地方政府债务风险压力对地方国企并购行为的影响——来自A股市场的证据

在中国政府高度重视地方政府债务风险控制背景下,作为地方国企实际控制人的地方政府所具有的债务风险压力,是否会影响地方国企实施并购行为?地方国企实施并购行为后又会产生怎样的经济后果?本文基于2014-2019年A股地方国有上市公司并购行为样本,实证检验了地方政府债务风险压力对地方国企并购行为的影响及其效应.研究发现,与地方政府债务风险压力较低地区的地方国企相比,地方政府债务风险压力较高地区的地方国企选择并购战略的可能性较高,并购完成后套现的规模也相对较高.地方政府债务风险压力对地方国企并购后取得的短期并购绩效显著较好,但对长期并购绩效的影响显著较差.深入研究发现地方政府债务风险压力主要来自于由隐性债务风险构成的压力.本文的研究既有助于深入理解地方政府债务风险压力影响地方国企并购行为的机制,也为监管部门调整国企并购套现、以及地方政府债务风险化解的相关政策提供了依据.     

地方政府债券法律问题之反思

地方政府债券存在《预算法》上的障碍,地方政府也难以成为债券的最终责任人。缺少完善的信息披露机制与权力制约机制,因而很难保证地方政府项目决策的科学性和对项目资金的法律约束。进一步理顺中央与地方的关系是解决问题的根本出路。     

长期资产减值准备:盈余质量与市场反应

对2001～2006年旧资产减值会计制度实施期间的相关数据进行检验,本文发现长期资产减值准备所产生的应计盈余明显地降低了会计盈余的质量。按长期资产减值准备的应计盈余所构建的逆向套利组合能获得显著的超额报酬率,长期资产减值准备的应计盈余与超额回报负相关,说明市场不能识别长期资产减值准备对会计盈余质量的影响。本文的结论支持新会计准则禁止长期资产减值准备转回的规定。     

城乡居民个人慈善捐赠行为差异实证研究——以辽宁省为例

借助CATI随机调查辽宁省14市及所辖农村中811名居民,采用独立样本T检验、单因素方差分析来研究人口统计学因素对个人日常捐赠行为和特殊捐赠行为的影响。研究发现：文化程度、职业、收入和政治面貌等因素对城乡居民的日常捐赠行为和特殊捐赠行为均有显著影响;性别、年龄和婚姻状况等因素对城市居民的特殊捐赠行为有显著影响,且不同年龄城市居民间的日常捐赠行为差异显著。最后,提出促进居民慈善捐赠的建议。     

Diffusion of mobile telephony: An empirical study in Taiwan

Mobile telephony penetration is a major indicator of mobile telephony diffusion. Taiwan had a mobile telephony penetration of 108% in 2002, ranking first in the world. This study analyzes this accelerated diffusion in terms of growth model and determinants of the diffusion rate. To eliminate the inherent uncertainty associated with choosing the optimal growth model, this study compares the performance of three conventional models, namely Gompertz, Logistic and Bass, to identify the most appropriate model, and to distinguish the forces driving the diffusion rate. Empirical results indicate that the most appropriate model is the Logistic model. Network externalities, which this study shows to be the same as the imitation effect in the Bass model, explain the superiority of the Logistic model. Moreover, market competition, which markedly reduces service prices, is identified as a primary driver of the diffusion rate of mobile telephony in Taiwan. Economic conditions, technological innovation and number of operators are insignificant factors. Finally, mobile telephony is a substitute for fixed-line telephony in Taiwan.     

The effects of ownership concentration and corporate debt on corporate divestitures in Chinese listed firms

This study examines how ownership concentration and corporate debt impact corporate divestitures in China. Corporate divestitures reduce the asset base of a company and the opportunity for expropriation by majority shareholders. In emerging economies, weak legal institutions, combined with equity ownership concentration and high corporate debt, allow majority shareholders to avoid such disciplines. Consequently, the relationship between these governance mechanisms and divestiture activity exhibits a pattern that is different from that in developed economies. Using archival data collected from 1,210 Chinese listed companies during 1999–2003, we found that ownership concentration by the largest shareholder depressed corporate divestitures both in state-controlled and in non-state-controlled firms. The negative effect of corporate debt on divestitures only existed for state-controlled firms. Our finding provides corroborating evidence for principal–principal conflicts in emerging economies. It suggests that corporate strategy in these countries can be better explained by taking into account the unique agency problems that are prevalent in these economies.

地方政府公信力：影响区域经济发展的重要因素

作为一种区域软实力,地方政府公信力是影响区域经济发展的一个重要因素。良好的政府公信力能够为区域经济发展营造公平的市场竞争秩序、促进区域内社会稳定发展以及塑造良好的区域形象。而目前我国一些地方政府公信力存在下降的趋势,在严重影响社会信用环境及地方投资环境的同时,也妨碍了政府与公众之间良好的互动关系的建构,增加了政府管理成本,制约着地方经济的发展。因此,有必要提高政府公信力,为区域经济发展营造一个良好的诚信环境     

Discrete-order admission ATP model with joint effect of margin and order size in a MTO environment

Swarming demands and seasonality periodically induce a stringent capacity problem in the made-to-order (MTO) B2B environment. Desirable order admission is a tactic with minimal application cost for handling this problem. A real-time order admission problem with limited major-customer population and batch-size demand with heterogeneous distributions is modeled as a dynamic and stochastic knapsack problem. The optimality of the Markovian deterministic reward-threshold policy is verified. Optimal policy, basic policy, and the capacity rationing method are compared in the designed experiment. The numerical results suggest great potential for increasing profit using the optimal order admission policy for MTO businesses.
