POST‐PRIVATIZATION OWNERSHIP AND FIRM PERFORMANCE: A LARGE META‐ANALYSIS OF THE TRANSITION LITERATURE

This paper aims to perform a large‐scale meta‐analysis of the relationship between post‐privatization ownership and firm performance in Central and Eastern Europe and the former Soviet Union. Baseline estimation of a meta‐regression model that employs a total of 2,894 estimates drawn from 121 previous studies indicated the superior impact of foreign ownership on firm performance in comparison with state and domestic private entities. Furthermore, the estimation of an extended meta‐regression model that explicitly controls for the idiosyncrasies of transition economies and privatization policies strongly suggested that differences between countries in location, privatization method, and speed of policy implementation strongly influence the link between post‐privatization ownership structure and firm performance. We also found that these factors not only cause a remarkable gap between countries in terms of ex post improvement in firm performance but also significantly affect the interrelationship between foreign investors, domestic outsider owners, and firm managers, and the relative superiority of various domestic outsiders. Conclusive evidence of the harm caused to ex post firm performance by voucher privatization is one of the most noteworthy empirical findings in this paper.

The influence of CSR on firm value: an application of panel smooth transition regression on Taiwan

Previous studies on the relationship between corporate social responsibility (CSR) and firm value generally belong to one of the two opposing schools of thought: the social impact hypothesis and the shift of focus hypothesis. This study, however, proposes that the relationship between CSR and company value is non-linear and neither wholly positive nor negative. We employed the corporate social responsibility index (CRSI) to test this hypothesis. The panel smooth transition regression (PSTR) model was used to analyse listed Taiwanese firms from 2010 to 2012 and calculate the value transition threshold of CSR, using CSRI as the transition variable. We then applied PSTR to determine whether CSRI shows a two-regime, non-linear relationship, as inferred by our model. Empirical findings show that the threshold value of CSRI is 13.082, thus, we concluded that investment in CSR does not contribute to enhancing company value until it exceeds the value transition threshold.     

资源枯竭型城市经济转型中的文化问题

资源枯竭型城市的经济转型是一个世界性普遍关注的问题.本文从文化的角度入手,着重讨论了资源枯竭型城市在经济转型中存在的诸多文化问题,并设计了"纳克斯怪圈",以演示经济衰退和文化衰退之间所形成的恶性循环.然后探讨了文化建设与经济发展的关系.本文认为,资源枯竭型城市的经济转型,不仅是一个经济问题,也是一个文化问题,加强文化创新可以促进经济转型的顺利进行.     

基于土地利用转型的生态服务交叉敏感性分析——以雄安新区为例

以雄安新区为研究区,将1998年、2008年、2017年3期遥感影像作为数据源,结合土地利用转移矩阵及转型特征信号识别方法,揭示土地利用转型特征,并应用生态系统服务价值测算修正模型及交叉敏感性系数模型,探讨雄安新区生态系统服务价值对土地利用转型的敏感程度。结果表明:(1)雄安新区地类转移主要发生在耕地向建设用地和水域的转移。(2)土地利用转型特征信号主要表现在水域、林地与耕地之间的转移。(3)生态系统服务价值逐年缩小,地均ESV低值区的变化率普遍偏高,其空间分布呈反向趋势。(4)水域、湿地、耕地和建设用地向其他地类转型对ESV的影响均较为敏感。研究结果可为如何在科学管理土地利用的同时实现生态服务功能的延续和提升提供借鉴。     

The Efficiency of Input Use During the Early Transition in Hungary

This paper uses Hungarian firm level panel data for the agricultural and light manufacturing sectors during the early years of the transition to investigate differences and changes in the efficiency of input use. Programming techniques measure scale and technical efficiency. The simple radial measure, as well as two other measures that account for programming slacks, are used. The results show little wastage of materials and labour, but inefficient use of energy and capital, which suggests that the development of input markets was uneven. The price liberalisation of 1989 widened efficiency differences, especially in agriculture, but this sector recovered quickest, actually using capital more efficiently by 1991. However, energy efficiency levels were low in the period of soft budget constraints and fell still further after the reforms, suggesting that a free market for energy was not established, particularly in agriculture.
