一国的专业化分工模式是由其要素禀赋决定的。一国的出口生产力水平(EXPY值)取决于企业家在生产效率高(即PRODY值高)的部门参与“成本发现”的数量,成本发现的过程使一国专业化分工模式变得不确定。一国的出口生产力水平不但由其专业化分工模式所决定,该国人均GDP水平对其也具有一定的影响。文章以101个国家2006年的进出口数据计算世界各出口行业的部门生产力水平(PRODY值),计算并分析各国2006年EXPY值的分布特点。同时,文章以2006年PRODY值为依据,以OECD 30个国家为分析对象,计算1999-2010年OECD国家EXPY值的变化趋势,并对其影响因子进行了相关计量分析。
A country's specialized division of labor is determined by its factor endowments. A country's level of export productivity (EXPY) depends on the number of firms participating in “high cost” (ie, high PRODY) involvement in “cost finding” and the cost discovery process makes a country's specialized division of labor less determine. The level of a country's export productivity is determined not only by its mode of specialization of labor, but also by its level of per capita GDP in the country. The article calculates the sector productivity (PRODY) of all the world's export industries based on the import and export data of 101 countries in 2006, and calculates and analyzes the distribution characteristics of EXPY values of various countries in 2006. Meanwhile, based on the 2006 PRODY value, the article takes 30 OECD countries as the analysis object and calculates the change tendency of the EXPY value in OECD countries from 1999 to 2010, and makes a related measurement analysis on the impact factors.
