This paper presents an evolutionary model of industry development, and uses simulations to investigation the role of diversity and heterogeneity in firms’ behaviour, and hence industrial development. The simulations suggest that economic growth is increased with greater variety, in the sense of the evolutionary process approaching the equilibrium faster and also, in the long run, moving faster from one equilibrium to a new, more advanced, equilibrium. This occurs due to higher variety caused by a more tolerant environment, and due to the higher probability of emergence of radical innovations.

多样性和宽容在经济发展中的作用

本文提出了一种产业发展的进化模型，并通过模拟研究了多样性和异质性在企业行为以及产业发展中的作用。模拟表明，从进化过程更快地达到均衡的角度来看，经济增长随着多样性的增加而增长，从长远来看，从一种均衡向新的，更先进的均衡发展的速度也更快。发生这种情况的原因是，更宽容的环境导致更高的品种多样性，以及根本性创新出现的可能性更高。
