塔里木油田哈得区块标准井及标准井标准工艺流程的构建

为缩短钻井周期、节约钻井成本,塔北项目部率先提出了以标准井及标准工艺流程为经度,以标准化设计、标准化安全管理、标准化工期及费用、标准化质量控制及考核机制为纬度的"五标"管理理念,而标准井及标准工艺流程为构建"五标"管理理念的关键。根据对哈得区块已完钻的直井、水平井、侧钻井、定向井的统计分析,并结合实际生产开发情况,确定了以直井和水平井作为哈得区块标准井的井型;根据标准井产层的各项地层参数,确定了相应标准井的钻头尺寸组合、钻进深度、套管规格、套管下深、泥浆体系、测井等参数,从而构建了哈得区块直井和水平井2种井型的标准井;同时依据各标准井构建了相应标准井的标准工艺流程。通过塔北项目部的生产实践表明,标准井及标准井的标准工艺流程的构建大大有助于提高油田的经济效益和管理效率。     

知识重叠、知识库特性与创新绩效

以往研究着重探讨重叠/非重叠知识在技术并购中的创新效应，然而在测度知识重叠时仅关注到数量属性而忽略了质量评估。因此，构建一个新的理论框架，利用国家知识产权局2008-2018年专利授权数据，分析217家中国机械制造企业352次国内技术并购案例，探索知识库中重叠、非重叠知识数量和质量属性对并购后创新绩效的影响。结果表明，高质量重叠知识对并购后的企业创新绩效具有正向影响，而高质量非重叠知识则有负向影响。同时，探讨知识数量对并购后创新绩效的影响。研究结果强调了知识重叠对企业获取外部知识的重要性，对企业技术并购实践具有借鉴作用。     

绿色信贷如何影响银行财务绩效——基于地区绿色发展异质性的视角

基于2007~2017年中国34家商业银行非平衡面板数据，实证检验了商业银行开展绿色信贷对其财务绩效的影响，并利用《中国绿色发展指数报告》提供的分省绿色发展指数，考察了绿色发展对绿色信贷与银行财务绩效关系的调节效应。结果表明：商业银行发放绿色信贷投放有助于改善其财务绩效，并且这种改善效应主要来自绿色信贷对银行生息资产收益率的提升作用；绿色发展水平能够增强银行投放绿色信贷的经济效益，并且这种增强效应主要与地方经济增长绿化度和地方政府对绿色发展的支持度有关。商业银行应积极开展绿色信贷业务；政府部门应加强和完善绿色信贷激励政策，以推动绿色金融与绿色经济协同发展。     

Personalized goal-based investing via multi-stage stochastic goal programming

In this paper, we propose a goal-based investment model that is suitable for personalized wealth management. The model only requires a few intuitive inputs such as size of wealth, investment amount, and consumption goals from individual investors. In particular, a priority level can be assigned to each consumption goal and the model provides a holistic solution based on a sequential approach starting with the highest priority. This allows strict prioritization by maximizing the probability of achieving higher priority goals that are not affected by goals with lower priorities. Furthermore, the proposed model is formulated as a linear program that efficiently finds the optimal financial plan. With its simplicity, flexibility, and computational efficiency, the proposed goal-based investment model provides a new framework for automated investment management services.     

Wealth transfer through private placements: Evidence from China

We examine private issuance of public equity (PIPE) in China, and our results suggest that PIPE investors benefit from the price manipulation before and after issuance. These investors tend to cash out after lockup expiration and make large profits. We also find evidence that the trading of PIPE investors after lockup expiration is informed. Tests about the abnormal returns in the 3 years after lockup expiration suggest that at least part of the benefits PIPE investors receive come from wealth transfer from outside investors. Overall, PIPE issuers in China seem to use an opaque mechanism to compensate PIPE investors.     

校企关系与企业R & D投入研究

校企关系被看作是企业与高校交换创新资源的重要纽带,备受国内外学者关注，但其对企业的影响尚未得到一致结论，校企关系是否促进企业技术创新能力提升、降低企业创新投入成本有待进一步研究。以我国2009—2014 年高校上市公司为研究样本，建立回归方程模型，研究了高校和企业间关系对公司R&D投入的影响。实证研究表明，我国高校上市公司中不同属性的校企关系对企业研发投入的影响不同。其中，以高校持股比例为指征的校企关系与公司研发投入呈正相关关系，高校股权可以促进企业研发投入；以高校股东分红比例和高校从业经历高管比例为指征的校企关系与研发投入呈负相关关系，以政府补助为指征的校企关系对高校控股上市公司和非控股上市公司研发投入的影响不同。     

An exploratory study of earnings management detectability,analyst coverage and the impact of IFRS adoption: Evidence from China

Analysts serving as external monitors to managers is a topic of considerable interest in the analyst coverage literature. There are two outcomes of analyst coverage studies: curbing and stimulating earnings management. However, recent studies (such as Yu, 2008) only provide evidence supporting the curbing side. Given the fact that the data of these studies focus on developed markets and the finding of Rodríguez-Pérez and Hemmen (2010) that external governance mechanisms may stimulate earnings management in an opaque information environment, we conjecture whether stimulating side would be dominant in emerging markets. China offers a valuable setting for us to test the question. Using the data of China capital market from 2003 to 2009, we find that analyst coverage stimulates earnings management through above-the-line items (ALIs) where earnings management cannot be easily detected, and curbs earnings management through below-the-line items (BLIs) where earnings management can be easily detected. We also find that the adoption of International Financial Reporting Standards (IFRS) in China does create many new opportunities for managers’ earnings management but does not significantly improve the monitoring effect of analyst coverage. We only find that compared to those without analyst coverage, firms with analyst coverage have a lower level of earnings management through BLIs after IFRS adoption. These findings suggest that information opacity may weaken the monitoring effect of external corporate governance mechanisms and high quality accounting standards in the literal sense may not enhance the monitoring effect of external corporate governance mechanisms if it is not compatible with the market’s institutional environment. In addition, we find that firms with earnings meeting the benchmark have a lower level of earnings management, which indicates that bright-line accounting based rules used in emerging capital markets may constrain the managers’ behavior.

The joint effects of social identity and institutional pressures on audit quality: The case of the Chinese Audit Industry

This article examines how social identity links institutional pressures and audit quality. Combining institutional theory and social identity theory, we theoretically argue that the interaction between social and institutional forces shapes audit quality. Through an analysis of Chinese audit firms from 2000 to 2007, we show that isomorphic imitation has a more significant effect on firms belonging to the same-identity group than firms across cross-identity groups; foreign-affiliated audit firms are more willing to conform to normative pressure from professional networks than local firms; and foreign-affiliated firms are coerced to adapt to the local government’s expectation, particularly when they have a geographically concentrated customer base. We further reveal that a larger customer base attenuates within-identity group imitation but strengthens cross-identity group imitation. The results shed light on the role of social identity in shaping conformity in the audit industry, thus contributing to international convergence–divergence literature and institutional theory.
