长庆钻井井控安全应急管理与实践

通过对长庆钻井总公司在长庆油田区域钻井施工中的井控应急管理及应急抢险实践做了全面的分析,通过总结分析,认为井控应急管理工作要紧紧围绕实现"杜绝井喷事故、杜绝人员有毒有害气体中毒"的井控工作目标,要通过不断完善井控应急管理网络和完善井控应急管理制度,树立"积极井控"理念,立足于一次井控,坚持"发现溢流立即关井、疑似溢流关井检查"的关井原则,做到"不发生、控得住、治得了",重视井控应急资源的配备、加强井控应急预案演练和应急抢险的组织是确保井控险情处置安全与成功的保障。

Exploring the effect of diversification strategy on R&D intensity using quantile regression: evidence from France

This study examines the relationship between firm diversification strategy and R&D intensity for a sample of large French companies between 2008 and 2012. Applying quantile regression, we provide evidence that the choice of diversification affects R&D intensity in a differentiated way. The results indicate that a low level of diversification (below the twentieth quantile) has no significant impact on R&D intensity. Conversely, a moderate or high level of diversification has a negative and significant impact on R&D intensity. These findings suggest that R&D intensity seems to be significantly higher in related-business firms than in unrelated-business firms.     

Incentives and teacher effort

Few would contest that teachers are a very important determinant of how much students learn in school, and how to improve teacher performance has been the focus of lively policy debate in both rich and poor countries. This paper examines how teacher incentives, both pecuniary and non‐pecuniary, correlate with teacher effort. Using school survey data from Lao PDR, we estimate measures of teacher effort, including the number of hours that teachers spend preparing for classes and teacher provision of private tutoring outside of class hours, which are not the typical measures used in previous research. Estimation results fit well under the standard labour supply framework and indicate that greater teacher effort is associated with non‐pecuniary incentives such as more teacher autonomy over teaching materials and monitoring as measured by the existence of an active parent – teacher association and the ability of school principals to dismiss teachers. Methodologically, this paper provides a detailed derivation of a simultaneous OLS‐probit model with school random effects that can jointly estimate teacher work hours and tutoring provision.     

不同负债水平公司的资本结构调整速度相同吗?——基于中国上市公司的经验证据

本文利用中国上市公司2003～2010年的数据,采用差分广义矩估计以及连接函数为logit的广义线性模型拟最大似然估计两种方法对资本结构的调整速度与不同资产负债率水平之间的关系进行了探讨。本文的研究结果表明:较高负债率水平的公司有着相对较快的调整速度,并且其公司规模也较大;与此相反,低水平负债率的公司不仅调整速度较慢,而且公司规模较小。同时,本文的研究还发现高负债率的公司对于资本结构的调整主要是通过债务行为来达到的。

东亚货币一体化博弈分析

东亚发展中国家与地区如何选择汇率制度一直是个颇有争议的话题。在“欧元”单一货币区成功实施的背景下,寻求货币一体化便成为东亚各国与地区关注的焦点。实际上,东亚货币一体化就是各参与方根据其参与的成本和收益,权衡利弊得失的决策博弈过程,该过程具有两阶段博弈的特征。     

绿色信贷对产业升级的作用机理与效应分析

绿色信贷通过资金形成、资金导向和资金催化三大机制的作用,促进我国产业结构优化和产业的高级化发展。然而分析表明,绿色信贷实施以来,我国产业升级的实际效应并不显著。主要原因是环境信息不对称、企业环境风险成本不合理以及民众监督缺位等导致绿色信贷的实施效果大打折扣。因此,解决环境保护的激励机制和完善环境风险管理体系,是提升绿色信贷对产业升级作用的关键。
