한국 농업의 총요소생산성 추계와 분석(1955~2012년)

Measurement of Total Factor Productivity in Korean Agriculture, 1955~2012

This study estimates Total Factor Productivity in Korean Agriculture for the period 1955~2012 and analyzes productivity changes by employing Tὅrnqvist index method. The empirical findings of the analysis are summarized as follow. During the past 57 years from 1955 to 2012, total agricultural output has increased by 2.6 percent per year. The annual average growth rate of total agricultural input over the period is 1.4 percent. Consequently total factor productivity (TFP) accounts for 46 percent of the growth of production. Total agricultural output and input have increased rapidly until the early 1990s, but both have declined since then. Over the whole period of this study, the pattern of productivity change is noticeable. The drivers of agricultural growth has moved from inputs to productivity. Thus, the 70 percent of agricultural output growth until the early 1990s accounted for an increase of agricultural input, and hereafter agricultural growth is explained entirely due to the productivity growth.
