农地流转、要素配置与农户生产效率变化

研究目的：基于农户收入视角,使用2017年和2019年中国农村家庭调查数据,分析农地流转对农户要素配置及生产效率的影响,以期为推动农户经济高质量发展提供决策参考。研究方法：面板Tobit模型、DEA模型和控制函数法。研究结果：（1）农地转入提高了农户的技术效率,但对分配效率没有明显改进;（2）农地转出抑制了农户的技术效率,提升了农户的分配效率;（3）当经营规模达到13.156亩,农户实际经营规模与技术效率之间出现“倒U”型曲线的拐点;（4）从农业部门来看,农地转入显著提高了农户在传统生产环节使用机械的可能性;从非农部门来看,农地转出对劳动力迁移具有显著的正向促进作用。研究结论：农地流转较为明显地提升了农户主要经营部门的生产效率,但是对于跨部门生产效率提升并不明显。为提高农民收入与农户生产效率,需协同推动农业生产手段改进和劳动力转移规模相适应的农地流转。     

G-H-M理论扩展与国有企业产权改革

本文通过扩展G—H—M理论，将剩余控制权区分为名义剩余控制权与实际剩余控制权．强调实际剩余控制权与剩余索取权存在高度互补性，据此分析国有企业内在机制的缺陷，一方面国有产权的实际剩余控制权与剩余索取权分离，另一方面名义剩余控制权缺乏完全性，因而国有企业的改革方向是以消除制度设计内在矛盾为目标的产权改革。     

不良贷款约束下的中国银行业效率——基于方向性距离函数的实证分析

运用方向性距离函数方法测度中国银行业2000～2006年包含不良贷款的技术效率及规模效率得出,在平均意义上,考虑不良贷款后,国有和股份制银行在生产前沿上的数目增多,中国银行业的效率水平提高并且效率值变化近似于V字型;在最大化减少不良贷款和投入同时增加好产出时得到的效率值较高;中国银行业处于规模报酬递减区域,但从长远看,规模效率有上升的趋势。     

Random walk and efficiency tests in the Asia-Pacific foreign exchange markets: Evidence from the post-Asian currency crisis data

This paper empirically tests the random walk and efficiency hypothesis for 12 Asia-Pacific foreign exchange markets. The hypothesis is tested using individual as well as panel unit root tests and two variance-ratio tests. The study covers the high (daily) and medium (weekly) frequency post-Asian crisis spot exchange rate data from January 1998 to July 2007. The inferential outcomes do not differ substantially between the unit root tests and the variance-ratio tests when using daily data but differ significantly when using weekly data. With the daily data, both types of unit root tests identify unit root components for all the series and two variance-ratio tests provide the evidence of martingale behavior for majority of the exchange rates tested. With the weekly data, panel unit root tests identify unit root component for the exchange rates and, the unit root tests on a single series basis identify unit root component for 10 foreign exchange markets. However, the variance-ratio tests reject the martingale null for the majority of the exchange rates when using weekly data.

Banking efficiency in transition economies

An increasing share of the banking sector is controlled by foreign capital in the majority of transition countries. To analyse the effects of this trend on the performance of the banking sector in these countries, this study conducts a comparative analysis of the performance of foreign‐owned and domestic‐owned banks operating in the Czech Republic and Poland. We use the stochastic frontier approach to compute cost efficiency scores. Following Mester (1996 ), financial capital is included in the cost frontier model to control for risk preferences. Our finding is that on average foreign‐owned banks are more efficient than domestic‐owned banks. We conclude, however, that this advantage does not result from differences in the scale of operations or the structure of activities.     

技术标准合作:高技术企业集群创新研究的新视角

Shareholder Value Maximisation,Stock Market and New Technology: Should the US Corporate Model be the Universal Standard? 1

In 1992 a blue‐ribbon group of US economists led by Michael Porter concluded that the US stock market‐based corporate model was misallocating resources and jeopardising US competitiveness. The faster growth of US economy since then and the supposed US lead in the spread of information technology has brought new legitimacy to the stock market and the corporate model, which is being hailed as the universal standard. Two main conclusions of the analysis presented here are: (a) there is no warrant for revising the blue‐ribbon group’s conclusion; and (b) even US corporations let alone developing country ones would be better off not having stock market valuation as a corporate goal.     

浅谈企业文化建设的继承与创新

企业文化是企业的无形资产。在企业文化建设过程中,应该重视民族文化的基础作用,借鉴吸收其他民族和企业的优秀文化,有选择地吸收外来的企业文化。企业员工是创建企业文化的主体,要创造各种机会让全体员工参与进来,企业理念要得到员工的理解和认同,转化为员工的日常工作行为。要针对企业发展的具体情况,适时地赋予企业文化新内容,在求新求变中突出个性。
