研发边际收益递减条件下的经济增长

The Economic Growth with the marginal decreasing returns of R&D

MPRA Paper from University Library of Munich, Germany

Abstract: 基于“新”新贸易理论、“新”新经济地理的研究，本文拟建立“新”新增长理论的分析框架。在总结大量经验事实的基础上，本文否定了当前新增长理论中“知识生产边际收益递增或不变”这一不合理的假定，我们认为在企业异质并独立研发的条件下，产业内的知识生产即使存在边际收益递减，经济仍然可以持续增长。这一模型可以解释六个方面的问题：（1)产业为何有兴衰；（2）经济为何有周期；（3）经济收敛为何不稳定、世界大同为什么有可能难以实现；（4）知识和教育为什么可能对经济增长的作用很小；（5）市场经济、威权政治、利益集团对经济增长的作用有何不同；（6）中国过去为何衰落、现在为何复兴、将来如何发展。
