技术创新与动态规模经济的理论分析

在一定的技术条件下企业存在合理规模和最佳规模.企业要扩大生产规模以获取更大的利润,必须对现有的技术进行革新.否则,企业只能以同样的规模进行外延性扩展.经过理论分析得出企业的最佳规模随着技术创新将不断扩大.对于某项技术创新,企业的理性投资条件应是技术创新带来的可变成本的降低量不低于用于该项技术创新的投资量.当然,企业为了长远利益,也可以不遵循这个理性投资条件.

Theoretical Analysis of Technical Innovation and Dynamic-Scale Economics

Enterprises have rational and optimal scales under given techniques.An enterprise must be innovated technically to expand its productive scale and obtain more profit.Otherwise,the enterprise expands only by the same scale.The optimal scale will be expanded after the enterprise innovates technically.For a technical innovation,the rational investment condition is that the decreasing amount of variable cost is not less than the amount of investment.Unless the firm considers the long term interests,it can also not abide by the condition.
