大学新生党员先进性教育及发挥先锋模范作用的研究

随着高中阶段发展党员工作的加强,大学新生中的党员数量逐年增加,已经成为大学生党员的重要来源。但是,这部分新生党员的先进性水平和先锋模范作用的发挥尚存在许多问题。因此,本文从大学新生党员先进性体现和先锋模范作用发挥的要求及存在的主要差距分析入手,提出了加强大学新生党员先进性教育,充分发挥先锋模范作用的对策和建议。     

An equilibrium displacement approach to oligopoly market analysis: an application to trade in the Korean infant formula market

This article uses an equilibrium displacement model (EDM) to assess the impact of a change in trade policy in the Korean infant formula market that is assumed to be oligopolistic. Domestic oligopolists compete in a market for a homogenous good with importing firms who enjoy the same level of market power as the domestic producers. Within an EDM framework, we investigate how the market adjusts to a new equilibrium in response to an external policy shock that improves access to foreign goods. Our empirical work consists of two steps. We first econometrically estimate the market demand elasticity and market power parameter. Then, using these estimates, we simulate our EDM model to assess the distributional effects of tariff cuts and other changes in marginal cost. Simulation results show that, with a lower market price and increased consumption, the change in consumer surplus resulting from tariff reduction is unambiguously positive, but that the change in social welfare can be in either direction, depending on who receives market rents associated with imports. When importing firms are domestic, the domestic welfare change is definitely positive. However, in the case of foreign importing firms, the direction of the welfare change crucially depends on the demand elasticity.     

家族控制中的亲缘效应分析与检验

本文以家族企业的全部家族成员为分析对象,探讨了不同亲缘关系的效应,得出以下结论:由单一家族成员控制家族企业的乏亲缘关系不利于企业的发展;核心家庭对企业绩效的改进起到显著促进作用,但这种作用主要体现在股权控制中,在家族管理权控制和金字塔控制中此效应并不明显;近亲关系对企业绩效的提升起到一定的阻碍作用,尤其是在管理权控制机制中其效应更加明显;远亲关系的作用方向不太稳健,在股权控制中起到显著的积极作用,但在管理权控制和金字塔中控制中则具有一定的消极作用;不同控制机制下的亲缘关系对企业绩效的边际贡献存在差异,即不同的家族控制模式应相机地选择不同的亲缘关系组合以改善企业的治理效率。     

Exit and transition: Exploring the survival status of Airbnb listings in a time of professionalization

This study analyzes the survival status of shared and non-shared listings in the peer-to-peer accommodation market. Using a large data set from Airbnb in Beijing, we identify 8640 shared listings and 50,741 non-shared listings. We then investigate the exit event and the identity transition event for both types of listings by applying a discrete-time hazard model. Our results suggest that, for the exit event, the two types of listings show significant differences in terms of survival determinants, including response time, tourism specialization, market volume, professionalization, and Covid-19. For the identity transition event, we find that internal flow exists in the market, mainly from shared listings to non-shared listings, and this flow is influenced by certain factors (i.e., capacity, facility, rating, reviews, minimum stay, service quality, tourism specialization, market volume, platform professionalization, and Covid-19).

Affective commitment within the public sector: antecedents and performance outcomes between ownership types

How to generate affective commitment and realize its performance potential is deemed critical to public management. But in the context of service outsourcing, does ownership type influence its antecedents and performance outcomes? Drawing on postal survey data for English leisure providers, we find training is an antecedent across public and private ownership types; performance appraisal is an antecedent for private ownership only; while performance-related pay carries an insignificant effect. Affective commitment holds business and customer performance outcomes for public ownership, but insignificant effects are observed for external ownership types. Implications of this contextual variation for public management theory are discussed.     

The Moderating Role of Country of Origin on Brand Equity,Repeat Purchase Intentions,and Word of Mouth in Trinidad and Tobago

Brand equity has emerged as a critical aspect of marketing, but its effect on consumer behavioral intentions from a developing country perspective has not been sufficiently examined. This study proposes that country of origin and product type will moderate the relationships between brand equity, consumer repeat purchase intentions, and word of mouth. Data were collected from 157 customers and analyzed with regression analysis. Our results confirm the moderating role of COO such that favorable COO weakens the impact of brand equity on consumers' behavioral intentions. Product type was not significant. Theoretical and practical implications of these findings are presented as well as the limitations, and future research opportunities are discussed.     

CEO succession and firms’ internationalization processes: Insights from German companies

This article analyses the relationship between CEO succession events and German firms’ internationalization processes, which is represented by the degree of internationalization (DOI) growth and internationalization rhythm. Based on a theoretical framework combining elements of agency theory, institutionalism and upper echelons approach, we propose a longitudinal model to examine the relationships of both process variables with the number of CEO changes and succession type (internal vs. external succession), respectively. The results of our study of 102 German firms over 23 years (1990–2012) show an inverted U-shaped impact (no impact) of the number of CEO changes (succession type) on the DOI growth and a positive (negative) monotonic effect on the rhythm of internationalization.     

Foreign direct investment productivity premium and foreign affiliates' heterogeneity: A comparison between advanced and emerging market overseas investments in the EU

This paper aims to investigate the existence of productivity heterogeneity among foreign‐owned firms (FOFs) based in the European Union (EU). Using firm‐level data for a sample of FOFs investing in the EU over the period 2006–14, we find that foreign affiliates from advanced countries (AFOFs) show a positive productivity gap compared to foreign affiliates from emerging countries (EFOFs). However, when we consider the type and the motivation of foreign direct investment, our results reveal that, while AFOFs always seem to be more productive than EFOFs in manufacturing sectors, EFOFs appear to enjoy a productivity premium compared to AFOFs in the services, when their activity occurs in the same industry as their parent and they operate in less knowledge‐intensive market sectors.
