摘　　要：技术进步贡献率是衡量技术进步对产业增长贡献份额的综合指标。选取1991-2009年苹果产量、物质、劳动、土地等投入产出数据,运用C-D生产函数和索罗余值方程,对我国苹果种植环节的技术进步贡献率进行测算与分析。结果表明,1995-2009年间,我国苹果种植环节技术进步率对苹果产出增长的平均贡献率为97.75%,土地投入增长率的平均贡献率为17.18%,而物质和劳动投入增长对产出增长的贡献率为负值。技术进步已成为促进苹果种植产出增长的首要因素,我国苹果种植正在由以传统要素密集投入为特征的外延式发展模式向以技术进步为特征的内涵式发展模式转变。Technical progress contribution rate is a comprehensive index,which measures the contribution share of technical progress to industrial growth.This paper selects input and output data of China＇s apple production,material and labor from 1991 to 2009,using Cobb-Douglas production function and Solow Residual to measure and analyze technology progress contribution rate of China＇s apple cultivation.The average contribution of technical progress rate was 97.75%,while the land input contribution rate was 17.18%,and material and labor input contribution rates were below zero during 1995-2009.Technical progress had become the primary promoting factor of China＇s apple output growth.China＇s apple cultivation is now shifting from extension-mode,which concentrates on factor intensity,to intension-mode,which concentrates on technical improvement.
