摘要
将北京市本地的禽蛋经营者和外地的禽蛋经营者作为两个群体,分析了禽蛋流通模式选择的演化问题。通过建立种群演化动态模型,发现在劳动力密集型与资金技术密集型流通模式的选择博弈中,存在唯一的演化稳定策略,即未来劳动密集型(散装禽蛋)流通模式将退出北京市场;在加工流通模式与包装流通模式的选择博弈中,存在3个演化稳定策略,而现实的演化路径则取决于演化的初始状况。最后指出环境、禽蛋物流技术以及禽蛋加工技术是影响禽蛋流通模式选择演化速度的关键。图1,表2,参10。
This paper analyses the evolutionary problem of eggs＇ circulation mode choice in Beijing on the base that the native and the out-of-town egg operators are assumed as two competitive groups. After establishing the dynamic evolutionary model of population, we find that there is unique ESS in the choice game between labor intensive and capital ＆ technology intensive mode, that is, the labor intensive （eggs in bulk） circulation mode will exit the Beijing eggs market in the future; and there are three ESS in the choice game between processing and package circulation mode. The practical evolutionary path lies on the initial situation. Finally we point out that the industry environment, egg logistics technology and egg processing technology are the key factors that will affect the speed of eggs＇ circulation mode choice evolution.
