基于"GM(1,1)模型"投资LNG项目财务评价研究

近年来,我国液化天然气(LNG)在全年能源使用消耗总量中占有的比值持续上升.由于其具有环境污染小、运输方便等优点,因此,在天然气市场占据了较大的市场份额.同时,由于其显著的经济效益,也受到了投资者的青眯,LNG项目成为能源企业的投资热点.在这种背景下,对LNG项目的动态经营成本进行评价分析,也成为投资者特别关注的方面.本文基于GM(1,1)模型,亦就是灰色系统,对LNG投资项目动态经营成本进行评价研究,为科学地投资LNG项目提供测算依据.     

Weak‐instrument robust inference for two‐sample instrumental variables regression

Instrumental variable (IV) methods for regression are well established. More recently, methods have been developed for statistical inference when the instruments are weakly correlated with the endogenous regressor, so that estimators are biased and no longer asymptotically normally distributed. This paper extends such inference to the case where two separate samples are used to implement instrumental variables estimation. We also relax the restrictive assumptions of homoskedastic error structure and equal moments of exogenous covariates across two samples commonly employed in the two‐sample IV literature for strong IV inference. Monte Carlo experiments show good size properties of the proposed tests regardless of the strength of the instruments. We apply the proposed methods to two seminal empirical studies that adopt the two‐sample IV framework.     

Shareholder Conflict as a Determinant of Corporate Social Responsibility Commitment for Shared Growth

In this study, we seek to explore shareholder conflicts as a determinant of large firms' corporate social responsibility (CSR) commitment for shared growth with subcontractors. Using a sample of 232 firms in the Korean chaebols during 2006'12, we find that CSR commitment is negatively related to controlling shareholders' cash flow rights but positively related to control-ownership disparity. We also find that foreign blockholders mitigate the positive relationship between CSR commitment and control-ownership disparity. This study offers a view of how controlling shareholders and blockholders protect their interests while enhancing their reputations as good citizens through CSR commitment.     

How does face influence the purchase of imitative new products? Moderating roles of product design characteristics

Face plays a profound role in consumption, but the question of how it impacts the purchase of imitative new products remains unanswered in the current literature. Imitative new products, which are legitimate innovations bearing similarities to existing products, are prevalent in many markets. This study investigates how two dimensions of face consciousness—the desire to gain face and the fear of losing face—influence consumers' purchase intentions regarding imitative new products by considering three product design characteristics (new product imitation locus, new product imitation scope, and product hedonism) as boundary conditions. We find through experiments carried out with adult Chinese consumers that the desire to gain face strengthens, but the fear of losing face weakens purchase intention. Moreover, the positive effects of the desire to gain face are weakened by imitation locus (form vs. function imitation) but enhanced by imitation scope (either form or function imitation vs. both form and function imitation); whereas the negative effects of the fear of losing face are strengthened by imitation locus but weakened by imitation scope. Product hedonism enhances the positive effects of the desire to gain face and augments the negative effects of the fear of losing face. This study thus contributes to the face literature by differentiating the roles of two dimensions of face consciousness in affecting consumption of imitative new products. In addition, this study contributes two important constructs—new product imitation locus and new product imitation scope—to the literature on imitative new products.     

从城市社区看社会分层与社会不平等——对天津市两个商品房社区的比较研究

依据对天津市两个居住区进行参与观察和个案访谈所获得的田野材料,通过比较研究的方法,揭示了社区的阶层化现状,勾画出不同社区居民之间的社会分层和不平等状况。并进一步指出,缩小城市区位差异、减少城市中的居住隔离不仅牵涉自然资源和社会资源的公平分配和使用,同时也关乎个体发展的代际公平。
