服务业全要素生产率与服务贸易出口——基于新新贸易理论的视角

Total Factor Productivity and Export in Service Industry ——Based on New-New Trade Theory

采用非参数数据包络分析方法计算了我国服务业分行业企业全要素生产率的增长情况,并对行业生产率与行业出口规模进行时间序列分析和面板估计。结果显示,我国服务业分行业数据的实证检验结果与新新贸易理论的结论基本一致,即服务业生产率与服务业出口贸易之间具有强正向相关关系;且两者之间存在长期稳定的均衡关系,服务业生产率是服务贸易出口的原因。上述结果与新新贸易理论的结论是吻合的,说明中国服务业细分行业数据也支持该理论。

This paper measures the growth rates of total factor productivity （TFP） in services, using sequential DEA - Malmquist productivity index method. And then it takes time series analysis and panel estimation to examine the relationship between sector productivity and export scale. The empirical results are consistent with the conclusion of new - new trade theory. There is a strong positive correlation and long - term stable equilibrium relationship be- tween TFP and export trade in service. And TFP productivity is the Granger cause of exports in service industry.
