我国公共基础设施的规模效应及结构效应分析——基于1996-2010的制造业行业数据

基于三要素的成本函数,本文利用1996—2010年20个制造业行业的面板数据,考察了以能源、交通以及邮电通讯为代表的公共基础设施对产业部门的要素投入数量以及要素投入结构的影响。结果表明:公共基本设施投入不仅具有降低行业平均成本的作用,而且对行业成本结构具有显著影响。相对于劳动投入,要素投入更加向资本和中间品倾斜。     

Sense and sustainability revisited: the limits of total factor productivity measures of sustainable agricultural systems

Many economists have advocated and applied total social factor productivity (TSFP) (i.e., total factor productivity estimated with both market and non‐market inputs and externalities, and with all factors valued at social prices) as a single all‐embracing measure of agricultural sustainability. This paper reviews the conceptual and practical issues in measuring TSFP and shows that no one measure alone will be theoretically or empirically robust as an indicator of sustainability. TSFP is a conceptually flawed measure since inclusion of non‐market inputs and outputs and social price‐based valuation, in most cases, violates the theoretical basis underlying those estimates. Trends in TSFP also have limited value in diagnosing the nature of sustainability problems, unless changes in productivity are related to underlying changes in technology, human and physical infrastructure, and indicators of resource quality. More attention needs to be given to defining key indicators of agro‐ecosystem health and relating these measures to trends in productivity. This analysis must be sufficiently disaggregated and for a long enough time period to allow for spatial and temporal variability inherent in agricultural production. Secondary data at the district level on both conventional inputs and outputs and resource quality have recently allowed more quantitative estimates of sustainability and its causes. With limited data, yield growth decomposition analysis can often be used to provide valuable insights into sustainability problems. Meanwhile, there is a need to invest in long‐term experimental and panel surveys of farmers and their fields for key production systems in order to provide long‐term data that will allow full productivity accounting, using more formal statistical procedures. Regardless of the approach selected, the findings of this paper strongly suggest a need for economists, agronomists and soil scientists to collaborate in integrating approaches in order to provide more robust and informative measures of sustainability.     

中国权证上市日和到期日效应的实证研究

文章选取2007年6月30日之前到期的18只权证为研究对象，以权证所对应的正股价格日收益率、交易量日增长率、日超常收益率比和日超常交易量比等为考察指标，对我国权证的上市日效应和到期日效应进行了实证分析。得出的结论是：在5％显著性水平上，以一天为时间间隔，我国权证的上市日效应和到期日效应均不显著。     

Human resources in Sino-foreign joint ventures: selected case studies in Shanghai,compared with Beijing

This article examines HRM in joint ventures (JVs) in Shanghai compared with those in Beijing using a case-study approach. It focuses primarily on issues relating to labour contracts, rewards and benefits, social insurance, trade unions and personnel policies, and describes current developments in China in each of these areas. In order to place these JV human resource practices in context, we also draw on interviews in state-owned enterprises (SOEs) in Shanghai and Beijing. Taking as a starting point a summary of traditional SOE 'iron rice-bowl' ( tie fan wan ) practices in the management of personnel, we ask to what extent HRM in the present JV sample differs from traditional methods and to what extent 'iron rice-bowl' practices continue despite foreign ownership. The extent to which HR practices in JVs are distinct from those in contemporary SOEs is also examined. We conclude that, although, as one would expect, foreign ownership has modified traditional practice, the degree and extent to which this is true varies widely. There is strong evidence of institutional and organizational continuity in 'iron rice-bowl' practices in both JVs and SOEs. Finally we propose a framework for categorizing the companies investigated in terms of their distance from traditional 'iron rice-bowl' HR practices and proximity to 'imported' practices. This consists of two 'pure' and two hybrid categories: pure 'iron rice-bowl'; hybrid I (predominantly local); hybrid II (predominantly imported): and, finally, pure imported. In this schema, the companies examined do not however group neatly according to whether they are JVs or SOEs.

全面减免东盟关税对中国宏观经济和产业影响的可计算一般均衡分析

Chingem模型是一个中国静态CGE模型.本文在Chingem模型的基础上,分析了2010年中国全面减免东盟原六国关税对中国宏观经济和产业的长期影响.在原模型的基础上,改进了宏观闭合条件.将原来作为剩余量处理的居民消费与居民收入联系起来,使经济增长会作用到居民消费,使模拟结果更加符合实际.研究表明全面减免对东盟的关税有利于我国经济的和谐发展;减少了经济增长对净出口的依赖;促进了进、出口商品结构的升级;促进了服务业的发展,但农业和制造业的一些部门会受到负面影响;制造业的就业会下降,服务业和农业的就业会上升.     

Human Resource Ecosystem and its evolutionary rules

The paper, based on the concept and the elements of human resource ecosystem （HR Ecosystem）, studies the function and structure of HR Ecosystem, introduces the entropy theory to define the content of entropy of HR Ecosystem, constructs the corresponding distinctive model to distinguish the direction of the evolution of HR Ecosystem and the evolutionary entropy model, and applies the models to demonstrate the evolutionary rules of HR Ecosystem. The study shows that the entropy theory can be well applied to the analysis on HR Ecosystem and that it opens up a new field in the research of human resource management and provides a new effective technical method.
