专利可以保护发明人的利益,但也会导致垄断,因此,如何确定一个最优的专利保护制度一直是很多经济学家探讨的问题。不同的发明具有不同的价值,因此理论上需要不同的保护方案,但由于存在信息困难,在现实中很难实现。本文提出了一个依靠发明人和政府进行谈判来确定专利制度的设想,并指出,由于专利的价值是逐渐显现出来的,因此谈判也应该分阶段进行,这样得出来的结果可能更接近于理论上的理想状态。 Patents can protect the interests of the inventors, but also lead to monopoly. Therefore, how to determine an optimal patent protection system has always been a problem discussed by many economists. Different inventions have different values, so theoretically different protection schemes are needed, but due to the existence of information difficulties, it is difficult to realize in reality. This paper proposes a concept relying on the inventors and the government to negotiate to determine the patent system and points out that since the value of the patent is gradually emerging, the negotiation should be carried out in stages, so the result may be closer to the theoretical The ideal state.
