探究第三产业占比对人力资本积累的影响--基于我国2005年-2011年省级面板数据的实证检验

我国正处于产业结构转型的关键时期,一二产业逐渐向第三产业转移。以往研究大多落脚于人力资本对产业结构的影响,而忽略了由于产业转型带来的对高技术人才的需求推动了人力资本的积累。作者认为,产业结构的优化将有助于人力资本的积累,同时,文化消费、教育投入等因素也会影响到人力资本。本文使用2005-2011年,我国31个省份的面板数据,建立了多元线性回归模型,运用工具变量的方法,以金融发展状况作为第三产业占比的工具变量,进行实证研究。在控制了年份和省份的固定效应后,我们发现第三产业占比对人均人力资本有显著的正向影响,产业结构向第三产业转移有利于人力资本积累。在此基础上,我们提出了若干建议来推动产业结构的优化。

Pecking order as a dynamic leverage theory

Static tradeoff theories, which do not explicitly treat the impact of transaction costs, do not explain the policy of asymmetry between frequent small debt transactions and infrequent large equity transactions. Nor do these theories explain why the debt ratio is allowed to wander a considerable distance from its alleged static optimum, or how much of a distance should be tolerated. We offer a class of diffusion models that mimic this behaviour in a stochastic-dynamic framework and are designed to optimize a financing strategy using any static tradeoff theory as input. The models developed reveal the determinants of the size and frequency of equity transactions and the range of values over which leverage variations are tolerated in four generic scenarios. They also yield a new formulation of the cost of capital that recognizes stochastic transaction costs and a penalty for deviation from any static-optimal leverage. Our class of models augments the pecking order theory, provides a flexible quantitative framework for its implementation as a decision tool, and facilitates the formulation of additional hypotheses for its empirical validation. Symmetrically, our results show the importance of dynamic factors in designing and interpreting empirical tests of static tradeoff theories. The results presented have important implications for the role played by static tradeoff theories in a stochastic-dynamic framework. One such implication is that the static-optimal leverage has no direct effect on the firm's leverage policy in this setting. The target leverage for refinancing transactions is different from the static-optimal leverage, and the mean leverage is generally different from both. As a consequence, the latter cannot be used to estimate the former. Another implication is that even when the mean leverage equals the static optimum, mean reversion is not an optimal behaviour and therefore not a legitimate test for the existence of a static tradeoff in a dynamic context. Still another implication is that wide variations in leverage ratios cannot be interpreted as evidence of leverage indifference. It follows that the pecking order theory is consistent with static tradeoff theories and does not require the assumption of leverage indifference.     

影响我国电子商务产业结构的原因分析

从艾瑞咨询各年度的电子商务产业调研报告可以发现,自主型B2C电子零售产业的集中度要远低于平台型B2B和C2C电子商务产业,经过分析发现网络外部性、沉没成本、转换成本和价格或成本优势是导致集中度存在差异的主要因素,这些因素有可能对产业竞争带来长期伤害,本文试图寻找克服这些因素的方法。     

从资本结构到交易结构——探究企业金融微观结构

资本结构及融资行为是公司金融领域的重要论题,数十年来研究成果丰硕,但对商业实践真正有指导意义的成果却凤毛麟角。本文指出了到目前为止的资本结构研究的主要方向及其不足,提出了企业金融微观结构概念。本文认为,商学院的公司资本结构研究应该区别于经济学,深入到金融工具交易结构的微观层面,才能更深刻、真实地揭示金融实践原理,更好地指导金融实践。     

我国金字塔型控股结构下的大股东利益侵害行为研究

我国上市公司普遍存在"大股东"现象。大股东通过金字塔型的控股结构获得超额控制权,并"挖空"上市公司的资源,损害了广大中小股东的利益。本文在考虑我国上市公司金字塔型控股结构的基础上,构建大股东利益侵害行为模型,系统探讨了影响利益侵害行为的因素,并提出了制约大股东"隧道挖空"行为的对策。     

Some Reflections on the Spatial Dimensions of Occupational Segregation

This paper considers the role that urban spatial structure may play in the process of occupational segregation, and argues that neoclassical economic models of urban employment and residential location decisions have not considered the relationship between gender-based labor market status and space. The paper provides a critical feminist perspective on how conventional urban models have been used to explain patterns of segregation, and suggests reasons for limitations in existing theoretical and empirical analysis. It also explores ways in which economists can draw on work in other disciplines to develop fuller and more useful models of the relationship between urban spatial structure and occupational segregation.     

山东半岛蓝色经济区新兴产业融资渠道及选择研究

本文首先对新兴产业融资渠道现状进行阐述，然后选择山东半岛蓝色经济区新兴产业上市公司的融资期限和融资结构进行分析，最后对山东半岛蓝色经济区新兴产业上市公司和山东省非新兴产业上市公司进行比较研究，发现山东半岛蓝色经济区新兴产业融资成本较低，融资结构相对合理，但其与非新兴产业相比没有显著性差异。     

宋朝李诫编修《营造法式》对古代建筑标准化的贡献

中国古代封建政府中科技官职的设立，不但对古代科技的发展起到极大推动作用，也对古代标准化有重要的促进作用。宋朝李诫就是我国建筑史上受命于朝廷的官员“将作监”，是对建筑技术和标准的发展起到非常重要推动作用的人物。他编修的《营造法式》是我国建筑史上出现的一部重要技术法规，其内容是集建筑设计和施工技术手册、技术标准和规范、劳动定额为一体的专著。其中的材分模数制和斗棋结构是我国建筑史上非常重要的标准化成果。
