项目摘要

The main aim of this research project is to develop dynamic general equilibrium models of closed and open economies and conduct theoretical analysis of long-run effects of intellectual property rights (IPR) and competition policy on technical progress and economic growth. More specifically, there are four objectives, and the extent to which each objective is achieved is briefly explained in what follows. The first objective is to demonstrate the existence of a non-monotonic relationship between IPR and the rate of technical progress. One of recent studies of Haruyama shows that such a non-monotonic relationship arises if heterogeneity of firms is introduced into a standard model of endogenous technical progress (this paper is still in progress). In other words, heterogeneity in firms' productivity can be considered as one of factors that give rise to a non-monotonic link between IPR and technical progress. The second objective is to show that perfect competition in the product market c … More an generate sufficient incentives for research and development (R&D). The result is established in Haruyanra (2007) who distinguishes between codified and tacit knowledge created in R&D. The paper focuses on the accumulation mechanism of those two types of knowledge. The third objective is to explore channels through which competition generates positive impacts on technical progress. The issue is considered in Haruyama (2006), who identifies three mechanisms through which competition promotes R&D. The fourth objective is to examine interactions between IPR and competition policy in promoting technical progress. In principle, it is possible that the problem is analyzed in the theoretical framework developed in the above-mentioned studies, but it is left for future research. It is worth mention that them are papers still in progress in addition to those published or made available in public. There are also papers which are not directly related to the specific objectives of the research project, but are born out of it. For example, there are papers on population and environmental issues. We believe that results of this research project are important in informing policy makers. On the other hand, there seems to be room for improvement in coordinating research among investigators.

本研究课题的主要目的是建立封闭经济和开放经济的动态一般均衡模型，对知识产权和竞争政策对技术进步和经济增长的长期影响进行理论分析。更具体地说，有四个目标，以下简要说明每个目标的实现程度。第一个目标是证明知识产权与技术进步率之间存在非单调关系。Haruyama最近的一项研究表明，如果将企业的异质性引入内生技术进步的标准模型，就会出现这种非单调关系（本文仍在进行中）。也就是说，企业生产率的异质性可以被认为是知识产权与技术进步之间产生非单调联系的因素之一。第二个目的是表明，完全竞争的产品市场， ...更多信息为研究和开发（R&D）提供足够的激励。Haruyanra（2007）对研究开发中创造的成文知识和隐性知识进行了区分，从而确立了这一结果。本文重点探讨了这两类知识的积累机制。第三个目标是探索竞争对技术进步产生积极影响的渠道。Haruyama（2006）对这一问题进行了探讨，他指出了竞争促进研发的三种机制。第四个目标是审查知识产权与竞争政策在促进技术进步方面的相互作用。原则上，可以在上述研究中开发的理论框架中分析该问题，但留待将来研究。值得一提的是，除了已发表或公开提供的论文外，这些论文仍在编写中。还有一些论文与研究项目的具体目标没有直接关系，而是由研究项目产生的，例如，有关于人口和环境问题的论文。我们认为，这一研究项目的结果对于向决策者提供信息很重要。另一方面，在协调调查人员之间的研究方面似乎还有改进的余地。少
