Calculation and Analysis of the Contribution Rate of Agricultural Technological Progress in Guizhou Province

The contribution rate of technological progress is an indicator to measure the contribution of technological progress to agricultural production, which is important for analyzing the interrelationship between economic growth and scientific and technological progress, labor and capital. This paper uses the Solow residual method to measure and analyze the contribution rate of agricultural technological progress in Guizhou Province and makes suggestions for agricultural development. The research results show that the elasticity coefficient of capital for agriculture in Guizhou province during 2000-2019 is 0.52, the elasticity coefficient of labor is 0.38, and the elasticity coefficient of arable land area is 0.1. Capital inputs are currently the main driving force to promote agricultural production, and the contribution of labor and the arable land inputs to the growth of agricultural output is at a low level. The overall contribution rate of technological progress in agriculture is 40.35%, but it shows unstable changes from year to year. The capital contribution rate has an inverse alternating relationship with the contribution rate of technological progress.
