Market efficiency and cointegration: Some evidence in Pacific-Basin black exchange markets

This paper investigates the efficiency of the black exchange markets in Indonesia, Malaysia, the Philippines, South Korea, Taiwan, and Thailand. The study applies unit root and cointegration tests to examine black exchange market efficiency of Pacific-Basin countries. The generating process of black exchange rates appears to be a random walk. This is consistent with Gupta (1981) and other foreign exchange rate unit root test studies. Johansen cointegration tests are performed for these black exchange markets together with Japan and Singapore. The results suggest that there is at least one unit root among the black market exchange rates. Hence, black exchange markets are not collectively efficient.     

技术创新对股权结构与企业绩效的中介效应

基于2013-2017年我国277家创业板上市制造业企业数据,采用中介效应检验方法分析股权结构、技术创新与企业绩效三者间的相互关系。结果表明：①第一大股东持股比例与技术创新、企业绩效间均呈显著正相关关系;②股权集中度与技术创新、企业绩效间均呈显著正相关关系;③在股权适度集中的基础上,股权制衡度与技术创新和企业绩效均呈显著正相关关系;④技术创新部分中介了股权结构对企业绩效的影响。研究结果有助于厘清股权结构、技术创新与企业绩效三者间的相互关系,对于我国企业自主创新能力提升及企业绩效可持续增长具有重要意义。     

外部环境、资源拼凑与“军技民用”新产品开发关系研究

基于资源拼凑理论视角,运用扎根理论对传统军工企业“军技民用”新产品开发过程进行探究,并探索外部环境、资源拼凑对“军技民用”新产品开发的作用机理。结果发现：“军技民用”新产品开发包括信息获取、技术选择、技术再造3个过程;资源拼凑是“军技民用”新产品开发的有效措施;外部环境对资源拼凑开发“军技民用”新产品过程具有调节作用。     

Capital liquidity and residents’ consumption decision: An asymmetry analysis of economic prosperity

Among the current literatures that discuss the influence exerted on residents’ consumption behavior by capital liquidity, some often independently decide the demarcation point of the liquidity restriction that affects residents’ consumption behavior, without taking into account when the economy is flourishing whether residents will be influenced by the restriction of the liquidity that their consumption behaviors can not be fully carried out. We introduce a threshold model which varies according to the actual GDP and other financial indicators (money supply, average stock index and balance of bank loans) to discuss residents’ consumption behavior in China under different economic states. The empirical results show that when the economy flourishes or resuscitates, residents’ income of the same period have not notable influence on their consumption, which suggests that residents’ consumption behavior does not considerably change according to the fluctuation of the current income, but conforms with the constant income-life cycle hypothesis. Moreover, two estimated values 0.7504 and 0.8597, as economic boom measures, all fall in the boom stable stage—basically consists with the early-warning index of the macro-economy boom issued by National Bureau of Statistics of China. It shows that the macro-economic boom is not notablely influenced by capital liquidity, so is residents’ consumption behavior.     

汇率波动率与中国对主要贸易伙伴的出口

本文研究汇率波动率对中国向三个主要贸易伙伴美国、欧盟和日本出口的影响。通过协整检验,误差修正模型和Granger非因果检验等方法估计变量间长短期的关系。研究表明,中国向美国和欧盟的实际出口与实际汇率波动率存在长期显著的负相关关系,而中国向日本的出口与汇率波动率无关。短期内汇率波动率只影响中国向美国的出口,对向欧盟和日本的出口没有影响。     

上市公司资产减值方向信息含量研究——来自沪深两市2003年的经验证据

我国新颁布的《企业会计准则第8号——资产减值》规定,存货等已确认的资产减值不得转回。针对新准则对资产减值单向计提的规定,本文从资产减值准备计提方向研究上市公司资产减值的信息含量,发现资产减值的计提方向存在信号显示作用。这表明资产减值准备方向传递了公司未来前景的信息,全面取缔资产减值准备的转回将减少资产减值的部分信息含量。     

高度重视经济运行中的流动性过剩问题

我国经济运行中流动性过剩问题严重 自2003年我国走出通货紧缩的阴影后,经济就步入了新一轮增长的周期,连续4年国内生产总值保持两位数的增长,而物价水平却控制在1.2%～3.9%的涨幅内.     

基于价值链思想的作业成本法研究

首先,论述了基于价值链思想的成本管理方法如何弥补传统成本管理方法存在的诸多局限性;而后,对基于价值链思想成本管理的具体应用——作业成本法(ABC)进行研究,对其传统模型加以改进;同时,对存在的主要问题构建简单数学模型加以解决。     

生产和服务提供过程的确认及其控制

GB/T19001-2000《质量管理体系要求》中7.5.2"生产和服务提供过程的确认"是质量管理体系运行中控制难度大且极易出现问题的过程。本文结合实践,从识别需确认的生产和服务提供过程、开展生产和服务提供过程的确认活动及对确认后的过程实施控制等三个方面作出了阐述。     

组织间合作创新:基于组织形式的梳理

在专业化分工越来越深化的背景下,创新很难由单个组织实现.通过整合组织间的分布性知识更易实现创新.在组织间合作创新中,组织形式的选择由于涉及路径依赖、知识转移、公平性等问题而成为合作创新成功的障碍.本文认为,在合作创新中,组织形式的选择应当考虑一体化程度、网络中心性、治理机制和公平性等因素,以促进组织问的合作创新.
