企业集团控制对上市公司成本粘性的影响研究

选取2011—2019年A股上市公司作为样本，将上市公司纳入企业集团整体框架下，验证企业集团控制对上市公司成本粘性的影响，并对影响机制和影响二者关系的集团内外部因素进行探索。研究结果表明：相比于独立上市公司，企业集团控制尤其非国有企业集团控制能够降低上市公司成本粘性；企业集团通过降低调整成本和缓解代理问题从而降低上市公司成本粘性；企业集团控制的上市公司越多，越有利于降低上市公司的成本粘性；上市公司与集团母公司的业务越相关，越有利于降低成本粘性；在产品竞争程度低的行业和市场化程度低的地区，企业集团控制更有利于降低上市公司成本粘性。     

The role of satisfaction in labor diaspora dynamics: An analysis of BREXIT effects

In diaspora research, people's international mobility is often understood as a response to pull-push forces on an economic macro-level or as part of diasporic waves. However, labor diaspora formations are also influenced by micro-level (i.e., individual perceptions) drivers related to work per se, such as satisfaction. This explorative qualitative study takes a novel angle and focuses on the role of Portuguese nurses’ satisfaction with the evaluation of the Brexit scenario and its effects on this labor diaspora's mobility and stability. The findings illustrate that satisfaction, although affected by uncertainty, mainly relates to perceived working conditions and legislation and the possibilities to communicate with locals and other diasporans. This paper provides suggestions for future research and contributes to the development of theory on staying and human stickiness, explaining the dynamics of exit and entry in (re-)migration decision making.     

The unintended consequence of collateral-based financing: Evidence from corporate cost behavior

This paper examines how real estate appreciation correspondingly changes collateral value, which affects debt structure choices and consequent operating decisions. Specifically, we explore whether collateral-based financing provides a link between real estate values and corporate cost behavior. Our baseline results show that an appreciation of a firm’s real estate assets alleviates its cost stickiness. A further analysis shows that this influence is stronger for firms with less prior bank debt, less dependence on external financing, and a lower leverage ratio. We also observe that the impact of collateral shocks on cost stickiness is more pronounced when selling, general and administrative (SG&A) costs create less future value for mature firms and for firms with weaker external governance. Collectively, our results support the argument that an increase in bank debt arising from collateral value appreciation mitigates agency problems and thus lessens cost stickiness.     

客户粘性的经济后果研究：基于供应商授信视角

供应商授信是企业融资的重要方式之一，本文以2013-2018年A股上市公司为研究样本，深入考察客户稳定性对企业供应商授信的影响及其作用机制，研究结果表明：(1)企业的客户稳定性越强，获得供应商授信的额度越多。该结论在采用工具变量法、倾向得分匹配法和替代变量等一系列稳健性检验之后依然成立。(2) 作用路径识别发现，企业经营业绩、信息环境和审计意见对客户稳定性与供应商授信的关系具有部分中介效应，其中企业经营业绩传递了约12%的客户-供应商的授信效应；信息环境传递了约5%的客户-供应商的授信效应；审计意见传递了约91%的客户-供应商的授信效应。(3)异质性检验发现，当企业所在地信任度较低、法制环境较差时，客户稳定性对企业供应商的授信额度影响更为明显。     

The rise of robots and the fall of cost stickiness: Evidence from Chinese manufacturers

Industrial robots are increasingly used to perform tasks traditionally assigned to humans. Using a sample of Chinese manufacturers, we examine the impact of robot adoption on firm cost stickiness. We find that robot adoption is associated with less sticky costs. The negative impact of robot adoption on cost stickiness is particularly meaningful for state-owned enterprises and firms with higher labour costs, and becomes significantly stronger after the enactment of China's Labour Contract Law, which significantly increases labour adjustment costs. These findings are consistent with the conjecture that the adoption of robots allows firms to reduce their overall labour adjustment costs.     

CEO财务背景丰富度对成本粘性的影响研究

以2012—2021年沪深A股上市公司为研究样本，探讨CEO财务背景丰富度对成本粘性的影响。研究发现，CEO财务背景丰富度对成本粘性有抑制作用，CFO财务执行力在CEO财务背景丰富度对成本粘性的影响关系中具有正向中介作用，环境动态性和环境包容性具有负向调节效应。异质性分析发现，CEO财务背景丰富度对成本粘性的抑制作用在成长期企业中更加显著，但不存在企业规模异质性；CFO财务执行力对中位数以下规模企业和成长期企业的中介作用更加显著；环境动态性和环境包容性对中位数以下规模企业和成长期企业的负向调节效应更加显著。     

电商异质性与线上价格离散

线上价格没有如预期一般走向收敛，反而普遍存在价格离散的情况。文章利用京东、国美、苏宁、天猫经营的六大类家电的价格数据来衡量线上价格离散度，并从电商异质性角度探讨其对于线上市场效率的影响。结果发现：首先，差异化的电商经营模式会通过调价行为、价格黏性以及消费者搜寻活动来加大价格离散程度。其次，电商平台通过其行业占有率以及市场渗透率来提高细分市场的可能性，从而加剧价格离散、降低市场效率。最后，相比平台式电商，自营式电商并没有通过增加调价频次和价格黏性来促进价格离散，反而有可能削弱自营电商的正向加剧效应。文章为线上统一市场的研究提供了新的研究思路，也为政府在电商平台监管和治理方面上提供了有益的借鉴。     

旅游经济地理研究的理论问题：反思与探索

在全球化和互联网高速发展的时代背景下,旅游经济活动的空间格局和行为逻辑发生剧烈的转变。本文从旅游经济活动的地理属性出发,对旅游经济活动的地理研究进行回顾,重点评述了国际旅游地理学界所做的多次探索,并对核心问题的理论依据与逻辑进行阐述。研究发现：当前研究尚未明晰旅游活动的基本地理逻辑,理论框架较为模糊,且过度依赖新经济地理中的演化理论,研究边界和研究问题尚未清晰。基于此,本文以经典的旅游系统论为理论框架,提出旅游经济地理现象研究的3个关键理论问题：（1）旅游空间粘性影响下的旅游市场空间生产机制;（2）流动范式的地理逻辑带来的新型人地互动关系;（3）弱关系空间组织下的旅游目的地经济发展一般机制。本研究所做的尝试,有助于提升旅游地理理论的解释力和适用性,也有助于推动主流经济地理学对旅游话题的关注。     

Empirical analysis of the relationship between labour cost stickiness and labour reforms in Spain

This study performs an empirical analysis on the relationship between labour cost stickiness and the decrease in employment protection in the Spanish labour reforms in 2010 and 2012. Following these reforms, the sticky behaviour of labour costs substantially decreased with respect to the pre-reform period. All constituents of total labour costs followed a similar pattern: wages, social security contributions and number of employees. Results are robust to different models, estimation methods, periods of time, and industries, as well as with respect to endogeneity concerns.
