Abstract：This paper qualitatively studies the influences of quality-safety’s improvement on producer’s incomes by building the function of quality safety cost. It compares the differences in various influences of improving food’s quality-safety on the production behaviors under different conditions. This paper preliminarily thinks the improvement of quality- safety level can offer an economic feasibility for the producers: one is due to the long-run cost which will tend to decline and there will be a profit-rising margin; and another is that we are able to find the maximum profit point。
