务业比较优势研究

The Comparative Advantage of China's Inter-Regional Modern Service Industryfrom the Perspective of Added Value

基于中国碳核算数据库(CEADs)2012年、2015年、2017年中国多区域投入产出表,从增加值贸易视角,运用改进后的显示性比较优势指数(NRCA)对中国30个省份现代服务业8个细分部门的出口竞争力进行测算,分析比较中国区域间东中西部和东北地区现代服务业竞争力现状。结果表明:①大多数省份现代服务业部门竞争力较弱;②四大区域的比较优势部门数量较少,劣势部门数量较多,且区域内部各省份之间和区域之间都分布不均,发展不平衡现象突出;③现代服务业比较优势指数在不同年份变动显著。在此基础上,提出有针对性重点发展NRCA较高的部门、加大现代服务业扶持力度、聚焦产业融合发展、推动产业转型升级、提高科技服务能力和产业发展韧性等对策建议。

Based on Chinese multi-regional input-output tables in 2012,2015,and 2017 from the Carbon Emission Accounts&Datasets(CEADs),this study uses the improved revealed comparative advantage index(NRCA)from the perspective of value-added trade to measure the export competitiveness of 8 sub-sectors of modern service industry in 30 provinces of China,and analyzes and compares the competitiveness of modern service industry in eastern part of central western and northeastern regions of China.The results show that:①the competitiveness of modern service sectors in most provinces is weak;②there are fewer comparative advantage sectors but more disadvantage sectors in the four major regions,and the distribution of these sectors is uneven within and between provinces and regions,highlighting the phenomenon of unbalanced development;③the NRCA of modern service industries varies significantly in different years.Based on these findings,targeted recommendations are proposed to focus on developing sectors with high NRCA,increase support for the modern service industry,focus on industry integration,promote industrial transformation and upgrading,improve technological service capabilities and promote industrial development resilience.
