本文通过构建一个中间产品种类扩张型的内生技术进步模型,探讨了开放经济条件下人力资本、国内研发与国外研发技术外溢影响经济增长的内在机理。对模型的竞争性市场均衡分析的基本结论是:技术吸收能力的提高、人力资本积累有利于长期经济增长,然而贸易开放度、技术水平差距对稳态增长率的影响效应具有不确定性。进一步的实证检验利用1996~2002年间我国30个省市的经济数据,考察了分别以人力资本、贸易开放度衡量的技术吸收能力对经济增长的影响,同时比较了进口贸易、外商直接投资这两类传递渠道的技术外溢效果,并就分析结果提出政策建议。

应用元胞自动机的建模理论和方法研究国际技术创新扩散的复杂性。基于技术创新扩散的微观机制,建立一个创新扩散的随机元胞自动机模型,对不同初始状态、演化规则进行仿真分析,结果表明企业的内部研发对于整个经济系统长期的技术扩散和创新起到关键的若没有企业的内部研发,长期的技术扩散不会发生,技术创新率的均衡值趋零。

New growth theory and empirical study have shown that in-house R&D has the dual role, which not only generates new information, but also enhances the firm's ability to assimilate and exploit technology spillovers. Based on two faces of R&D we put forward a cellular automata model to investigate the complexity of the innovation diffusion of economic system in the long run. The simulation results show that the roles of in-house R&D and network externality on the average rate of innovators in the economic system own the characteristics of S-shaped curve. Increasing the level of in-house research may shorten the take-off phase of the economy and improve the stability of the long run level of innovation rate.

【期刊论文】Environmental Pollution and Sustainable Economic Growth

Potential conflicts between economic growth and environmental degradation are central to the sustainable development debate. In a Schumpeterian model of endogenous growth with vertical innovations, we introduce non-renewable resources which cause flow pollution problems. It examines the conditions under which sustainable growth is both feasible and optimal. We also perform some comparative static exercises to analyze the effects of parameter variations arising from the economic environment on the steady-state growth rate.

This paper investigates the impacts that intermediaries may have on transaction efficiencies and market scales in electronic commerce. By comparing the utility levels of both buyers and sellers in two different market structures in our model, which refer to direct transactions between sellers and buyers, and transaction with intermediaries respectively, this paper point out the precondition under which intermediaries may exist. The impact of intermediaries on market scale is further explored by taking comparative static analysis on the influences of real transaction price change, and intermediaries' transaction efficiency on market scale. Finally, it is concluded that information asymmetry doesn' t necessarily lead to low market transaction efficiency and intermediaries are still needed in E-commerce if the benefits are larger than information costs.

【期刊论文】Technology spillovers, absorptive capacityand economic growth

By establishing an endogenous growth model with knowledge-driven R&D, this paper aims to investigate the relationship between international technology spillover, host country's absorptive capability and endogenous economic growth. The solution of the competitive equilibrium problem shows that long-run growth arises from the improvement of absorptive capability and higher human capital stock, while the relationships between openness, technology gap and steady-state growth rate are uncertain. Based on our sample data set of China's 30 provinces during the period of 1996-2002, econometric estimation of China's economic growth is also made. The estimation findings demonstrate that technology spillover is essentially dependent on host country's human capital investment and degree of openness, and FDI is a more significant spillover channel than import.

【期刊论文】基于贝叶斯正则化的TDBPNN模型在中国外贸预报中的应用及评估

基于相空间重构的非线性预报思想,建立一个时滞的BP 神经网络模型(TDBPNN),采用贝叶斯正则化方法提高BP 网络的泛化能力,并将该模型应用于中国进出口贸易的预测,结果证明改进的TDBPNN 模型具有较好的泛化能力,准确拟合了进出口贸易发展的历史值和趋势。区别于一般的预测评价,认为非线性预测不仅要注重数据拟合和精度改进,而且应该能够反映被预报系统的非线性特征。在分析模型预测精度的同时,通过计算拟合序列和原序列的非线性特征量进行模型评价,证实预测模型能够合理地“捕捉”到产生原序列的非线性系统的动力学特征。

This paper explores the link between environment and economic growth in a Schumpeterian model of endogenous growth with vertical innovations, in which we introduce non-renewable resources, which cause flow pollution problems. It examines the conditions under which sustainable growth is optimal. We also perform some comparative static exercises to analyze the effects of parameter variations arising from the economic environment on the steady-state growth rate.

【期刊论文】Environmental Pollution, Sustainable Growth and Optimal Economic Policies

Potential conflicts between economic growth and environmental degradation are central to the sustainable development debate. In a Schumpeterian model of endogenous growth with vertical innovations, we introduce non-renewable resources which cause flow pollution problems. First, we examine the conditions under which sustainable growth is both feasible and optimal; more specifically, we perform some comparative statics exercises to analyze the effects of parameter variations arising from the economic environment on the steady-state growth rate. Then, we study the equilibria in a decentralized economy compatible with our model, and we derive the precise levels of economic policy instruments that allow the implementation of the optimum.
