Purpose Governments worldwide have used administrative reforms to align public organizations with the needs of their key stakeholders. However, despite successfully implementing them, they do not consistently achieve the desired organizational performance. This paper aims to explore the relationship between the implementation of administrative reforms and the performance of public organizations from a comprehensive perspective. For this purpose, the authors analyze the mediation role of three crucial dynamic capabilities. Design/methodology/approach This research used a survey-based methodology. Structural equation modeling (SEM) was used to analyze the data obtained from a sample of public officials and managers working in public organizations in the State of Ceará (Brazil). Findings The results of this study suggest that dynamic capabilities can have a decisive role in implementing government policy proposals and helping public organizations align their outcomes with stakeholders' needs. In addition, they indicate the existence of two levels of capabilities and identify a road map for their implementation. Practical implications From a practical point of view, by identifying these capabilities and their interrelationship, this study provides a roadmap to reduce the complexity of their use and help managers of public organizations deliver desired outcomes relating to the quality of individual and collective stakeholders. Originality/value This study makes important contributions to the literature, enabling scholars and practitioners to see the result of government policy proposals beyond the efficient use of public resources. It shows the role of dynamic capabilities as mediation instruments for changing public organizations, which can be used in administrative reform implementations and continuous improvement processes. Finally, it provides empirical research on the interaction between the three dynamic capabilities in the context of public organizations, differentiating these capabilities into two levels, which provides a road map for their implementation and development by public managers.
世界各国政府利用行政改革使公共组织与其主要利益攸关方的需求保持一致。然而,尽管成功地实施了它们,它们并没有始终如一地达到预期的组织绩效。本文旨在从综合的角度探讨行政改革的实施与公共组织绩效之间的关系。为此,作者分析了三个关键动态能力的中介作用。设计/方法/方法本研究采用了基于调查的方法。结构方程模型(SEM)用于分析从巴西塞埃尔州公共组织的公职人员和管理人员样本中获得的数据。研究结果表明,动态能力在实施政府政策建议和帮助公共组织将其结果与利益相关者的需求相一致方面具有决定性作用。此外,它们指出存在两种级别的能力,并确定其实现的路线图。从实践的角度来看,通过识别这些能力及其相互关系,本研究提供了一个路线图,以减少其使用的复杂性,并帮助公共组织的管理者提供与个人和集体利益相关者的质量相关的预期结果。本研究对文献做出了重要贡献,使学者和实践者看到政府政策建议的结果超越了公共资源的有效利用。它显示了动态能力作为变革公共组织的调解工具的作用,可以在行政改革实施和持续改进过程中使用。最后,对公共组织背景下三种动态能力之间的相互作用进行了实证研究,将这些能力划分为两个层次,为公共管理者实施和发展这些能力提供了路线图。

Purpose Adoption and implementation of sustainable strategies (SS) in firms have been widely studied; however, there is scarce evidence of factors that affect the overall firm performance (FP). Therefore, in this research the variables knowledge management (KM) and professionalization (PR) toward the adoption of SS and their impact on FP are promoted. Design/methodology/approach Data from 120 firms in manufacturing industry in Coahuila, Mexico, were collected, and the study is based on the PLS-SEM technique. Findings The results revealed that (1) KM and PR present a positive impact on SS and (2) SS are positively related to FP. Practical implications For manufacturing managers, it is necessary to implement SS that meet the expectations of stakeholders, in addition to training human resources with the ability to achieve the aims of the firm and at the same time take care of the environment. As for corporate policymakers, it is essential that they promote global environmental care strategies based on collaborative business. Originality/value This research contributes to literature on business management, mainly to the incorporation of SS that allow boosting the economic aspect, but without neglecting social and environmental part.
企业可持续战略的采用和实施已经得到了广泛的研究;然而,很少有证据表明影响企业整体绩效(FP)的因素。因此,本研究探讨了知识管理(KM)和专业化(PR)这两个变量对企业战略支持的影响及其对企业战略支持的影响。设计/方法/方法收集了墨西哥科阿韦拉120家制造业公司的数据,并基于PLS-SEM技术进行了研究。结果表明:(1)KM和PR对SS有正向影响,(2)SS与FP有正相关。对于制造经理来说,除了培训人力资源,使其能够实现公司的目标,同时照顾好环境之外,有必要实施符合利益相关者期望的SS。对于企业决策者来说,推动基于合作商业的全球环境保护战略至关重要。独创性/价值本研究对企业管理的文献有贡献,主要是纳入了SS,可以促进经济方面,但不忽视社会和环境部分。

