跨国公司对我国产业组织的影响

跨国公司的进入已经成为我国社会和政府最关心的问题之一。为了分析跨国公司对我国产业发展的促进效应和对企业发展的挤出效应,我们需要对外商直接投资和跨国公司的行为对中国产业组织进行全面的经济分析。文章主要分析跨国公司进入我国市场对我国的产业组织方面的影响。     

外向型管理审计存在的问题及开展的必要性

外向型管理审计在上世纪60年代就开始受到西方学界和CPA们的关注,它的出现是审计鉴证职能由财务鉴证向管理鉴证发展的必然结果。近二、三十年来,外向型管理审计在西方发达国家经济管理、工商管理和行政管理中发挥着越来越重要的作用,其实务也在持续不断地发展着,但在我国,外向型管理审计的理论研究还处于起步阶段,而在实务中也未得到应有的重视,因此近期在我国开展外向型管理审计还存在一定的问题;而另一方面,在市场经济体制和观念日益深入的今天,受托代理责任也在日益明确而且复杂化。因此,我国发展以鉴证受托人受托管理责任的经济、效率和效果等目的为己任的外向型管理审计已经成为现实的迫切要求。     

When are outside directors effective?

This paper uses recent regulations that have required some companies to increase the number of outside directors on their boards to generate estimates of the effect of board independence on performance that are largely free from endogeneity problems. Our main finding is that the effectiveness of outside directors depends on the cost of acquiring information about the firm: when the cost of acquiring information is low, performance increases when outsiders are added to the board, and when the cost of information is high, performance worsens when outsiders are added to the board. The estimates provide some of the cleanest estimates to date that board independence matters, and the finding that board effectiveness depends on information cost supports a nascent theoretical literature emphasizing information asymmetry. We also find that firms compose their boards as if they understand that outsider effectiveness varies with information costs.     

再谈会计等式的变化

会计恒等式完整地反映了企业财务状况和经营成果及其形成过程,是会计核算的理论依据,由于受会计计量模式、会计核算范围的影响,会计等式亦发生不同的变化,对企业资产价值产生结果,并且决定其提供的会计信息是否有用,本文对这一问题进行了初步探讨。     

南橘北枳:A股市场的经济关联与股票回报

本文系统检验并比较了中国A股市场中行业动量、区域动量、供应链动量以及科技关联动量等经济关联动量的显著性及预测周期。本文发现,中国股票市场中经济关联因子呈现出与美国股票市场不同的规律,在月度层面行业动量显著,而科技关联因子只在周度上具有显著的预测能力。进一步分析科技关联动量发现,中国股票市场中科技关联因子能预测目标公司未来1-3周的股票收益和未来基本面的变化,据此构建的多空策略能够产生周度0.16%的超额收益(年化8.67%);机制检验发现,科技关联因子预测期短的原因是由于中国股票市场中存在较多具有博彩倾向的散户投资者;有限注意和市场摩擦两个机制检验证明科技关联动量源自错误定价。进一步检验发现,科技关联动量在国有企业和创新政策颁布后更加显著。本文补充了现有A股市场的动量研究,有助于理解中国股票市场规律、提升资本市场有效性。     

Anti-corruption,government subsidies,and investment efficiency

The problem of corruption in socio-economic development has long been a focus of academics and practitioners. To address this concern in China, the 18th National Congress of the Communist Party of China instituted a new anti-corruption policy. In this paper, we examine the impact of this recently enacted anti-corruption policy on the investment efficiency of subsidized enterprises from the perspective of government subsidies. We conclude that government subsidies have a significant positive impact on the overinvestment behavior of enterprises and that the anti-corruption work done by the government has effectively restrained the excessive investment behavior of government-subsidized enterprises. Further, we find that the anti-corruption policy is more effective in restricting overinvestment in subsidized state-owned enterprises than in non-state-owned enterprises. We examine the impact of the anti-corruption policy on excessive investment caused by government subsidies and enrich the body of research related to investment efficiency. We also provide empirical support for further research on the anti-corruption policy at the macro-market and micro-enterprise levels. The findings highlight the need to establish new cooperation between government and enterprises, to rationalize the distribution of administrative resources, and to promote the sustained and healthy development of the national economy.     

Excessive Financial Support,Real Estate Development and Macroeconomic Growth: Evidence from China

ABSTRACT

Using monthly panel data for China’s 30 provinces from 2007 to 2017, this article analyzes how level of financial support affects the interplay between real estate development and macroeconomic growth. Based on a threshold model, the results suggest that housing price increases substantially impede economic growth, but there is no significant threshold effect for the sample as a whole. On investigating regional cross-sectional variations, we found that local economic situation clearly impacts on this effect, with significant threshold effects detected in subsamples. While housing price may have positive influences on economic growth in the mid-west subgroup with appropriate financial support, more developed regions returned contrary results.

一种新的SC—FDE系统粗定时同步算法

定时同步是单载波频域均衡(SC-FDE)系统的一项关键技术,其中的粗定时同步算法决定着同步收敛速度,由Schmidl和Cox提出的传统算法中出现的测度峰值平台影响着粗同步的精度与速度。通过训练符号格式的重新设计,利用其中4个相同部分良好的相关特性,提出了一种基于特殊训练符号的粗同步算法。仿真结果表明,在高斯白噪声信道和多径衰落信道条件下,新算法定时偏差估计的方差和均值接近于理论值,粗定时同步能够精确地完成,较好解决了测度峰值平台问题。
