我国矿业税收的绿色化

矿业税收的绿色化是指矿业税收改革时应有利于环境保护和矿业的可持续发展。我国矿业税收中已有一些绿色化的规定,但也还存在一些问题。为促进资源节约利用和环境保护,实现我国矿业税收的绿色化,有必要将绿色化原则作为制定矿业税收的基本原则,对现行矿业所得税、矿产资源税、增值税等进行改革。     

Product innovation and firms’ ownership

This paper explores (i) the incentives for an incumbent firm to acquire an entrant willing to sell a product innovation rather than openly competing with this entrant, and (ii) in case of acquisition, the incentives to sell simultaneously both the existing products and the new one rather than specializing on a single variant. We prove that, in some circumstances, an incumbent firm can find it profitable to make an acquisition proposal to the entrant. Nevertheless, in this acquisition scenario, a product proliferation strategy is never observed at equilibrium. Furthermore, while being available for sale, sometimes the innovation simply remains unexploited.     

Outsourcing and structural change. Application to a set of OECD countries

The examination in this paper aims to bridge outsourcing and structural change analyses in order to obtain more accurate insights into the extent of outsourcing and to extract more reliable policy recommendations for dealing with its effects. We do this by applying a ‘battery’ of outsourcing measurements to a group of OECD countries from 1980 to the mid 1990s. Expected results (e.g. the idiosyncratic outsourcing patterns of the UK) are confirmed on a more systematic and comparable basis, while original results (e.g. the low integration of business services in manufacturing in the former socialist economies) are based on the exploitation of new data.     

Mixed Market Competition in a Quality Differentiated Duopoly Model An Approach to Banking Sector

This paper attempts to develop a theoretical framework to investigate the competitive implications of quality choices of financial institutions whereby they charge prices to consumers based on their willingness to pay for the service qualities in the mixed market scenario under vertical product differentiation model. Initially, it analyzes benchmark equilibrium solutions of monopoly and duopoly to establish the degree of quality differentiation between two private banks in an uncover market configuration. Further, it estimates the quality differentiation between private and public banks, and examines the interaction between two market structures keeping public bank as both leader and follower, and then measures the social welfare from different prospectives. The explicit operation of two stages Nash equilibrium game forecasted that public banks＇ monopoly seems to be still better than a private banking, and it is socially optimal. The outcome demonstrates a significant importance of vertical quality differentiation for policy implication in banking industry and provides an insight on the reasons of particular co-existence of public and private banking services in the specified location. In this context, it is concluded that the presence of public banks in banking industries is a crucial condition for obtaining the higher range of social welfare.     

基于交易费用理论的企业边界纵向一体化研究

交易费用理论认为，企业的最优边界在市场费用等于企业协调成本那一点，交易费用中的企业规模实质上是企业的纵向规模即纵向边界，企业纵向规模的扩张主要通过纵向一体化来实现。虽然纵向一体化能够有效地削弱人的机会主义和有限理性，克服不确定性，降低交易成本，但它并不必然是企业发展的一种好办法，企业发展到一定阶段，纵向分拆策略是有效的。企业的纵向边界呈现扩张与收缩交互进行的局面。     

国际垂直专业化、贸易分工模式与福利

在标准贸易理论框架下,通过引入垂直专业化和片段化生产,从理论上分析了国际垂直专业化对各参与国贸易分工模式的拓展及对国民和要素所有者福利的影响。研究结果表明,垂直专业化使一国比较优势由产品间深入到产品内部,进而使得各参与国贸易分工模式更为复杂,一国贸易模式可能会与该国原有的传统比较优势相悖;垂直专业化增进了世界福利,但在特定分工模式下可能会损害一国的福利,并且对于不同要素所有者福利的影响是不确定的。

水下高速气体射流的实验研究

本文对高速空气射流在受限约束下的动力学行为进行了实验研究。通过流动可视化揭示了高速空气射流在单筒和同心筒发射筒底部滞止、反转、而后向上绕经航行体或同心筒间隙向上喷入水中的演化过程。主要观察了单筒底部有无导流锥、同心筒三种间隙在不同压比和不同流量下的气水两相流态,并测量了航行体与发射筒的壁面压力分布。给出了航行体壁表面压力的动态变化规律,和沿轴向的分布规律。     

契约执行效率与垂直化结构

本文在LuigiPascali分析框架的基础上构建了一个两部门垄断竞争模型,考察不完全契约与垂直化结构的关系,并利用中国分地区分行业数据进行了检验。分析结果表明：契约执行效率的提高有利于垂直专业化分工;在契约要素密集度和物质资产专用性高的行业,契约执行效率与垂直一体化存在着明显的负向关系,在控制其他变量以及内生性问题后,这一结果仍然稳健;契约执行效率对人力资产专用性行业的治理结构影响不大。
