Academic entrepreneurial engagement for frugal innovation in higher education institutions: a systematic literature review

Higher education institutions (HEI) are faced with increasing challenges related to shrinking resources, high operation costs, the COVID-19 pandemic, decreasing student enrolment rates, and pressure to contribute to regional development and economic growth. To overcome such challenges, academics must move beyond their traditional functions of research and teaching and engage in entrepreneurial activities. Through engagement in entrepreneurial activities, academics can contribute to frugal innovation (FI) in private HEI (PHEI). The literature in this context emphasizes that academic entrepreneurial engagement (AEE) will lead to innovation, the identification of opportunities for new business ventures, financial rewards for institutions and academics, an impact on the economy, and the enhancement of social welfare. This study presents a systematic review of the literature and adopts the Transfield five-phase strategy to review the literature on AEE from the past two decades (2000–2020). A total of 1,067 papers on FI are obtained, only five of which focus on AEE. Moreover, papers related to AEE for FI are few. The study presents the research gaps, challenges, and potential factors for further research in this context. We conclude that FI for AEE in PHEI can be a game-changer for future sustainability. Moreover, we believe that the outcome of this review warrants further research.


Introduction
Private higher education institutions (PHEI) play an important role in a nation's economic development and prosperity by supplying skilled workforce and generating basic knowledge for solving societal problems.Notwithstanding their strategic contributions, PHEI are challenged by dwindling resources and the need to contribute to the economy and social development. 1For instance, in Malaysia, PHEI are faced with rising operating costs, pressure to increase their global ranking, drop in student enrolment, problems in balancing teaching and research task allocation, decreasing government funding and shrinking budget allocations for staff development and empowerment programmes. 2 Many PHEI in Malaysia incurred losses for years and are unable to access adequate capital. 3A recent report revealed that 55% of Malaysia's PHEI incurred losses, and approximately 44% were financially insolvent.As a result, more than 5,800 academics are faced with an uncertain career outlook, and approximately 121,000 students are at risk of receiving poorquality education. 4Besides, PHEI depend mainly on student fees to offset their operating costs.However, funding sources continue to decline.The annual budget of the National Higher Education Fund Corporation, which is a major provider of educational loans in Malaysia, was severely reduced owing to the high default and low repayment rates of existing loans. 4Thus, to survive, PHEI management must devise effective strategies to attain financial stability amidst dwindling resources.
Furthermore, the COVID-19 pandemic created additional challenges and heightened the impact of existing problems encountered by PHEI.The Movement Control Order (MCO) and border closure policy to curtail the spread of COVID-19 resulted in a drop in student enrolment.Specifically, international student enrolment declined drastically owing to students' inability to gain entry into the country. 5Prospective students also deferred or delayed their studies, whereas others were unable to pay tuition fees owing to loss of jobs and the economic recession.Inevitably, this situation will further put a strain on the cash flow of institutions 5 and the economy.These challenges indicate the urgent need for PHEI management to restrategise to enhance their output and quality amidst dwindling resources.
In coping with the challenges associated with resource constraints and adversities, academics are expected to venture beyond their traditional responsibilities of conducting research, accomplishing administrative tasks and performing teaching activities and engage in entrepreneurial activities. 6By fostering entrepreneurial practices among academics, PHEI can stimulate innovative outcomes to improve economic growth, create jobs and research opportunities for graduates and support the educational ecosystem. 7][10] The literature ascertains the role of individual academics 11 through their effective transfer of knowledge to form new ideas and inventions that can help universities achieve their entrepreneurial mission and promote sustainable development.Hence, researchers have started paying attention to factors influencing university faculty members' entrepreneurial intention and behaviour. 12ademic entrepreneurial engagement (AEE) entails the commercialisation of scientific knowledge, including the transformation of knowledge into products and processes that may inevitably contribute to economic growth and innovation.AEE refers to academic engagement in activities beyond the traditional functions of research, administration and teaching, including formal and informal activities, such as collaborations with businesses and industries, new-firm creation, research output patenting, invention disclosures by academics to technology transfer offices, academic knowledge transfer, research output licensing, contract research, consulting, research collaborations, knowledge transfer mechanisms, student placements, training and continued professional development, leading to financial rewards for individual academics and institutions. 13Academic engagement in entrepreneurial activities supports knowledge transfer and technology commercialisation and can contribute significantly to entrepreneurial ecosystem development.
AEE is underscored by capability factors such as entrepreneurial-related abilities, education, human capital and industrial experience. 14Hence, previous studies have explored the individual, organisational and institutional determinants of academic entrepreneurial intention. 15,16Moreover, studies have examined the various forms of AEE, such as spinoffs, firm creation, licenses and joint ventures and so on. 15,16Other studies have investigated the factors motivating individual academics to start a business, such as their work routine, need for independence and desire to become wealthy.

