出口活动、贸易强度与制造业行业生产率——来自我国中部地区的经验数据

Export Activity,Trade Intensity and Manufacturing Industry Productivity——Empirical Data from Central China

文章以我国中部6省制造业的21个行业为研究对象,采用DEA数据包络分析法科学测度了中部6省制造业行业最近十年的全要素生产率,再结合静态与动态面板模型对出口活动、强度与制造业企业生产率的关系进行了实证研究。结果表明中部地区的出口强度与整体制造业的生产率具有正相关,促进了中部地区发展;而出口活动对制造业生产率的促进作用主要是集中在高技术行业。对于传统行业,出口活动反而降低了制造业生产率。

This paper takes the 21 industries of the manufacturing industry in the central province of China as the research object, then uses the DEA data envelopment analysis method to measure the total factor productivity of the manufacturing industry in the central six provinces in recent ten years. Combined with the static and dynamic panel model, this paper enterprises an empirical study about the rela- tionship between the productivity of manufacturing and export intensity and export. The results show that the export intensity of the central region has promoted the productivity of the whole manufacturing industry and promoted the development of the central region. The promotion effect of the export activity on the manufacturing productivity is mainly concentrated in the high- tech industry. For traditional industries, export activity has reduced manufacturing productivity.
