<p>　In perfectly competitive markets, an enterprise manager must adjust any input level to equate the marginal product value with price to maximize his profit. Nevertheless, this equilibrium may not always be realized in the real world. Elucidating the factors causing the disequilibrium is one of the important research fields of economics, namely the problem of allocative efficiency of input applications. <br>　The objective of this paper is to explicate the factors affecting the allocative efficiency of chemical fertilizers in rice production in China with the assumption that farmers aim to maximize their income. The reasons why chemical fertilizers have been chosen lie in the facts that the price data of chemical fertilizers are available and that chemical fertilizers are the most easily divisible inputs to realize their allocative efficiency. <br>　The main results are as follows. (1) The use of chemical fertilizers has been found to be allocative inefficient and the use level is less than the income maximizing level. (2) When the head of the household makes the decision about the use of chemical fertilizers and does this work himself, his education affects the allocative efficiency of chemical fertilizers positively, and the allocative efficiency of the households with the heads having been educated at least 4 years is significantly higher than that of the heads having been educated less than 3 years. (3) The farmer's age (experience) also has a significant effect, but there is a turning point at the age of about 37. Before the turning point, the allocative efficiency of chemical fertilizers rises as the head grows up. However, it begins to decrease as the head of household becomes older after the turning point. (4) The cadre occupation in the countryside affects the allocative efficiency of chemical fertilizers of the households with at least one member being cadre of the village statistically negatively.</p>