Purpose This paper aims to analyze the economic-financial performance (EFP) and value creation (VC) in the Brazilian construction industry. Design/methodology/approach Based on the theories of strategy and finance, a quantitative-qualitative, descriptive and explanatory and applied study was carried out, contrasting the performance of the Direcional company and the civil construction industry – both listed on the Brazilian Stock Exchange and the Over-the-Counter Market (B3) Findings The analysis of the EFP in the Brazilian construction industry shows that EZTEC, Helbor, Trisul and Direcional were the companies with the best EFP in the period. The analysis of the Economic Value Added (EVA®, henceforth EVA), as a VC metric and basis for assessing the relative technical efficiency score by Data Envelopment Analysis (DEA®, henceforth DEA), revealed that the companies Direcional, EZTEC, MRV and CR2 were considered efficient throughout the period covered. The multicriteria methodology for empirical testing of the EFP and VC allowed not only contrasts Direcional's results with the other companies of the construction industry but also offered a complementary tool for comparative analysis of enterprises of different sizes, structures and realities. Research limitations/implications Regardless of any contextual limitations, from a theoretical point of view, the research not only helps fill the research gap aforementioned but also expands knowledge on the topic and demonstrates how this multi-criteria methodology (integrating DEA and EVA) can be used to assess EFP and VC in addition to traditional tools. However, this new approach evaluates, at the same time, corporate and sectorial effectiveness by contrasting the efficiency and efficacy (simultaneously) in the generation of performance and value of a company in relation to the industry. Practical implications Significant implications for managerial practice could be noted by offering a tool to improve company performance and creating a competitive benchmarking process for analysts, investors, managers, financing agencies, shareholders, policymakers and business owners, as well as organizations and sectors in similar situations – who need to assess the EFP and VC holistically and improve their decision-making processes. Originality/value The uniqueness and innovation of this research come from the original multi-criteria methodology developed, applied and validated for analysis of EFP and VC. This methodology was operationalized through DEA applied to the companies' EVA, making it possible to compare corporate results and those of the whole industry in a balanced way – an unexplored issue in the literature, especially in emerging economies, opening several avenues for future research.
本文旨在分析巴西建筑业的经济财务绩效(EFP)和价值创造(VC)。基于战略和金融理论,进行了定量定性,描述性和解释性和应用研究,对比了该公司和民用建筑行业的表现-都在巴西证券交易所和场外交易市场(B3)上市。Trisul和dional是该时期EFP最好的公司。通过数据包络分析(DEA)对经济增加值(EVA®,以下简称EVA)作为风险投资指标和评估相对技术效率得分的基础进行分析,发现在整个覆盖期间,公司dional, EZTEC, MRV和CR2被认为是高效的。对EFP和VC进行实证测试的多标准方法不仅可以将dional的结果与建筑行业的其他公司进行对比,而且还为不同规模、结构和现实的企业提供了比较分析的补充工具。无论任何背景限制,从理论角度来看,该研究不仅有助于填补上述研究空白,而且还扩展了该主题的知识,并展示了除了传统工具之外,如何使用这种多标准方法(整合DEA和EVA)来评估EFP和VC。然而,这种新方法同时通过对比公司在与行业相关的业绩和价值产生方面的效率和功效来评估公司和行业的有效性。通过提供一种工具来提高公司绩效,并为分析师、投资者、经理、融资机构、股东、政策制定者和企业主以及处于类似情况的组织和部门创建一个有竞争力的基准流程,可以注意到对管理实践的重大影响——他们需要全面评估EFP和VC,并改进他们的决策流程。原创性/价值本研究的独特性和创新性来自于原始的多标准方法,该方法开发、应用并验证了EFP和VC的分析。该方法通过将DEA应用于公司的EVA来实施,从而可以以平衡的方式比较公司结果和整个行业的结果-这是文献中未探索的问题,特别是在新兴经济体中,为未来的研究开辟了几种途径。

