Estimation of the Contribution Rate of Technical Progress in Apple Cultivation in China
摘要
Abstract
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 17.18G,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.关键词