REVISED Amendments from Version 2
Major difference is : -Provided justification for the selection of only peer-review papers in this study.
Any further responses from the reviewers can be found at the end of the article Researchers have also examined the determinants and outcomes of academic entrepreneurial intention. 14Nevertheless, insights into the antecedents and outcomes of academic entrepreneurial engagement (AEE) have received limited attentions.
8][19]  Kodithuwakku et al.  (2012)  20 argued that in a resource constrained environments entrepreneurial skills are key to discovering opportunities.Earlier studies 21 identified limited resources as a push factor that motivates academics to be entrepreneurial to overcome resource barriers.Findings from 22 reveals that academic entrepreneurs operating in resource constrained environments sees every opportunities to engage in entrepreneurial activities.De Silva et al. (2012)  22 reveals that limited resources do not limit academic engagement in entrepreneurial endeavour but help academics consider being entrepreneurial as a means to be resource-rich.It is also revealed that academics gradually diversify their engagements, and due to limited opportunities, they tend to engage in unrelated diversification.Thus, academic engagement in entrepreneurial activities can help enhance university global performance through frugal innovation (FI).
FI is also known as jugaad innovation, which demands rapid and rational adaptability to changing conditions. 23,24FI changed the nature of innovation as the 'ability to accomplish more with less', resulting in increased economic and societal value whilst reducing resource consumption. 24The main characteristics of FI are based on cost dimensions, such as reducing costs or purchase prices and the overhead on nonessential activities, increasing 'value proposition', decreasing unnecessary functions and features that are non-value adding and minimising the use of resources. 25,26herefore, FI could enable significant reduction in resource consumption whilst achieving superior-quality standards and considering the goal of creating a frugal environment.The concept of FI requires further in-depth research using conceptual and empirical techniques.
In higher learning institutions (HLIs), some academicians and management personnel emphasise teaching and learning, student services and community participation, whereas others are concerned with achieving national goals by developing industry-oriented technical innovation, interacting with businesses and engaging in technology transfer.Clearly, HLIs contribute by engaging in R&D collaboration, skills development training, commercialisation through spinoffs and the co-creation of knowledge and ideas and entrepreneurial and technical expertise to overcome community challenges and attain national goals.Hence, emphasis is placed on exploring FI principles as a game changer for the sustainability of PHEI.
Overall, this paper contributes theoretically in terms of gaps exists in frugal innovation for AEE pertaining to motivation, opportunity and ability of academics in PHEI.Further research will help to grow the body of knowledge and enhance theory related to motivation, opportunity and ability to support AEE in PHEI.In terms of practical contribution, this research warrants attention of PHEI to further adopt frugal innovation to create sustainable practices through AEE.Our further research are focusing on how this can be implemented to turbocharge the formation of IR4.0 education eco-systems.
Against this background, this study will provide academic researchers with insights into what has been done with regard to FI for AEE and PHEI to prioritise the factors that can influence AEE for FI in PHEI.In particular, we aim to achieve and provide answers to the following questions; 1. Does a research gap exist in AEE studies to support FI pertaining to motivation, opportunity and the ability of academics in PHEI?
2. What are the challenges encountered by academics and the key factors influencing the pursuit of entrepreneurial initiatives in PHEI?
3. Can AEE for FI be a game changer for supporting constraints in PHEI?
In addressing these questions, we examined 1,067 papers on FI for AEE in PHEI and identify four major gaps in the literature.We believe that our findings warrant the attention of the research community.In particular, we make significant contributions to theoretical understanding by providing researchers with insights into what has been done with regard to FI for AEE.Findings from this study will offer academic entrepreneurial communities a series of research ideas to advance the field and enable PHEI to know the key factors that influences academic entrepreneurial engagement and the various challenges that hinder them in engaging in entrepreneurial activities.Therefore, PHEI will be able to prioritise the factors that can influence AEE for FI in PHEI.In summary, this study is envisaged to have practice implication for PHEI, in their attempts to leverage AEE for FI.

Methods
This paper was designed to present the identified research gaps and insights to examine FI as a game changer for AEE.
Based on the literature, key factors influencing AEE to achieve FI in HLIs were explored.This literature review was based on the five stages of the systematic review as illustrated in Figure 1 proposed by Tranfield et al., 2003. 27 Stage 1. Planning the review This review aims to identify the research gaps, challenges and factors supporting FI for AEE in PHEI.In addition, this review aims to offer researchers a comprehensive review of previous works related to FI to support AEE initiatives, specifically in the form of a conceptual framework.Finally, the outcome of this review process will offer academic entrepreneurial communities a series of research ideas to advance the field.

Stage 2. Identifying and evaluating studies
In this stage, papers were examined for the selected keywords.Specifically peer review papers because it focuses on current trend and have also gone through expert review.The keywords included general key terms ('AEE') regarding    specific keywords ('FI for AEE in PHEI').The focus of this review is to analyse research on AEE in PHEI.The factors and challenges mentioned in the literature were further classified into several categories.

Inclusion and exclusion criteria
Figure 2 shows the inclusion and exclusion criteria for selecting the papers.The selected papers were those published in the past two decades, peer reviewed, related to AEE focusing on FI and of scholarly origin and either conceptual or empirical papers.

