金融关联对上市公司盈余管理的影响研究——代理成本的中介作用

以2013-2016年A股上市公司为样本,采用Bootstrap法检验金融关联对盈余管理的影响以及股权、债权和控制权三类代理成本在两者关系中的中介作用。研究发现：金融关联对应计盈余管理和真实盈余管理均存在着显著的负向影响;股权代理成本及债权代理成本在金融关联与应计盈余管理之间起到部分中介作用,控制权代理成本的中介作用不显著;三类代理成本在金融关联与真实盈余管理之间的中介作用不显著。     

结合全双工与协作干扰的无线网状网物理层安全策略

针对无线网状网中缺少窃听者先验知识不利场景中的安全连接问题,提出了一种结合全双工和协作干扰技术的物理层安全策略。利用全双工通信中的自干扰消除技术和协作干扰技术,提出的安全策略可有效劣化位于信息传播范围内包括潜伏在接收节点附近窃听者的接收性能。为保证信息的安全传输给出了协作干扰节点的选择方法,基于随机几何等数学方法导出了选定路径的安全连接概率表达式。性能分析和仿真结果表明,所提方法与仅基于全双工或协作干扰技术的方法相比,其安全性能有较大提升。     

Who benefit from government-led microfinance projects? Evidence from rural China

Drawing from a unique dataset of 2356 Chinese villages, this paper assesses the anti-poverty effect of the largest government-led microfinance project in the developing world. We find that the project can significantly increase the income level in the targeted villages. The main engine of the project lies in the expansion of access to nonfarm activities. We also highlight the importance of institutional circumstance in the effectiveness of the project. Specifically, a more democratized village with less political connection to local governments reaps more benefits from its participation.     

Coordinating China's economic growth strategy via its government-controlled association for private firms

Scholars in economics and political science argue that one major function of government is to overcome coordination failure in economic development, especially during times of rapid environmental changes. But, how and through what means does the state coordinate firms to follow the changing directions of its economic objectives? This paper focuses on the case of a government-controlled business association, namely the All-China Federation of Industry and Commerce (ACFIC), and shows that the ACFIC may be serving, at least partially, as a means of avoiding the kind of coordination failures that are often associated with policy reform programs in authoritarian regimes like China when the government deems it necessary to radically and suddenly change its policy objectives. It does so by comparing the activities of firms that are members of ACFIC with non-members before and after the world financial crisis of 2008–09 which induced a significant change in government objectives. Before that crisis when priority in government objectives was “outward” (to stave off balance of payments crises that had befallen many other developing countries), ACFIC member firms were able to engage in exports and foreign investment to a greater extent than non-member firms, and even than those whose owners are members of the Congresses or Chinese Communist Party. After viewing the crises in international markets, and government objectives had turned more “inward”, ACFIC members were more likely to focus on domestic sales and investments.     

Estimating the value of political connections in China: Evidence from sudden deaths of politically connected independent directors

This paper estimates the value of political connections by examining stock price reactions to sudden deaths of retired government officials who were acting as independent directors of private firms in China from 2003 to 2012. Employing an event study, we find that, if a private firm loses political connections because of the sudden death of an independent director who was previously a government official, its stock price drops 3.61% on average within ten trading days. After the loss of political connections, we find that it is possible but infeasible for a private firm to reestablish political connections with the government in a short period of time. Moreover, the sudden death of a retired government official leads to a reduction in the economic benefits (e.g., bank loans, tax preference, and government subsidies) obtained by a private firm, which provides a reasonable explanation for the negative stock price reaction after losing political connections.

台资集群网络下内外资企业协同升级困境与出路——以福建省为例的分析

由于集群网络被台资企业主导,使得台资企业协同本地企业产业升级特别是功能升级和价值链升级面临困境。台资集群网络的弱根植性以及由此导致的企业间知识转移受阻是这一问题的根源。因此,提高台资当地根植性,促进本地企业加入多条价值链,培育自己的高级要素,促进内外资企业有效关联与融合,构建有利的区域文化等,已成为理想的策略选择。

An Ecofeminist Narrative of Urban Nature Connection

ABSTRACT

The purpose of this study was to explore meanings, experiences, and perceived impacts associated with an urban nature connection program as narrated by mothers of program participants. “Project Connect”, a charity organization established in 2008, delivers the program investigated in urban parks and green spaces in Toronto, Canada. Drawing on ecofeminism and narrative inquiry, the study reveals a community narrative that depicts how Project Connect serves a group of mothers as an incubator of relationships spanning social and environmental domains, and which enable resistance of status quo forces that shape contemporary cityscapes. Nature connection in this sense is very much a political and cultural process that opens opportunities to challenge but also reproduce aspects of the dominant nature-related discourses. Accordingly, this study prompts consideration of the power of mothers and an ethics of care to transform human-nature relationships, and weaves critical consciousness and cautious re-valuing around the nature narratives we tell.
