摘要
本文重点分析了企业创新对社会福利的影响,得出的主要结论如下:(1)独立创新对产品价格和产量的影响是不确定的,但当创新使产品价格下降或者创新使产品价格上升且使反需求曲线的弹性变小时,独立创新能够增加社会福利;(2)联合创新能够降低每个企业的成本,增加企业的研发开支、产量和利润,因而联合创新有利于社会福利;(3)在考虑了创新的溢出效应后,存在一个外溢比率的帕累托最优区间,但我们必须在创新激励与社会福利之间做出权衡。
The article mainly analyzes how innovation affects the social welfare and makes some conclusions as follows: firstly, influences on the price and output of products of innovation by oneself are uncertain, but innovation can enhance social welfare when it reduces the product price or raises the price but diminishes the elasticity of inverse demand curve. Secondly, innovation by cooperation can decrease costs and increase R&D expenditure,outputs and profits to every member of the alli-ance , therefore it is good to the social welfare. Finally, there exists a Pareto optimum set of the externality rate if externality is considered in the model, but we must make a balance between the innovation incentives and social welfare.
