Nationality,social network and psychological well-being: expatriates in China

Expatriate social networks constitute an under-emphasized area in expatriate literature. The current study contributes to the expatriate adjustment literature by empirically testing the relationship between expatriate personal networks and psychological well-being. The current study also investigates the hypothesis that expatriates from different cultural backgrounds will establish different social networks and adjust differently in China. A survey of 166 expatriates in China from North America, Europe and other countries in Asia showed significant support for the hypothesis that expatriate network characteristics have a direct and significant influence on expatriate psychological well-being. In addition, as predicted, expatriates in China from different cultural backgrounds (Overseas Chinese, other Asian, North American and European) established personal networks with different characteristics.

State ownership and firm performance: Empirical evidence from Chinese listed companies

While the relationship between state ownership and firm performance has been widely researched, the empirical evidence has provided mixed results. This study applies panel data regression techniques to 10,639 firm-year observations of non-financial Chinese listed firms during 2003–2010 to examine the relationship between state ownership and firm performance. The results show that state ownership has a U-shaped relationship with firm performance. The Split Share Structure Reform in 2005–2006 played a positive role in enhancing the relationship between state ownership and firm profitability ratios. Although state ownership decreased significantly after 2006, it remains high in strategically important industry sectors such as the oil, natural gas and mining sector and the publishing, broadcasting and media sector. The findings reveal that a higher level of state ownership is superior to a dispersed ownership structure due to the benefits of government support and political connections. The Split Share Structure Reform made previously non-tradable shares legally tradable, improving corporate governance and reducing the negative effect of non-tradable state shares.     

中国大陆上市公司的时空现状及其可持续发展研究

首先阐述了中国大陆证券市场的发展历史，分析了中国大陆上市公司的发展态势。从中国大陆各省区(省、直辖市、自治区)、六大经济区、三大经济地带入手，探讨了中国大陆上市公司的空间分布格局及其分布重心的移动轨迹，指出中国大陆上市公司的空间分布格局是由区域上市公司数量、土地面积、经济发展水平和产业结构发展状况等诸多因素所造成的。最后对上市公司的可持续发展进行了研究，旨在为中国大陆区域上市公司的相对均衡发展和可持续发展提供科学依据，以促进中国证券市场和国民经济的持续发展。     

Stock price reactions to earnings announcements: evidence from Chinese markets

We examine the stock price reactions to changes in earnings per share (EPS) in the Chinese stock markets. We find that domestic A-share investors do not correctly anticipate the changes in earnings and fail to adjust new earnngs information quickly, but international B-share investors can predict earnings changes better than A-share investors. As a result, abnormal returns (ARs) can be obtained by trading on the earnings information, but for A shares only. An explanation is that most A-share holders are individuals with short-term investment horizon while most B-share holders are large institutions that trade on more detailed and accurate financial information not immediately available to A-share holders.     

户主受教育程度对家庭风险性金融资产选择的影响研究

利用中国家庭金融调查数据（CHFS）,通过Probit和Tobit模型解释户主受教育程度对风险性金融资产选择的影响,并对内在传导机制进行中介效应、调节效应分析。结果显示：户主的受教育水平对风险性金融资产的参与度和持有比例有积极影响,地区、城乡间影响差异明显,风险态度和家庭收入对户主受教育程度影响金融资产选择存在中介和调节效应。研究结论对进一步优化家庭金融资产配置有一定启示意义。     

中国城市公园的标度律特征分析

科学研判城市公园面积与人口规模的关系,有利于 客观认识和指导城市的可持续发展。采用1996—2019年中 国291个地级及以上城市公园面积与人口规模数据,探究二者 之间的标度关系及其标度因子的时空演化规律,进而采用基于 标度律的公园规模修正模型度量各城市公园面积达到预期值的 程度,并对规模修正指标和人均公园面积进行比较分析,得到 如下结果。1)我国公园面积与人口规模整体呈亚线性规模缩 放关系,公园具有显著规模效应,符合城市标度律特征;时间 上呈现亚线性-超线性-亚线性的阶段性波动演变特征,空间 上分异明显：华南接近线性标度关系,华中、东北、华北、西 南呈典型亚线性关系,华东、西北呈亚线性,但标度因子偏离 度较大。2)大城市在人均公园面积排序中相对靠后,在考虑 规模效应后,排名普遍提高,说明规模修正指标能在消除人口 规模影响的基础上,有效衡量不同规模城市公园面积的水平。 标度律视角下的城市公园规模测度能够为城市人口管理和公园 面积发展的决策提供科学指导,为不同规模城市公园建设提供 可借鉴的比较标准,促进公园与人口的协调发展。

增长极战略的实现机制与中国实践模式的重构

增长极理论是20世纪50年代新古典区域均衡发展理论遭遇危机之后的新选择,但自其诞生以来由于缺乏成功案例的支持而备受争议。我国区域非均质、不平衡使得增长极模式备受推崇,但在发展中同样遭遇困境。鉴于理论与现实鲜明的反差,以增长极的实现机制为切入点剖析了该理论的不足,指出我国三大增长极在实践中存在政府依赖刚性、自我发展能力弱、关联效应差等问题,认为完整的增长极实现机制应包括形成机制、运行机制和扩散机制,并从这三大机制入手重构了中国增长极的实践模式,提出相关政策建议。
