食品生产者的有机食品投资行为不仅关系到农业生产环境的改善,而且直接影响市场上有机食品的数量,进而影响市场中食品的总体质量安全水平。为此依据经济学理论,构建了食品生产者质量投资模型,并对有机食品投资行为进行了典型案例模拟。结果显示:影响食品生产者做出生产有机食品行为的因素依次为有机食品价格、生产力变动系数、生产者资本实力、质量投资、政府支持,有机食品相对于普通食品的高价可分解为技术变动效应与质量投资效应,而技术变动效应为主要因素。 Food producers’ organic food investment behavior not only relates to the improvement of agricultural production environment, but also directly affects the quantity of organic food in the market and further affects the overall quality and safety of food in the market. Based on the economic theory, this paper builds a quality investment model for food producers and conducts a typical case simulation of the investment behavior of organic food. The results showed that the factors influencing food producers’ behavior in producing organic food were organic food price, coefficient of productivity change, producer capital strength, quality investment and government support. The high price of organic food relative to common food could be decomposed into the effect of technological change And quality investment effect, while the technology change effect is the main factor.
