An econometric study of the technical efficiency of agriculture in the Soviet Union before its collapse has not been done so far. In this paper, an attempt is made to measure the technical efficiency of agriculture for 15 republic countries of the Soviet Union from 1960 to 1990. We calculated four measurements of technical efficiency, ROIN, PTE, SE and MIX, and determined whether they converged or not. The measured total technical efficiency ROIN showed that these values were all very low and continued to decrease until 1990, just before the collapse of the Soviet Union. We also checked the degree of convergence of these efficiencies, but found that most of them did not converge but instead diverged. The fall of the Soviet Union would be explained by many factors. Our study was able to show that the large scale agriculture conducted in Russia like kolkhoz and sovkhoz was very inefficient, and that the efficiency went from bad to worse over time. Therefore, they could not control the agriculture of other countries even if they had them adopt the same agricultural policy as that applied in the Soviet Union. In this paper, we showed that agricultural inefficiencies of 15 republic countries were one of the reasons why the Soviet Union collapsed, by using the above econometric measurements.
