Divisionalization and franchising incentives with integral competing units

Existing game-theoretic models of divisionalization and franchising treat each firm's number of competing units as a continuous variable. We account for the integer constraint on divisions, and show that the continuous case reasonably approximates the equilibria of the discrete game.     

产业特性、区域异质性与我国国内价值链分工

基于区域间投入产出表和上游度模型,构建国内价值链分工地位、嵌入位置和增值能力指数,系统刻画1997-2007年我国国内价值链分工形态,应用面板数据模型对国内价值链的产业和区域异质性进行实证研究。结果发现,我国总体尚未形成严格的东中西梯次分布的价值链空间格局,产业属性决定国内价值链嵌入位置和分工地位,产业国有比重越高越有助于价值链分工地位提升,产业资本劳动比提升嵌入位置却恶化分工地位,产业规模对分工地位没有显著影响;区域FDI导致价值链低端锁定和增值能力弱化,区域创新投入强化产业直接价值增值、市场化水平的提高显著提升价值链嵌入位置,但二者与价值链分工地位的关系均不显著。优化市场环境、降低制度成本、选择差异化的区域产业升级路径是构建国内价值链的关键。     

效率与平衡视角下京津冀城市群产业发展水平测度

基于效率和平衡视角,通过纳入结构差异和体量差距构建新的产业发展水平测度方法,以此对京津冀城市群产业发展效率与平衡水平进行评价。测度结果显示：京津冀城市群各城市效率水平差异较大,中心城市北京的效率水平过高导致产业过度聚集。在较长时间内,城市群产业发展平衡水平并无太大变化,但是城市群内城市的竞争压力逐渐向城市群西南方向转移。进一步讨论结果显示：新方法的测度结果是可信的;金融、公共服务等行业在城市群内的分布出现了一定程度的优化,但是制造、教育和文娱等行业却在不断恶化,总体来看,京津冀城市群产业结构有待进一步优化。     

The exchange paradigm of constitutional economics: implications for understanding the third sector

This paper reconsiders the exchange paradigm of constitutional economics from the perspective of the theory of the division of labor. According to this theory, human wants can be satisfied by two basic mechanisms—exchange and self-sufficiency. The exchange paradigm of constitutional economics emphasizes the former mechanism while neglecting the latter. Building on major economic theories of the third sector, it is argued that the latter mechanism is more helpful than the former in explaining the existence of third sector organizations. The paper concludes by discussing implications of this argument for the further development of constitutional economics.      

From Experience: Demystify Creativity, Enhance Innovation

Creativity need not be a chance occurrence. The authors of this article believe there is a technology that facilitates creativity. It is a technology that can be learned and applied and managed. They describe the specific steps that they followed in helping a group of R&D professionals learn, apply, and manage the creative processes in the lab. It is a story of practical steps that dealt with the everyday realities of managing in a large corporation.     

地面数字电视广播传输标准SMCC+系统的关键技术

描述了由电子科技大学提出的地面数字电视广播传输标准SMCC (Synchronized Multicarrier CDMA plus)系统。通过与现有的地面数字电视广播(Digital Television Terrestrial Broadcasting)标准在调制方式、同步、信道估计、相噪技术、峰平比、编码等方面的比较，证明了SMCC 系统具有比现有的标准更优越的性能。     

Bank holding company affiliation and contracyclical lending by mortgage bankers

Bank holding companies have made significant inroads into the mortgage banking industry, primarily by acquisition. Federal Reserve Board approval of acquisitions is contingent upon the expectation of net public benefits. This study analyzes one of the benefits that BHCs claim will arise from acquisition of mortgage bankers—the flow of funds into housing will become more cyclically stable. Test results on a 33-firm sample of independent and BHC-affiliated mortgage bankers for 1973–1975 provide little support for this claimed public benefit.

A quantitative model for the evaluation of technological alternatives

This paper presents a quantitative model that may be of use to the national development planners, investment funding authorities, and entrepreneurs, who are confronted with the problems of choosing the appropriate technology among many available alternatives. The model provides a systematic and analyst-independent methodology for the multicriterion technology selection process, which requires consideration of socioeconomic as well as technological factors. The procedure is mathematically straightforward and has the capability of integrating both objective and subjective aspects of the evaluation process, resulting in a unified technology measure as a guide for decision making. A case study is presented to illustrate the applicability and workability of the development model.