Purpose Third-party certifications promote firms' high standards and enhance their legitimacy and reputation, potentially positively impacting their performance, namely on exports. Design/methodology/approach This paper studies the differences in firms' export performance between firms with and without the “SME Leader” label, a Portuguese firm-specific label. This study data set comprises data for 5.489 SMEs, for 2014–2020, where 2.950 firms obtained their certification during the period and 2.539 are non-certified control firms. The methodology adopted circumvents the traditional endogeneity problems in this type of study. Findings The results indicate that the “SME Leader” label does not directly improves a firm's export performance. Additionally, industry characteristics seem relevant for the relationship between SMEs' certification and their levels of internationalization. Originality/value Since the study sample includes firms from all industrial sectors, this study results apply to various organizations.
第三方认证促进了公司的高标准,提高了他们的合法性和声誉,对他们的表现,即出口产生了潜在的积极影响。本文研究了拥有和没有“中小企业领袖”标签的企业之间出口绩效的差异,这是葡萄牙企业特有的标签。本研究数据集包括2014-2020年5489家中小企业的数据,其中2950家企业在此期间获得了认证,2539家为未认证的控制企业。采用的方法规避了这类研究中传统的内生性问题。结果表明,“中小企业领袖”标签并不能直接提高企业的出口绩效。此外,行业特征似乎与中小企业认证与其国际化水平之间的关系有关。由于研究样本包括来自所有工业部门的公司,因此本研究结果适用于各种组织。

Purpose The purpose of this research paper is to establish the impact of process and service innovation on non-financial and financial performance in the tourism sector, as well as to explain the mediating role of organizational learning. Design/methodology/approach A quantitative approach was used, based on partial least squares–structural equation modeling (PLS-SEM), Smart PLS 4.0 software. The sample consisted of 426 establishments in the tourism sector in Zone I, Ecuador. Online surveys were employed to collect data, yielding 118 responses, to assess the impact of innovation on business performance from 2020 to 2022. Findings Process and service innovation positively and significantly affect non-financial and financial performance, respectively. Organizational learning mediates the relationship between process innovation and disservice. The relationship between non-financial and financial performance could not be confirmed. The model explains 53.10% of non-financial performance and 26.10% of financial performance. Originality/value The relationship between innovation and performance in the tourism sector has been studied in several developed economies, while little has been studied in developing countries. This work contributes to an empirical discussion including a mediating variable in the innovation–performance relationship in the Latin American context.
本研究的目的是建立流程创新和服务创新对旅游行业非财务绩效和财务绩效的影响,并解释组织学习的中介作用。设计/方法/方法采用定量方法,基于偏最小二乘-结构方程建模(PLS- sem), Smart PLS 4.0软件。样本包括厄瓜多尔第一区旅游部门的426家机构。通过在线调查收集数据,获得118份回复,评估2020年至2022年创新对企业绩效的影响。发现流程创新和服务创新对企业非财务绩效和财务绩效分别有显著的正向影响。组织学习在过程创新和损害服务之间起中介作用。非财务绩效和财务绩效之间的关系无法证实。该模型解释了53.10%的非财务绩效和26.10%的财务绩效。一些发达经济体研究了旅游部门创新与绩效之间的关系,而发展中国家的研究却很少。这项工作有助于实证讨论,包括拉丁美洲背景下创新绩效关系中的中介变量。

Purpose In the current study, corporate investment is examined by using a user cost of capital model for two important Latin American economies: Brazil and Mexico. In this paper, a dynamic user cost of capital model is employed. The extended model also accounts the investment model with the convex adjustment cost. Moreover, the link between structural change, financial liberalization and investment is also investigated. The present study, therefore, sheds new lights on the investment behavior of the Latin American emerging markets. Design/methodology/approach The differenced generalized method of moments approach is employed to control the endogeneity, heteroscedasticity and autocorrelation for modeling the corporate investment over 20 years for both countries. Findings The findings indicate that the dynamic user cost of capital-based investment model explains the corporate investment in Brazil and Mexico. Especially, the interest rate and depreciation explain the investment behavior of nonfinancial firms in both countries. At the same time, structural change and financial liberalization do not have a significant impact on interest rates, an important user cost of capital. Originality/value This is the first study examines the corporate investment using dynamic user costs of capital approach for an emerging market. The user cost of capital-based investment models is clearly understudied models for emerging markets. This study is particularly important for emerging markets as investment models need to have a theoretical background.
在目前的研究中,公司投资是通过使用两个重要的拉丁美洲经济体的用户资本成本模型来检验的:巴西和墨西哥。本文采用了一个动态用户资本成本模型。扩展模型还考虑了带有凸调整成本的投资模型。此外,还研究了结构变化、金融自由化和投资之间的联系。因此,本研究为拉丁美洲新兴市场的投资行为提供了新的视角。设计/方法/方法采用差分广义矩量法控制两国20多年企业投资的内生性、异方差和自相关性。研究结果表明,巴西和墨西哥的企业投资以资本为基础的动态用户成本模型解释。特别是,利率和贬值解释了两国非金融企业的投资行为。与此同时,结构性变化和金融自由化对利率这一重要的资金使用成本没有显著影响。原创性/价值这是第一个使用动态用户资本成本方法研究新兴市场企业投资的研究。对于新兴市场来说,基于资本的投资模式的用户成本显然没有得到充分的研究。这项研究对新兴市场尤为重要,因为投资模型需要有理论背景。

