This research aims to study the impact that the interaction between internal R&D and R&D cooperation has on the technical efficiency of firms, as well as to analyse whether firms belonging to a group achieve any additional level of technical efficiency.

We employ the stochastic frontier version of a knowledge production function, particularly the inefficiency model, and we combine the stochastic frontier analysis (SFA) and the complementarity approach.

The interaction between internal R&D and R&D cooperation has a positive and significant impact on technical efficiency when the complementarity test is applied between companies belonging to a group, and there is no interaction when they do not belong to a group.

Knowing this type of information in advance is critical for managers and policymakers, as it allows them to avoid undesirable combinations of innovation strategies or contexts not favourable for their implementation, as well as the formulation of policies leading to an efficient allocation of public resources.

To the best of the authors’ knowledge, this paper contributes an original approach in evaluating the complementarity of internal R&D and R&D cooperation from the perspective of technical efficiency and group membership, combining the SFA and the complementarity approach.

本研究擬探討內部研發與研發合作之間的相互作用會如何影響公司的技術效率;研究亦擬分析屬於集團的公司會否達致更高一級的技術效率。

研究人員採用一個知識生產函數的隨機前沿方法,尤其是低效模型,研究人員並且把隨機前沿分析和互補法結合起來進行探討。

預先了解這方面的資料和信息對管理人員和政策制定者至關重要,這是因為這可讓他們避開不良的創新策略組合,以及那些不利於推行創新策略的環境;而且,能否制定可為公共資源高效分配的政策,也有賴於了解這方面的信息和資料。

據我們所知,本研究從技術效率和組成員身份的角度去評定內部研發與研發合作的互補性,在這方面提供了新穎的研究方法;而且,本研究結合了隨機前沿分析和互補法,這也是創新的做法。

The purpose of this paper is to analyze drivers for the proactive disclosure of information via the web in Colombian non-governmental organizations (NGOs) as a strategy for fostering their legitimacy and responding to the institutional pressure to which they are subjected.

The web sites of 196 NGOs from Colombia have been analyzed, first, via an Online Transparency Index that is consistent with Cronbach α coefficient and later, by performing a Tobit regression analysis.

The proactive online disclosure of information in Colombian NGOs is very low. In spite of the high distrust of the resource management they receive, the financial information is the least aspect disclosed in their web pages. In addition, the larger NGOs are the entities that most disclose information via their web site. Likewise, the factors of “internationalization”, “donations”, “community services” and “dependence on voluntary work” show a positive effect on certain aspects of the online disclosure of information analyzed.

The lack of web use as a strategy for a proactive disclosure of information is clearly observed. Therefore, both obligatory and voluntary accountability mechanisms should be more aware of the need for fostering the benefits of a web site, as being transparent in a proactive manner will increase trust in this sector.

As the majority of the research papers related to online disclosure are focused on the corporate and public sector, this study addresses the issue of the NGO sector and particularly aims to contribute to the scarce literature regarding web use of entities from developing countries.

In view of the increased impact of social media, non-profit organizations (NPOs) should review their management model for stakeholder relationships. The purpose of this paper is to analyze the influence of factors on the use of Twitter by NPOs as a mechanism for disclosing information and dialogue with their stakeholders, and in particular: “donor dependence,” “fundraising expenses,” “organizational age,” “organizational size,” “online community size,” “network activity” and “board size.”

A content analysis of Twitter use as a strategic communication tool was conducted and a multivariable linear regression analysis was performed.

Smaller organizations and those with a larger online community are the most interested in implementing Twitter as a one or two-way communication strategy. Likewise, the NPOs with the highest degree of donor dependence strive most in the use of contents of Twitter as one-way communication mechanism.

This study contributes to a better understanding of social media implementation in the NPO sector and advances the identification of the main causes that motivate NPOs to improve their accountability through social media.

The paper’s subject is relatively innovative due to the scarce studies focussing on social media used by NPOs. In spite of the advantages offered by Twitter, few studies have specifically addressed NPOs’ current use of this platform, and fewer still have analyzed the factors that motivate them to use this tool.

This paper aims to investigate the extent of intellectual capital disclosure (ICD) through websites and social media in Spanish local government (SLG) and analyze the factors that explain their disclosure.

The study applies content analysis and regression techniques. The ICD is analyzed for Spanish municipalities with more than 100,000 inhabitants and provincial capitals over a period from January 2018 to February 2020.

Findings emphasize that the quantity of disclosed information on intellectual capital (IC) is in the low level, particularly with regard to human capital (HC). Furthermore, the results show that the information provided via social media mainly concerns the relational capital (RC). On the other hand, results obtained indicate that larger municipalities, with lower financial autonomy and whose citizens have a high income level use the online media (both websites and social media) more actively to disclose information about IC. Finally, municipalities led by women and with high level of citizens' education exert a positive influence in the ICD only on websites.

