摘要 生鲜供应链整体生鲜度的提升对减少浪费、提高供应链整体盈利水平及社会福利有重要意义。本文基于消费者效用理论研究了两供应商和单一零售商组成的供应链系统,构建了单周期下生鲜农产品生鲜度激励模型,模型以供应商为领导者,采用Stackelberg博弈方法求解得到了均衡状态下供应商、零售商的最优定价策略及供应商新鲜度努力选择。研究结果表明,供应商和零售商利润与消费者价格敏感系数呈反向变化,与新鲜度敏感系数呈同向变化。在价格竞争市场,供应商保鲜努力程度和利润与价格替代率呈反向变化;在生鲜度竞争市场,供应商保鲜努力程度和利润与新鲜度替代率呈同向变化。基于研究结论,厂商及政府应当联手引导消费者的消费观念,尽可能减少由于信息不对称引致的道德风险,在市场价格替代率不变甚至降低的情形下,提高生鲜度替代率,使得消费者的意愿支付价格上升,提高自身讨价还价能力,获取更多利润。 With continuous improvement of consumers' living standards,consumers' demand for food safety has converted into the demand of both safety and high quality. Food fresh degree is widely arising consum- ers' concern. Changes in consumers' demand for fresh food makes a great many retailers and suppliers in- creasingly concerned about perishable goods and strengthen the management of fresh food supply chain. However, as a result of the attributes of perishable :food itself and the lagging development of cold chain logistics technology, its management result is far from expectation. According to the data of CECRC, the loss rate of fruits and vegetables reaches 30~ per year, which causes around billions yuan per year. Based on the statement above, the improvement of whole fresh degree on fresh supply chain is chosen as research topic. The fresh degree advancement is of great significance to reduce waste, as well as improve the overall profitability of the supply chain and social welfare. The supply chain system composed of two suppliers and one retailer is maninly studied based on the consumer utility theory. The fresh degree incentive model of fresh agricultural products under single cycle is constructed. In the model, supplier is the leader. With the Stackelberg game method, manufactures" optimal pricing and optimal freshness effort selection strategy un- der the equilibrium state are obtained. Results show that supplier, retailer profit and consumer price sensi- tivity coefficient are in reverse change. In the price competition market, the degree of preservation effort, profit and price substitution factor of the supplier show a reverse change. In the fresh degree competition market, the degree of preservation effort and profit, with the substitution rate of fresh degree change in the same direction. Based on research conclusions, manufacturers and the government should cooperate to guide the consumer's consumption concept jointly, reduce the moral hazard caused by information asymme- try as far as possible and avoid the phenomenon of Gresham.
