本地市场效应、比较优势动态化与地方中枢型产业的选择

空间经济学理论表明,基于市场规模的产业本地市场效是新的比较优势的源泉。从产业本地市场效应角度考察我国区域间产业发展,利用《中国区域间投入产出表》测算中国不同区域和不同产业的本地市场效应大小,即“超常需求”的大小,发现伴随规模经济的“本地市场效应”可以较好地解释我国产业空间结构的现象。根据产业本地市场效应,即以市场需求为导向来培育主要产业是构建现代产业体系的途径之一,是未来我国产业升级的重要方向。     

中国CO_2排放与经济增长联动性实证分析

笔者在测算我国1953年～2007年间CO2排放量的基础上,通过对数据的经济计量检验,建立联立方程组模型,研究CO2排放量与人均GDP间双向因果关系,并分析各种因素对CO2排放量的影响。实证结果显示,我国CO2排放量与人均GDP间变动关系并不是简单EKC模型中的倒U型,有着更为复杂的相互作用关联。人均GDP提高导致CO2排放量上升的同时,能源利用效率的提高、能源消费结构的改善,以及资本设备更新速度的加快,都将减少CO2排放。     

Does different NPD project’s characteristics lead to the establishment of different NPD networks? A knowledge perspective

In today’s highly competitive and globalised marketplace, firms need more and more to develop new knowledge and capabilities to leave behind their competitors, thus gaining market share. Knowledge is fundamental for success because a firm that knows more, often develops more sustainable competitive advantage. Networks, like those oriented to New Product Development, seem to be valuable means of learning, as firms could not achieve alone the same results, or at least not as quickly. Through this integrative systematic review, we are interested in understanding whether different New Product Development projects correspond to different New Product Development networks in terms of knowledge exchanged among the partners involved. Our results highlight the presence of four types of New Product Development networks deriving from the combination of the degree of innovation characterising the project and its mode of development. Implications and future research are also proposed.     

Anti‐immigration policy in the destination country and skilled–unskilled wage inequality in a source economy with or without unemployment

This paper is aimed at theoretically examining the consequence of the anti‐immigration policy adopted in the destination country on the skilled–unskilled wage inequality in a source nation using a couple of two‐sector, specific‐factor general equilibrium models in both the presence and absence of unemployment. Emigration requires incurring some capital cost for professional skill formation on the part of every prospective emigrant that adds to the opportunity cost of emigration. The authority of the destination country determines the number of visas to be granted and hence directly controls the magnitude of skilled emigration from the source country. In the migration equilibrium, the expected skilled wage income abroad is equal to the opportunity cost of emigration. In both the presence and absence of unemployment of unskilled labor, the outcome of the policy on the wage inequality crucially hinges on both the magnitude of the fixed cost of emigration and the technological factors. In the specific‐factor Harris–Todaro model, the degree of imperfection in the unskilled labor market is an additional factor. Finally, some policy recommendations have been made for protecting the interest of the poor unskilled workforce.     

县域经济增长中结构红利的测度及决定 ——基于中国1 820个县面板数据的实证分析

产业结构升级是经济增长的源泉之一。本文基于中国1 820个县的面板数据,采用Translog生产函数估计要素弹性,进而测度县域经济增长中的结构红利,同时构建空间误差计量模型对结构红利的影响因素进行检验。研究结果表明2002-2010年间,结构红利占县域GDP总值的444%,对县域GDP增长的贡献达到了2435%。劳均资本、劳均土地等变量对结构红利有显著影响,本文还发现,在东部、中部、西部三个地区,财政支出占GDP的比重对结构红利都有显著的负向影响。     

Product Patent Reform and its Impact on Korea's Pharmaceutical Industry

Our analysis focuses on the effect of U.S. government pressure on Korea to adopt product patents for chemical and pharmaceutical products. American pressure began in November 1985 and ended with the Korean Legislature's passage of a new patent law in December 1986. We conduct an event study of the effect of the new patent law on the value of Korean pharmaceutical firms listed on the Korea Stock Exchange. Regression analysis shows that the new law induced excess returns of-74 percent over the 14-month analysis period. The results suggest that adoption of stronger patent laws reduced Korea's wealth.

A Study of Mathematic Model to the Development of Regional Industry Cluster

This paper analyzes the factors that influence the development of regional industry cluster, which are location factors, accumulatable factors, and external factors. Then regarding the similarity between the development of industry cluster and biology community, a modified logistic model is built, and a field study is made between the real instances and the model.     

On the welfare costs of misspecified monetary policy objectives

This paper quantifies the effects on welfare of misspecified monetary policy objectives in a stylized DSGE model. We show that using inappropriate objectives generates relatively large welfare costs. When expressed in terms of ‘consumption equivalent’ units, these costs correspond to permanent decreases in steady-state consumption of up to two percent. The latter are generated by both the inappropriate choice of weights and the omission of variables. In particular, it is costly to assume an interest-rate smoothing incentive for central bankers when it is not socially optimal to do so. Finally, a parameter uncertainty decomposition indicates that uncertainty about the properties of markup shocks gives rise to the largest welfare costs.