Purpose This study aims to examine the effect of corporate governance mechanisms on social responsibility in Latin America. Design/methodology/approach The hypotheses were tested using a sample of 371 companies based in eight Latin American countries, resulting in 4,823 observations. Findings The results show that more independent boards, with greater female representation and the presence of a sustainability committee lead companies to behave more ethically. The findings indicate that corporate governance mechanisms play an important role for companies to engage in social responsibility actions. Practical implications Governments can use these findings to draft regulations that encourage Latin American companies to disclose more non-financial information and to support a more diverse board composition. The evidence shows that the quality of national governance plays a key role in times of crisis by encouraging more responsible behavior by companies. Originality/value This study broadens the scope of application of agency theory and the resource-based view by demonstrating that the board of directors is a unique composition and that organizations must understand how to balance external and internal members on their boards in order to achieve higher social and environmental performance.
本研究旨在探讨拉丁美洲公司治理机制对社会责任的影响。设计/方法/方法使用八个拉丁美洲国家的371家公司的样本对假设进行了测试,产生了4,823个观察结果。研究结果表明,董事会越独立,女性代表越多,可持续发展委员会的存在会使公司的行为更合乎道德。研究结果表明,公司治理机制对公司参与社会责任行动起着重要作用。实际影响各国政府可以利用这些调查结果起草规章,鼓励拉丁美洲公司披露更多的非财务信息,并支持董事会组成更加多样化。有证据表明,在危机时期,国家治理的质量通过鼓励企业采取更负责任的行为发挥着关键作用。本研究通过证明董事会是一个独特的组成,以及组织必须了解如何平衡董事会的外部和内部成员,以实现更高的社会和环境绩效,拓宽了代理理论和资源基础观点的应用范围。

Purpose To empirically study the determinant factors of adopting work–life balance measures at the firm level. Design/methodology/approach After reviewing the main theories that explain work–life balance practices, IBEX-35 Spanish companies during 2015–2019 are studied to see whether the firm sector, the presence of female employees, qualified personnel, a company agreement and an equality plan determine these types of practices. Findings The results indicate a negative relationship between the firm activity sector and adopting work–life balance practices. Industrial companies offer fewer work–life balance measures than service companies. A company agreement implies more extensive adoption of work-life practices. Older companies are characterized by greater adoption of work-life practices, in contrast to their level of profitability that is associated negatively with these practices. Practical implications Since it is difficult for industrial companies to change their idiosyncrasies, it is necessary to incorporate other measures that promote work–life balance, such as timetable flexibility. Companies and policymakers should promote the advantages of a company agreement to contribute to the implementation of work–life balance practices. Originality/value The empirical evidence is scarce, especially in Spain and at the company level, given that most previous studies have focused on workers and the Anglo-Saxon sphere. Given the growing interest in this topic in the business world, the authors intend to contribute to this scarce literature by incorporating variables considered in previous studies, as well as other more innovative ones (agreement, equality plan) in a single model through a longitudinal study.
目的从企业层面实证研究工作与生活平衡措施的决定因素。在回顾了解释工作与生活平衡实践的主要理论之后,研究了2015-2019年期间IBEX-35西班牙公司,以了解公司部门,女性员工,合格人员,公司协议和平等计划是否决定了这些类型的实践。研究结果表明,企业活动部门与采用工作与生活平衡实践之间存在负相关关系。与服务公司相比,工业公司提供的工作与生活平衡措施较少。公司协议意味着更广泛地采用工作与生活的做法。老公司的特点是更多地采用工作-生活实践,相反,他们的盈利水平与这些实践负相关。由于工业公司很难改变他们的特质,因此有必要采取其他措施来促进工作与生活的平衡,例如灵活的时间表。公司和政策制定者应该宣传公司协议的优势,以促进工作与生活平衡实践的实施。鉴于之前的大多数研究都集中在工人和盎格鲁-撒克逊领域,经验证据很少,尤其是在西班牙和公司层面。鉴于商业世界对这一主题的兴趣日益浓厚,作者打算通过纵向研究将以前研究中考虑的变量以及其他更具创新性的变量(协议,平等计划)纳入单一模型,从而为这一稀缺文献做出贡献。

