The research of Chinese karst ecological hydrology

1. Introduction The area of carbonate rocks protruding through the soil level in China is 9.07*105km2. According to the area of carbonate rocks stratum protruding through the soil level, it is 2.06*106km2. With the buried carbonate rocks stratum of the different depths, its total area can reach 3.443*106km2, ap- proximately accounting for 1/3 of the national terri- torial area. Chinese carbonate rock is mainly distributed to the south of the latitude belt of Tianshan Mountain – Yinshan Moun…

Utilizing Printed Media to Understand Desired Leadership Attributes in the People's Republic of China

Using news media as a reliable source, we content analyzed stories on business leaders in two major official Chinese newspapers in three different time periods over the past 20 years. Results show that the reform has brought an increase in stories of business leaders, and in coverage of the desirable leadership attributes relating to Confucian virtues, communist ideologies, and modern management philophies. The results suggest that, by publicizing and adorning specific leaders in both government and business sectors in the official media, the government reinforces the traditional values that are consistent with communist ideologies, and at the same time, it also introduces Western management values to suit the current needs of the society. The results of our study echo the findings of empirical studies on Chinese values that used data collected using other methods. We therefore encourage future research to use the printed media as a potentially valuable source of data for tracking changes in social phenomena in a society over time.     

政府职能转型与媒介效应述评——以电子政务为例

在由计划经济向市场经济转型过程中,我国政府职能正加速向“服务型”政府转变。适应媒介融合发展的趋势,电子政务在各级政府部门方兴未艾。媒介产业日益融合的今天,电子政务立足于互联网平台,涵盖了微信、微博、各类手机APP等多种媒体形式。完善的电子政务服务有利于提升公众对政府的信任和公共服务的满意度。当前电子政务媒介效应经验评价方法主要有层次分析法（AHP）、结构方程法（SEM）、因子分析和DEA方法,但这些方法在指标体系选择和测评方法的适应性方面还存在不足,努力构建普遍适应的、数据可获取性强的电子政务媒介评价方法体系是今后该领域研究的方向。     

我国报业集团跨媒体经营研究

报业跨媒体经营是指报业企业为了充分利用自身的资源,开发并涉足其他诸如图书、杂志、广播电视、网络等媒体市场。随着我国报业集团化进程的快速发展,报业集团跨媒体经营的步伐也在加快。跨媒体经营既可以通过单体繁殖实现,也可以通过资本运作实现,但无论哪种方式都不能理所当然地被认为,跨媒体经营是传统媒体实现可持续发展的万金油。文章利用经济学原理分析了我国报业集团跨媒体经营的动因以及目前报业集团跨媒体经营存在的问题,并提出了针对性的政策建议。     

养老保险媒体宣传的差异及助推效应分析

借助文本分析技术,基于国家级与省级官方媒体大数据,构建了媒体宣传指数,并分析其对养老保险的助推效应。研究发现,媒体对不同支柱养老保险的宣传重视差异较大,对第二和第三支柱关注较少,且在中西部地区尤为突出;媒体宣传对养老保险发展有明显的助推效应,能扩大参保广度,但对参保深度的提升有限。据此,政府应加大第二和第三支柱的媒体宣传力度,促进养老保险三支柱的平衡发展,筑牢全民养老保障基础。

Does Social Media Get Your Attention?

The author investigates how social media affects stock prices and post–earnings announcement drift in response to companies’ quarterly earnings announcements. Using quarterly earnings data as well Twitter and StockTwits data, the author utilizes Twitter volume and a residual methodology to generate an attention proxy that is orthogonal to the growth of Twitter accounts. The author finds that the new attention brought by social media after the earnings announcements positively affects the cumulative abnormal returns. Further, even companies reporting bad news can still have positive immediate cumulative abnormal returns if they attract enough attention from investors after an earnings announcement. The new attention effects are different in both magnitudes and statistical significance between social media popular and unpopular industries.
