建设工程信息集成管理系统研究

工程项目建设与管理过程中会产生大量的物化的材料——建设工程信息。静态信息资料组卷归档后将成为建设工程项目的档案资料，为工程检查验收及日后的改建、扩建、维修、管理等方面提供极其重要的依据，动态信息则为工程建设过程的管理与决策提供强力支持，而这一切都建立在对建设工程信息的有效管理基础上，从了解建设工程信息特点入手,分析客户的需求，构筑管理系统构架,开发了相应的功能模块，并付诸了实施。     

石油储量价值评价中外部成本级差模型的设计与检验

石油资源的价值评价中,被重点讨论的成本级差因素由4个因素组成,其中有一类相对于油藏本身而言是外部性的因素,称为外部成本级差因素.在分析外部成本级差因素的组成因子之后,建立能够对之进行测算的数学模型,并就两个油田的实测数据给出计算结果.

Benefits of Downward Earnings Management and Political Connection: Evidence from Government Subsidy and Market Pricing

This paper examines the role of downward earnings management and political connection on the receipt of government subsidies and market pricing of subsidies. Using subsidies data hand-collected from Chinese listed firms over the period 2004–2014, the results show a significantly positive association between downward earnings management and the receipt of government subsidies. The results also reveal that a firm's political connection is conducive to securing subsidies for poor performers, but not for good performers. Market pricing analyses demonstrate that share markets value subsidies positively in general, but the effect is ameliorated in firms conducting downward earnings management. No discernible difference is found between the market pricing of subsidies received by firms with political connections and those without.     

The Effect of Ultimate Ownership on the Disclosure of Environmental Information

This study empirically examines whether environmental information disclosure (EID) is influenced by the characteristics of a firm's ultimate owners. Based on the EID of publicly listed firms in China, we qualitatively measure the quality of EID of each firm and link those quality scores to firm characteristics to understand the determinants of EID. We further link the EID scores to market valuation of the firm through the Ohlson valuation model to understand whether the market appreciates EID. Our results show that EID is more likely for government‐controlled firms, firms with less hierarchy in their ultimate ownership and firms with more discrepancy between voting rights and cash flow rights. Our results also indicate that the stock market appreciates environmental issues and that EID itself, as well as disclosure quality, is associated with a higher market valuation. Our results still hold with the endogeneity issue controlled.

Total Factor Productivity and Energy Intensity: An Empirical Study of China’s Cement Industry

China is the largest cement producer and consumer in the world. The cement industry’s rapid growth has led to a large demand of energy. This study reviews China’s cement industry in terms of energy intensity and examines the effects of technological progress on energy intensity. It also discusses the feasibility of achieving China’s energy reduction targets. We employ the Granger causality test and find that the total factor productivity or technological progress causes the energy intensity of the cement industry. Impulse responses analysis also proves that in the long run the technological change contributes to the decline in energy intensity of cement production.     

前瞻性人格、职业适应力与员工职业成长:工作自主性的调节作用

研究基于职业建构理论和情景交互理论,探讨职业适应力作为中介变量,工作自主性作为调节变量在前瞻性人格影响个体职业成长(内在职业成长与外在职业成长)过程中的作用.通过对问卷数据的分层回归分析,研究结果表明:前瞻性人格对个体的内外在职业成长有显著正向影响;职业适应力在前瞻性人格与内在职业成长间表现出部分中介作用;工作自主性在前瞻性人格与外在职业成长关系间的调节作用更为显著.     

以政府职能转变推动收入分配改革

收入和财富分配的不平等一直是中国改革发展中的重要问题。针对中国经济的特点,可以从政府改革的角度来研究如何更好地进行收入分配改革。地方政府主导推动地方经济的做法对收入不平等的扩大起了重要作用,加快政府职能转换,是使收入分配改革真正落到实处的破局之处,也是实现收入分配合理化可行的第一步。要改变地方政府的经济职能,降低它直接参与基础设施的程度,改革地方土地财政,建立垂直管理机构,以分散它的一部分经济管理职能,为收入分配改革打开空间。
