碳生产率变动与出口复杂度演进：1992-2009年

Changes of Carbon Productivity and the Evolution of Export Sophistication： 1992-2009

采用1992-2009年的跨国面板数据，在测算出各国出口复杂度的基础上，实证分析碳生产率等因素对出口复杂度演进的影响。研究发现，碳生产率作为一种新的比较优势决定因素，对提高各国出口复杂度至关重要；不论是高收入国家还是低收入国家，碳生产率的提高都能够显著促进出口复杂度的提升；各类资本禀赋与出口复杂度之间存在倒“U”形关系，并且这种关系在高收入国家和低收入国家中存在差异；自然资源禀赋不利于出口复杂度提升的“资源诅咒”现象更容易在低收入国家出现；经济开放度的扩大更有利于低收入国家出口复杂度的提升。

Adopting multinational panel data from 1992 to 2009, based on the computed export sophistication index with considering heterogeneity of export products and the empirical analysis of the effects of carbon productivity and other factors on the evolution of export sophistication, we find that. as a new determinant of comparative advantage, carbon productivity plays an extremely important role; whether high-income or low-income countries, carbon productivity improve- ment can significantly promote export sophistication; there exists a kind of inverted ＂U＂ shaped relationship between every capital factor and export sophistication varying from high-income to low-income countries; the ＂resource curse＂ phenomenon, that is to say, natural resource is not conducive to the improvement of export sophistication, is much more likely to occur in low-income countries.
