组织支持感、组织承诺与员工建言行为：与上司关系的调节作用

回报动机和可能存在的风险是员工是否采取建言行为的重要影响因素。通过对708个员工样本数据的分析,结果显示：组织支持感与组织承诺和员工建言行为之间存在强烈正相关关系;组织承诺在组织支持感影响员工建言行为的关系中起到部分中介的作用;与上司关系交互调节了组织承诺影响员工建言行为的关系。     

On the Samuelson–Etula Master Function and the capital controversy

Abstract

The paper addresses the ambiguity that surrounds the conception of capital and its role in neoclassical price-and-distribution theory. The difficulties encountered in the various attempts to define the marginal product either of capital or of a capital good are recalled and the conclusion is drawn that neither concept appears theoretically sound. This historical reconstruction is combined with critical discussion of the recent attempt by Paul Samuelson to determine income distribution by means of the “Master Function”, a device previously developed and presented by Samuelson himself with Erkko Etula, and its “non-neoclassical” marginal products. Rather than the existence of a continuum of alternative technical possibilities, this construction assumes the simultaneous use of a discrete number of methods of production for the same commodity. Even though each technique employs the inputs in fixed proportions, the coexistence of various techniques permits the full employment of an arbitrarily given vector of input endowments. As is shown here, however, the coexistence of methods required for the differentiability of the Master Function can take place, if heterogenous capital goods are used in production, neither in the case with stationary relative prices nor in the non-stationary Arrow–Debreu framework.     

论城市准公共物品的合理提供

城市准公共物品在城市经济发展中起着十分重要的作用。我国城市准公共物品的供给方式已多样化,但仍存在总量供给不足和供给结构不合理等现象。本文以满足公共需要、注重效率和公平作为依据,提出几种改进措施,以促进城市准公共物品的合理提供。     

The “swing of the pendulum” from public to market support for science and technology: Is the U.S. leading the way?

The structure and financing of science and technology activities are undergoing a slow, but profound, change. This change can be briefly characterized as a shift from relying and supporting public science to a stronger emphasis on “market-based” incentives for science and technology. In this paper we analyze this shift in a historical perspective, discussing both the theoretical explanations and the empirical trends of the ongoing change. While we do not claim to provide a comprehensive and exhaustive identification of the causes of this shift, we argue that it is largely driven by the perception of a shift of the U.S. policy towards market-based, rather than publicly supported, incentives for science and technology. This, in turn—given the strong economic performance of the United States over the 1990s—has influenced policies in most OECD countries, especially in Europe.We conclude by analyzing the evolution of research in U.S. higher education and find two major trends: an increasing diversity in the number of institutions of different types other than universities and a steady and continuous public funding of the leading U.S. universities. This has allowed the construction of an infrastructure now used largely by the private sector, but it also noted that the United States has not compromised public support for core areas or in those fields in which there is a clear perception that market incentives are not sufficient for meeting the strategic targets of the U.S. policy. The implication is that there is a considerable policy diversity in the U.S. practice and that all aspects of this diversity should be considered when using the United States as a reference.     

贸易自由化是如何影响我国出口产品质量的？*--基于贸易政策不确定性下降的视角

传统理论认为贸易自由化会促进出口产品的质量升级,但我国加入W TO后的情况却并非如此。文章基于贸易政策不确定性的视角,利用我国加入W TO前后美国对我国产品进行关税调整这一自然实验,通过倍差法分析了贸易自由化对我国出口产品质量的影响。研究表明：（1）在贸易自由化的过程中,贸易政策不确定性的下降会拉低我国的出口产品质量,且这一结论在改变质量测度方法、控制成本效应以及使用不同的产品属性、贸易对象和样本的情况下依然稳健;（2）贸易政策不确定性主要是通过广延边际上的质量调整降低了我国出口产品的总体质量,即在贸易政策不确定性下降幅度越大的产品中,有越多的生产低质量产品的企业进入出口市场;（3）在集约边际上,存续企业并未针对贸易政策不确定性的下降做出及时的产品质量调整,从而无法改变我国的产品质量在短期内下降的趋势。文章为我国如何在推行贸易自由化的同时实现出口产品质量升级提供了启示。     

财政支农、农业现代化与山西农业发展

采用协整与误差修正模型对改革开放以来财政支农支出、农业现代化程度与山西农业发展的关系进行了实证分析。研究表明：山西农业发展水平、财政支农支出和农业现代化程度两两之间存在协整关系,误差修正模型显示短期因素对山西农业发展与农业现代化的长期均衡关系、农业现代化与财政支农的长期均衡关系具有很强的调节作用;格兰杰因果检验表明,财政支农在长期会对农业的现代化程度产生影响,而农业现代化则促进了山西农业发展水平的提高,农业的发展也会对财政支农支出产生影响,财政根据农业发展的实际情况进行补贴。     

金融支撑体系对我国物联网产业发展的作用——基于我国物联网上市企业的实证分析

界定了金融支撑体系的内涵及其构成,阐述了国内外物联网产业发展现状,从理论层面分析了财政税收、商业银行、创业投资和资本市场对中国物联网产业发展的影响,并提出相关研究假设。以2010—2012年中国46家物联网上市企业的数据为基础,建立面板数据混合回归模型,实证分析不同金融支持方式对物联网上市企业绩效的影响。研究发现:留存收益、财税、股权和创业投资4种金融支持方式与物联网上市企业的绩效显著正相关;商业银行信贷支持与物联网上市企业绩效正相关但不显著,说明信贷资金利用的有效性有待加强。最后提出完善金融支撑体系以促进中国物联网产业发展的对策建议。     

节能环保产业科技支撑体系研究--论山西省生态文明建设的保障措施

十八大报告和新党章将生态文明建设与经济建设、政治建设、文化建设、社会建设并列,还放在了突出地位、摆在中国特色社会主义事业总体布局的高度上,事关我党执政的可持续性.山西省做为一个能源与重化工省份,因经济偏重,造成了一些环境污染、生态欠账的问题,“十二五”期间,“高能耗、高排放”给经济增长带来的污染压力还将持续增加;为了保障山西省生态文明建设落到实处、解决过去经济发展中所造成了一些环境污染、生态欠账的问题,实现绿色发展、可持续发展,必须实施创新驱动发展战略.因此,山西省要建立生态文明建设中节能环保科技的支撑体系,全面提升山西省节能环保产业的发展水平和速度,建成美丽山西.     

公共项目交易中的治理模式研究

本文在对公共品供给模式分析的基础上探讨了公共项目契约的形成和交易治理模式.非经营性项目由传统的公共部门垄断经营供给模式转化为对其实行代建制,准经营性项目实行公私合作的供给模式,并针对不同的供给模式给出了两种不同的治理模式以解决公共项目契约组织中的代理人问题.