This paper makes a number of key contributions to the existing body of knowledge, focusing on ICD, a neglected area in the public sector accounting literature. It explores and identifies the supply-side and demand-side determinants of information affecting the ICD in local governments. The results of this research could be useful for policymakers, regulators and governments' managers to improve the online information addressing ICD issues.

This paper adopts an innovative perspective by investigating the use of alternative tools for ICD in local government context (websites and social media). To the best of the authors’ knowledge, this is the first study that focuses on investigating the determinants of online ICD in local governments.

Increasingly, universities are adopting social media as a strategy to improve their competitive advantage. However, little is known of whether or not stakeholders are actually engaging with universities in such online environments. The purpose of this paper is, first, to analyze the level of stakeholders’ engagement via social media, particularly Facebook, in European and US universities. Second, to examine the influencing factors that boost online interactions, in particular, “location,” “transparency,” “size,” “academic performance” and “activity.”

An engagement index and a multivariate regression analysis were carried out. Regarding the sample, European and US universities belonging to the “Top 100” of the Academic Ranking of World Universities were analyzed.

Despite the large online community that US universities possess, European universities attain the higher level of online engagement from its stakeholders. In particular, the greatest level of engagement is achieved by European universities of greater size, in terms of students, with lower academic performance and a lower level of online activity.

This study contributes to existing literature by identifying the actual social impact of social media to build successful relationships with the stakeholders of higher education entities.

This paper can contribute to the current scarcity of literature concerning social media to improve new models of accountability in higher education entities with different managerial models.

Achieving good sustainability performance requires balancing higher economic profits with better environmental and social performance. Knowledge plays a key role in improving corporate sustainability performance, but this knowledge is becoming increasingly complex, specific and dispersed among many scientific, technological and business actors. Science and technology parks (STPs) are infrastructures designed to host varying types of organizations that can bring together new, disruptive knowledge. Our purpose is to unveil how these spaces can be drivers of sustainability performance for companies.

We test our hypotheses on a longitudinal database of Spanish companies over the period 2009–2016 using structural equation models (SEMs).

This research confirms that a firm’s location in an STP helps improve its sustainability performance, provided that conditions are optimal in the STP. These optimal conditions are based on an abundance of knowledge spillovers available to the firm and the firm’s ability to harness them, especially those of a more disruptive nature, through absorptive capacity.

Results of this study yield implications for academia in the form of future lines of research and practical implications for policymakers and managers of both STPs and the organizations that host them.

The purpose of this paper is to analyse the internal and external factors related to the disclosure of environmental information in universities which reflect the actions carried out in these universities.

Taking as reference the first 200 universities in the Shanghai ranking, several factors associated with the degree of environmental information disclosure in universities – governance dimension, the relationship and participation of stakeholders, position and prestige as signs of the quality of the institution and cultural concern in the university’s country for the environment – are analysed.

The results obtained show that the size of the leadership team, stakeholder participation, the position of the university in rankings and cultural concern in the university’s country for the environment are determining factors in the university’s environmental actions and, consequently, in their disclosure. Other factors – such as the size of the university, the level of self-financing and financial autonomy – do not affect the disclosure of environmental information.

Scant research exists on the environmental commitments of universities; this paper aims to fill that gap. Their role as the main channel of research and as instructors of future professionals makes them points of reference in society. Research on university ranking has traditionally focussed on teaching and research results, but environmental issues are becoming increasingly important. This paper enumerates the factors that influence the dissemination of environmental information in the most prestigious universities. This research also provides an original approach by considering not only top-down but also bottom-up strategies through communication channels and the incidence of cultural factors.

The purpose of this study is to identify how firms' sustainability performance is affected by external knowledge sources and absorptive capacity, accounting for the influence of being located in a science and technology park (STP).

Drawing on data from the Spanish Technological Innovation Panel, the authors estimate the determinants of sustainability performance using fixed effects multiple linear regression models with robust standard errors. The analysis covers the period 2009–2016, with a total panel of 8,874 companies and a total sample of 47,870 observations.

This study highlights the heterogeneity in on-park firms’ sustainability performance, which can be explained by the different capacities of these firms when it comes to embedding themselves in STP networks and processes and effectively absorbing the knowledge from the many knowledge sources that may be on offer in the park.

This paper contributes to the literature by examining the influence of external sources of knowledge and absorptive capacity, and the relationship between them, on sustainability performance. This study approaches sustainability performance as an aggregate measure of firms’ competitiveness and potential for long-term survival from the triple bottom line perspective. In addition, this study examines the effect that location in an STP can have on business sustainability performance and, more specifically, the mediating effect that knowledge sources and absorptive capacity can exert on this relationship.
