MANAGING CHANGE IN SUPPLY CHAINS: A PROCESS COMPARISON

The coordination required to successfully implement supply chain initiatives suggest that supply chain management change processes may possess some unique characteristics. Yet, empirical studies are scarce to support this logic. Using an empirical design and data obtained from managers, and drawing largely from Lewin's change process conceptualization, this study compares the process of supply chain management change to non‐supply chain management change. Further investigation into monitoring and control of supply chain management change is advised.     

中国经济增长中的结构平滑转移

本文应用考虑结构平滑转移的单位根检验方法,对中国22个主要的宏观经济变量进行了检验,结果表明其中半数能够拒绝单位根假设,可以用非线性确定趋势过程加以描述。除就业人员序列外,其余变量均不具有显著的非对称调整特征。实际GDP序列在改革开放初期发生了一次结构渐变,稳态增长率由原来的4.4%逐步提高到7.2%,标志着我国经济整体上已经平稳过渡到了一个更高的发展阶段。     

我国如何应对国际资本对华流动的新变化

90年代中后期以来，国际对华投资呈现出新的特点。本较具体地分析了国际资本对华流动的新变化，在我国加入WTO后的新形势下，就如何有效地利用国际资本来促进我国经济的健康发展提出自己的看法。     

政府采购制度变迁的双层次互动进化博弈模型

宏观层次和微观层次的博弈具有互动性,政府、财政部门和微观主体的博弈行为可以用这种互动博弈联系起来。正是宏观层次中央政府与各级财政部门、微观层次各级财政部门和微观主体的重复博弈,而使得双层次互动博弈模型为一个动态的模型,从而得到了进化安定策略(ESS),达到进化安定均衡。     

Audit opinion improvement and the timing of disclosure

Companies have been found to report positive information more quickly than they report negative information (i.e., good news early, bad news late). This paper investigates the potential impact of audit opinion change on the timeliness of financial disclosures, with improvements in audit opinion considered to be “good news.” We take both the direction and the magnitude of audit opinion change into consideration, with magnitude measuring how far the opinion is from an unqualified opinion (i.e., an unqualified opinion with explanatory paragraph is closer to an unqualified opinion than a qualified opinion is). We find that firms experiencing an improvement in their audit opinions disclose their financial results earlier, while those with audit opinion deteriorations report their financial results later, and that these effects were related to the magnitude of the opinion change. What's more, there is an asymmetric response to good audit opinion news vs. bad audit opinion news, with bad audit opinion news having a larger effect on earnings timeliness than the effect on earnings timeliness of good audit opinion news. Overall, our results support the “good news early, bad news late” notion. Finally, we also find that overall earnings timeliness has improved in China since the enactment of new reporting regulations in 2006.     

高等教育融资的制度变迁与融资对策

我国的国情是“穷国”办了世界最大规模的教育,教育融资不足的问题是制约我国公立高等教育发展,乃至影响整个经济发展和社会进步的极为重要的课题。针对公立高等教育的准公共产品属性,我国公立高等教育融资需要国家、社会、学校及学生多主体同步推进,逐步加以解决。国家应该承担起教育投入的主要责任,合理规避高校贷款的融资风险;作为有益补充,学校可以采用稳步推进BOT融资等市场化融资手段,同时建立和完善“资本投资式”的助学贷款机制,减轻政府的财政负担。     

经济全球化与中国工业结构变化

理论分析显示经济全球化能通过固定资产投资、制度变迁和劳动力等因素引发中国工业结构变化。运用协整分析和ECM等方法实证检验显示长期内经济全球化增长1%将促使我国工业结构变化0.27%,固定资产投资、制度变迁和劳动力均能促进我国工业结构变化,而短期内经济全球化和劳动力可能制约工业结构变化。     

化石能源耗竭与气候变化约束下的经济低碳转型

本文构建了一个包含产品生产、技术研发、新能源生产和温室气体减排四个部门的内生增长模型;并运用最优控制理论,研究了在化石能源耗竭与气候变化约束下,经济低碳转型中的一系列关键变量的长期行为方式和中短期平衡增长路径;进而刻画了劳动力在各部门间的配置和转移、化石能源价格、排放空间价格对能源结构、碳强度、消费、单位劳动碳减排量、单位劳动产出等变量的影响机制;同时揭示了运用一些政策工具实现经济低碳转型的时机选择。     

劳动力规模、组织成本与农业生产合作组织演变——基于民国以来的历史分析

中国农业生产合作组织的演变具有显著的周期性特征和地域性差异,但是已有研究只是选择性地关注短期内农业生产合作组织的效率问题及其影响下的去集体化过程,或者只是简单地强调国家强制性制度安排下的合作化过程。本文认为,不同社会经济条件下的劳动监督成本和协调成本差异决定组织成本差异,组织成本差异决定各种农业经济组织的相对效率结构,因而决定农业经济组织的周期性演变及其多样化特征。进一步的研究表明:战争、气候灾难等消极性因素和人口死亡率下降、人口寿命延长等积极性因素是劳动力规模及其劳动监督成本波动的诱因,因而是农业经济组织长期性演变的终极决定因素。利用1911-2011年中国省级、县级的各类人口和合作社数据,本文从宏观层面初步验证了这种观点。
