Economic Growth with Imperfect Protection of Intellectual Property Rights

This paper examines the growth effects of intellectual property right (IPR) protection in a quality-ladder model of endogenous growth. Stronger IPR protection, which reduces the imitation probability, increases the reward for innovation. However, stronger protection also gradually reduces the number of competitive sectors, in which innovation is easier than in monopolistic sectors. With free entry to R&D, the number of researchers in each remaining competitive sector increases, but the concentration of R&D activity raises the possibility of unnecessary duplication of innovation, thereby hindering growth. Consequently, imperfect rather than perfect protection maximizes growth. Welfare and scale effects are also examined.     

改制型民营企业的成长能力及其影响因素——与原生型民营企业的对比分析

通过对浙江省改制型民营企业和原生型民营企业的423份问卷调查，对比分析发现，目前的改制型民营企业正处于成长阶段，企业成长能力低于原生型民营企业，技术创新、民间融资、公共关系、业主角色和机构融资环境五层面的八个因素影响着改制型民营企业的成长能力，但影响改制型民营企业和原生型民营企业成长的因素存在差异。     

经济周期性波动与适度调节

改革以来,经济周期性波动的变化特征说明了我国经济的稳定性与抗风险能力增强;经济波动的根源是生产与消费的矛盾,矛盾激化到一定程度,经济运行就表现较大幅度的波动;市场条件与生产条件相背离是生产与消费矛盾激化的市场表现;生产条件短期是难以改变的,而市场条件的改变又是相对迅速的,宏观调控的重要作用就是要适时地调整并改变市场条件,使之与生产条件相适应;需要注意的是,这种调整应该适时适度,否则,反而会进一步加剧经济的较大幅度波动。     

Government financing in an endogenous growth model with financial market restrictions

Summary. In this paper, we develop an endogenous growth model with market regulations on explicitly modeled financial intermediaries to examine the effects of alternative government financing schemes on growth, inflation, and welfare. In the presence of binding regulation, there is always a unique equilibrium. We perform four alternative policy experiments; a change in the seigniorage tax rate, a change in the seigniorage tax base, a change in the income tax and a change in the fiscal-monetary policy mix. We find that in the presence of binding legal reserve requirements, a marginal increase in government spending need not result in a reduction in the rate of economic growth if it is financed with an increase in the seigniorage tax rate. Raising the seigniorage tax base by means of an increase in the reserve requirement retards growth and it has an ambiguous effect on inflation. An increase in income tax financed government spending also suppresses growth and raises inflation although not to the extent that the required seigniorage tax rate alternative would. Switching from seigniorage to income taxation as a source of government finance is growth reducing but deflationary. From a welfare perspective, the least distortionary way of financing an increase in the government spending requirements is by means of a marginal increase in the seigniorage tax rate. Under the specification of logarithmic preferences, the optimal tax structure is indeterminate. Received: March 20, 2000; revised version: June 26, 2001     

复杂性科学观下的高科技企业成长机制与成长指数设刮

复杂性科学打破了线性、均衡、简单还原的传统范式，开创了一种非线性、演化、复杂系统的新范式。高科技企业的成长由于具有非线性、动态性和自组织等复杂系统的基本特征，更适合于纳入到复杂性科学的新范式中研究。本文从高科技企业成长机制的复杂性特征入手，分析其成长机理，构建高科技企业适应性成长机制模型，并采用成长指数对高科技企业成长性进行评价，试图进行这方面的一些开创性研究。     

中国教育与经济增长关系的实证分析

通过对1978-2004年数据的分析,对中国教育与经济增长的关系进行了实证研究.结果表明,表征教育总量水平的财政教育支出对经济增长呈显著的正向作用,初等教育对经济增长的作用不显著,中等教育与高等教育对经济增长的作用十分显著.其中,中等教育的作用显著为正,而高等教育的作用显著为负.还考察了我国(1978-2004年)不同文化程度的人口对经济增长贡献的差异,并试图就职业教育对经济增长的贡献作初步探讨.     

嘉兴市产业结构与地区经济增长

该文通过实证研究，分析和度量嘉兴市不同产业对地区经济增长的作用，探讨各产业是以何种方式影响经济增长的，旨在为今后嘉兴市制定产业政策提供决策依据。     

对外贸易对西部经济增长作用的实证分析

西部大开发实施以来,西部对外贸易对GDP的拉动度并没有发生显著变化,对GDP的贡献也远低于全国平均水平。促进西部经济增长,应优化出口商品的结构,提高进口增长率,保持进出口平衡,拓展边境贸易,发展西部各省的特色经济。     

大型企业增长过快对我国消费和就业的不利影响

资本有机构成的提高,造成了劳动所得所占份额的相对减少,从而使得消费性需求相对不足,阻碍了经济稳定增长。我国大型企业的资本有机构成,无论从绝对数量还是从增长率上看都要高于中小企业,这种现象在工业企业中表现的尤为突出,而在建筑业和第三产业中则不是特别明显。所以我国有必要大力促进中小企业的发展,促进第三产业的发展,以防止我国出现最终产品的使用结构失调和就业不足的现象,从而保证经济稳定高速的增长。     

制度变迁对中国汽车工业增长贡献的实证分析

中国汽车工业增长是粗放型的，技术的贡献极低，而制度变迁贡献的潜力非常大。为此，一方面，要加快汽车工业的技术创新进程；另一方面，要深化汽车工业领域的市场化的制度变迁进程，以推动汽车工业走上高效、集约武增长之路。
