技术选择、技术扩散与经济收敛

Technique Choice,Technological Diffusion and Economic Convergence

Lin(1994,1996a,b,1999,2001)的技术选择假说认为一个国家的经济结构是由其要素禀赋结构内生决定的。一个发展中国家政府所采取的发展战略如背离了最优的技术选择将影响该国的经济增长速度及是否能够向发达国家的收入水平收敛。本文构建了一个增长函数,除技术选择外,还同时考虑地理位置、政府质量等因素在长期内对各国全要素生产率(TFP)的影响。我们用跨国数据对该模型进行估计,检验影响长期TFP差异的各种假说,结果支持Lin的技术选择假说、Sachsetal (1995,1999)的地理位置假说,但结果未支持政府质量假说。

Lin (1994,1996a,b,1999,2001)hypothesizes that the economic structure of a country is endogenously determined by its endowment structure.If a developing country's development strategy results in a deviation of the technique choice from the optimal choice,the country's growth rate will be adversely affected and the country will fail to converge to the developed country.The paper constructs a growth function.In addition to technique choice,the function also considers the effects of geological location and the quality of government.The paper uses cross-country,time series data to estimate the growth function.The results support Lin's technique choice hypothesis and Sachs et al.'s location hypothesis.However,the results fail to support the government quality hypothesis.
