中国省级知识型服务贸易出口潜力及其影响因素分析

Knowledge-intensive Service Export Potential and its Determinants in China's Provincial Economies

本文通过构建随机前沿服务贸易出口模型,首次估计了投入类要素和约束类条件对中国省级知识型服务贸易出口的影响,并对近年来中国各省知识型服务贸易出口效率进行了测度。结果表明,我国知识型服务贸易出口效率偏低且省际差异巨大,北上广三地出口效率高达90%左右,沿海发达省份接近50%,而内陆省份普遍仅有10%左右,这也进一步说明中国各省知识型服务贸易出口潜力巨大。结果显示,人力资本、服务业外资流入、政府财政支出等因素对各省知识型服务贸易出口具有较强的促进作用。

In this paper, we employ a stochastic frontier service export mod- el and firstly investigate the impact of factor inputs and domestic constraints on the knowledge-intensive service export in China＇s provincial economies. Base on this estimate, service export efficiency is defined and calculated to analyze the discrepancy of different provinces in China. The results show that the knowledge- intensive service exports are highly concentrated in Beijing, Shanghai and Guang- dong. The service export efficiency rate in Beijing, Shanghai and Guangdong reaches about 90%, but the rate in costal developed province and inland provinc- es is 50% and 10%, There is a large potential for knowledge-intensive service ex- ports in most provinces. Human capital, service FDI inflows and government ex- penditure are found to positively affect service exports.
