从生态联系的、有机的、系统的角度,用生态学理论法则解释供应链企业知识协同领域的问题。以生态学种群理论、生态位理论和食物链理论与供应链企业知识协同的契合研究为依据,模拟生物界种间关系及其进化方式建立供应链企业知识协同演化模型。该模型在兼容协同性竞争的基础上,依循寄生性知识协同、偏利性知识协同、互惠性知识协同和共生性知识协同的模式逐步演化。同时,从生态位的角度解释了供应链企业知识协同演化本质是生态位知识维的相互补充;从食物链角度解释了供应链企业知识协同演化本质是知识能量的逐级流动。 From the point of ecological connection, organic and system, this paper explains the problem of supply chain enterprise knowledge collaboration by using ecological theory. Based on the study of ecological population theory, niche theory and food chain theory and supply chain enterprise knowledge synergy, this paper simulates the interspecific relationship and its evolution in the biological world and establishes the knowledge co-evolution model of supply chain enterprises. The model evolves gradually according to the pattern of compatible synergetic competition and following the synergistic model of parasitic knowledge synergy, biased knowledge synergy, reciprocity knowledge symbion and symbiotic knowledge. At the same time, from the perspective of niche, it explains that the essence of knowledge co-evolution of supply chain enterprises is the supplement of niche knowledge dimension. From the perspective of food chain, the essence of knowledge co-evolution of supply chain enterprises is the gradual flow of knowledge energy.
