摘要
选取1982-2007年的样本数据,在服务贸易竞争力常用指标基础上通过主成分因子分析法构建了我国服务贸易竞争力的综合评价指标,并以此作为回归因变量,借鉴波特的国家竞争优势理论模型,实证研究了影响我国服务贸易竞争力的各种因素。研究结果表明,采用主成分因子分析法构建的竞争力综合评价指标比目前普遍采用服务出口额作为竞争力替代变量的研究方法具有更好的模型回归效果和经济解释意义,最后针对实证模型的回归结果提出了相关的政策建议。
This paper empirically studies China＇ s trade competitiveness m service sector wire a compound index which is structured by using factor analysis method. Learning from Porter＇ s national competitive advantage model, this paper also empirically checks the varied factors which may affect China＇ s trade competitiveness in service sector. Comparing the results of this paper with those by using popular models, it finds that our method has stronger power in explaining Chi- na＇ s trade competitiveness in service sector. Finally it proposes some policy suggestions according to the results from the model.
