摘　　要：在技术创新驱动经济发展的过程中,技术进步不仅直接通过提升资本要素的生产率水平来提升经济增长速度,而且也间接提升了资本积累的速度,由此将进一步提升经济增长速度,导致技术进步对经济增长速度的弹性大于1,形成了技术创新驱动经济发展的加速效用。当发展中国家剩余劳动力的转移依赖于资本积累的速度时,技术进步的速度还可以通过提升资本积累速度和剩余劳动力的转移速度来进一步提升经济增长速度,因此,发展中国家技术创新驱动经济发展加速效应更加明显。也正因为这一机理,发展中国家可能因为技术创新的速度过低导致经济发展速度过低从而陷入中等收入陷阱。In the process of technological innovation driving the economic development,technological progress not only directly enhances the rate of economic growth by improving the productivity level of capital,but also indirectly increases the speed of capital accumulation,which will further enhance the rate of growth.This mechanism led to the elasticity of technological progress on the rate of growth greater than one,which means the technological innovation can drive the acceleration of economic development.When the speed of transfer of surplus labor in developing countries depends on the rate of capital accumulation,the pace of technological progress can also improve the growth rate by raising the speed of capital accumulation and labor transfer,which makes it more obvious of the accelerated effect of technological innovation in the developing countries.Considering this mechanism,however,it is also possible for the developing countries falling into middle income traps on account of low economic growth in the wake of the low pace of technological innovation.
