摘　　要：This paper classifies capital into structure capital and equipment capital and uses the endogenous economic growth model to illustrate the role of capital-embodied technological change in economic growth. In addition, it adopts the capital quality index to adjust equipment capital stocks in order to examine the contribution to economic growth of capital- embodied technological change after adjusting for current capital service efficiency. The results show that embodied technological change （ETC） in equipment capital has an average annual growth rate of 4.78 percent, accounting for 10.6 percent of economic growth and 14.8 percent of the total capital contribution. The contribution of technological change varies with development stage and the contribution of different types of technological change varies. Compared with the 1980s, the period starting from the 1990s has seen a steady fall in the contribution of capital-embodied technological change, and a V-shaped evolution in the contribution of neutral technological change （NTC）, with the fall being larger than the rise.本文将资本分为建筑资本和设备资本两类,利用内生经济增长模型阐释资本体现式技术进步对经济增长的作用,并利用资本质量指数调整设备资本存量,考察资本即期服务效率调整后的资本体现式技术进步对我国经济增长的贡献率,结果显示:设备资本投资中的体现式技术进步年均增长率为4.78%,对经济增长的贡献率为10.6%,占资本贡献的14.8%。技术进步贡献呈阶段性变化,且不同类型技术进步贡献出现分化。相对于20世纪80年代,90年代后资本体现式技术进步贡献呈下降趋势,而中性技术进步贡献呈现先降后升的变化特征,但降幅大、升幅小。