Purpose The aim of this paper is to provide an overview of the impact of the implementation of Colombian Corporate Insolvency Act 1116 of 2006 in the period 2008–2018 and to assess the relevance of a broad set of financial predictors, as well as variables related to the economic context or the characteristics of the process itself, in explaining the failure of reorganization processes. Design/methodology/approach Both logit and probit models are estimated, starting from a large number of variables proposed in the literature which are then narrowed down to a final selection based on their individual significance and machine learning. Findings The results show the prevalence of a limited number of financial variables related to equity, indebtedness, profits and liquidity as predictors of the failure of reorganization processes. The use of financial information from the year prior to the completion of the reorganization improves predictive accuracy and reliability. The debt-to-equity indicator provides no significant explanatory power, while voluntary entry into a reorganization process favors its success. Originality/value While financial and accounting information is used across the literature to predict insolvency events, it is used here to predict success or failure in reorganization processes under the conditions imposed by a specific legislative act in a Latin American context.
本文的目的是概述2008-2018年期间实施《哥伦比亚公司破产法1116》的影响,并评估一系列广泛的财务预测因素以及与经济背景或流程本身特征相关的变量在解释重组流程失败方面的相关性。设计/方法/方法从文献中提出的大量变量开始估计logit和probit模型,然后根据它们的个体重要性和机器学习将其缩小到最终选择。研究结果表明,与股权、负债、利润和流动性相关的有限数量的财务变量普遍作为重组过程失败的预测因素。使用重组完成前一年的财务信息提高了预测的准确性和可靠性。债务权益比率指标没有提供显著的解释力,而自愿进入重组过程有利于其成功。原创性/价值虽然财务和会计信息在整个文献中用于预测破产事件,但在拉丁美洲背景下,在特定立法行为施加的条件下,它被用于预测重组过程的成功或失败。

PurposeThis paper analyses how contextual factors at universities (entrepreneurship education and program learning) and cognitive variables (perceived behavioral control, implementation intentions, and attitude) influence entrepreneurial intentions among Latin American university students.Design/Methodology/ApproachThe empirical analysis employs a multilevel (hierarchical) linear model with a sample size of 9012 university students taken in 2018 from nine Latin American countries: Argentina, Brazil, Chile, Colombia, Costa Rica, Ecuador, México, Panamá, and Uruguay.FindingsOverall, the university context and cognitive variables contribute to explaining entrepreneurial intentions in university students. Whereas program learning constitutes a variable that directly and indirectly explains entrepreneurial intentions among university students, attending entrepreneurship courses negatively influences their entrepreneurial intentions.Originality/valueA central premise of this study is that the entrepreneurial process in university students is a multilevel phenomenon, given that university context and cognitive variables are key factors in entrepreneurial intentions. The findings support this premise and contribute to the existing literature on entrepreneurship in emerging economies. Nevertheless, the results reveal a more nuanced picture regarding the role of university context on the entrepreneurial intentions of students.
目的分析大学情境因素(创业教育和项目学习)和认知变量(感知行为控制、实施意向和态度)对拉美大学生创业意向的影响。设计/方法/方法实证分析采用多层次(分层)线性模型,样本量为2018年来自9个拉丁美洲国家的9012名大学生:阿根廷、巴西、智利、哥伦比亚、哥斯达黎加、厄瓜多尔、莫桑比克、巴拿马和乌拉圭。总体而言,大学环境和认知变量有助于解释大学生的创业意向。而项目学习构成了直接和间接解释大学生创业意图的变量,参加创业课程对大学生创业意图有负向影响。本研究的中心前提是,大学生的创业过程是一个多层次的现象,因为大学环境和认知变量是影响创业意向的关键因素。研究结果支持了这一前提,并对现有的新兴经济体创业文献做出了贡献。然而,研究结果揭示了大学环境对学生创业意向的影响。
