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。     

退休老年人身体形态与力量素质相关关系的研究

近年来老年人的身体健康现状日益成为人们关注的焦点问题之一,为了对退休老年人的身体健康状况有进一步的了解,对58-68年龄段退休老年人进行身体形态和力量素质的测试。研究发现身高与握力（r=0.659）、体重和握力（r=0.655）均有显著相关性,且呈正相关趋势,身高与体重（r=-0.243）呈负相关。因此在适度原则下,应加强以力量素质为主的体育锻炼,其对于提高身体素质,增进健康有非常重要的意义。     

Religious pluralism and religious participation: a median-based approach to the non-substantive problem

Sociologists of religion have long been interested in the interaction between religious pluralism and religious vitality. Previous empirical studies approach this theme by drawing on data of denominational participation rates across geographical units, investigating the property of association between the quantity of one minus the Herfindahl–Hirschman Index (religious pluralism), and the total religious participation rate (religious vitality). However, this association could be theoretically spurious. Taking advantage of the median’s statistical property of being less sensitive to the variations of extreme values, this study proposes to apply the median instead of the arithmetic summation of religious participation rates to measure geographical-unit-level religious vitality. This method is illustrated by analyzing the New York State census of religion 1865 and the U.S. county survey 1990.
