摘要
引用动物捕食的最优方法的进化论观点研究了技术创新对企业集团能量效率的影响 ,提出了相应的对策 .首先 ,描述了一类企业集团的能量效率的基本模型 ,给出了一个关于技术与市场需求关系的假设 .接着 ,研究了技术创新对横向型企业集团能量效率的影响 ,在建立起模型之后 ,证明了提高核心企业的能量效率的充分性定理 ,为核心企业提供了对策方法 .然后 ,研究了核心企业是下游企业的纵向型企业集团 ,建立了模型 ,并获得了类似的结论 .最后 ,举例说明了核心企业应该怎样根据能量效率进行决策的思想 .总之 ,把一个企业集团的成长看成一群动物的进化 。
This paper studies effects of technological innovations on energy efficiency of industrial groups by introducing the evolutionary views on the optimal ways in which animals search for food originally,coming up with their resolutions. First of all,the paper describes the basic model of energy efficiency of a class of industrial groups,giving an assumption about relations between technology and market demand,also giving an assumption about energy efficiency of firm A and B. Secondly, the paper studies the effect of technological innovation on energy efficiency of the horizontal industrial groups and shows the theorem which gives the sufficient conditions improving energy efficiency of the core firm after the model has been set up,coming up with a resolution for the core firm,and then it studies the vertical industrial groups in which the core firm is a downstream firm and obtains a similar result after the model has been set up. Finally,it provides an example that illustrates its idea telling the core firm how to make a decision according to energy efficiency. In short,we take growth of an industrial group as evolution of an animal group and try to apply the evolutionary ideas to economic research.