Keywords
We focused on six major research areas, namely, (1) AEE, (2) FI, (3) institutions of higher learning (IHL), (4) motivation, (5) ability and ( 6) opportunity.For the first area, we included terms such as 'Academic Entrepreneurial Engagement' and 'Frugal Innovation'.Each keyword set was combined with other keywords.Table 1 presents the keyword sets used for this research

Search strategy
The strategy used to collect the papers was based on five major online databases.The online databases were selected based on their wide range of social science research.Table 2 presents the results based on all the sources mentioned above and keyword sets.A total of two papers were listed when we used the keyword 'Academic Entrepreneurial Engagement'.When we searched for 'FI', 1,067 papers were retrieved.When we used the keywords 'AEE' AND 'Motivation', two papers were listed.However, no papers were retrieved when we used 'AEE' AND 'Opportunity' and 'FI' AND 'AEE Ability'.Finally, 'AEE' AND 'Ability' listed one paper.After careful selection based on the inclusion and exclusion criteria described above, we identified five papers relating to AEE and FI.

Stage 3. Extracting and synthesising data
From the sources mentioned above, we extracted the papers based on the extraction process in Figure 3.

Summary of five core papers
The five papers were from public HEI and based on Tables 3 and 4, our findings revealed that no research was conducted in the area of FI for AEE related to motivation, opportunity and the ability of academics in PHEI.Most of the studies focused on factors shaping academics' entrepreneurial intention, exploring individual, organisational and institutional variables. 15,16The studies on academic entrepreneurial intention were conceptualised from different theoretical perspectives, including theory of planned behaviour (TPB), social learning theory and motivational theories.Based on TPB, academic attitude, subjective norms and behaviour control were associated with entrepreneurial intention. 28,29Moreover, other factors such as perceived feasibility and desirability were determined to influence entrepreneurial intention, leading to actual behaviours. 9Therefore, further research is necessary to explore the role of motivation, ability and AEE opportunity for FI.

Challenges and factors Challenges
Several challenges constrain academic engagement in entrepreneurial activities.Such challenges were categorised as individual factors, which constrained personal engagement; organisational factors, which were structural and systemic inhibitors of engagement; and process factors, which included institutional policies detrimental to academic entrepreneurial behaviour.
Based on Table 5, existing studies highlighted the need for academics to assume job responsibilities beyond teaching and research as a major challenge to their engagement in entrepreneurial activities. 14Academics are expected to extend their research output to products and services suitable for the industry and society.Thus, their research outcomes should be commercialised by creating new firms without breaching current laws that govern their role within the university. 30 Academics are challenged to develop the appropriate competencies to become entrepreneurial to help create a firm.Competence refers to the academic ability to identify resources to start a business. 22In addition, understanding the dynamics shaping the development of entrepreneurial competencies can improve capabilities to maximise resource use through FI, which means 'accomplishing more with less', thereby resulting in increased economic and societal value whilst reducing resource consumption. 24

Factors
Previous studies determined the relevant factors related to AEE.Regarding socioeconomic characteristics, gender, age, income and personality (proactiveness and optimism) were associated with academic entrepreneurial behaviour. 31Drawing on TPB, Wang et al. 32 investigated the role of academic output and prior experience as individual factors and university reputation and supportive climate as organisational factors influencing AEE. 33identified cultural factors as contextual inhibitors of academic competencies for entrepreneurial engagement.These studies are further summarised in Table 6.

Discussion
The discussions are described in Table 7 to answer the research questions as shown below.
Limitation of this study is on the number of keywords selected.Keywords selections are based on research focus.However, there is possibility of obtaining more articles if the keywords are expanded to field of study that are not specific in nature such as intention.This could possibly be publication bias.

Future research
We recommend future research to consider the following topics: • AEE factors involving the COVID-19 MOC and other related aspects • AEE for FI in PHEI focusing on adult learners • AEE using qualitative methods that may unveil in-depth knowledge within this context based on actual academic entrepreneur case studies

Conclusion
The purpose of this study is to notify academic entrepreneurial communities of the disparity in the implementation of FI to enhance AEE in studies published in the past 20 years.Our paper is based on an extensive review of the literature and the application of a methodology that includes five stages.This methodology is used to determine the scope and nature of FI to promote AEE.Despite the sizeable search result of 1,067 papers in the AEE domain, our search record is limited to five papers investigating FI for AEE.Based on our rigorous review of the five papers, we recommend further comprehensive research to determine whether FI is related to AEE and identify the challenges and factors supporting FI for AEE in PHEI and additional empirical work.
PHEI that can achieve FI will be able to enhance their AEE and contribute to the economy and social development, thereby creating IR 4.0 educational ecosystems.
Research gaps in studies on FI for AEE pertaining to motivation, opportunity and ability of academics in PHEI Based on Tables 3-6, our findings revealed that little research was conducted in the area of FI for AEE related to motivation, opportunity and the ability of academics in PHEI.The mapping in Table 4 clearly indicates the scarcity of research on FI, motivation, opportunity and ability.

Challenges faced by academics and key factors influencing pursuit of entrepreneurial initiatives in PHEI
Based on the literature review of the various factors and challenges faced by academics in pursuing entrepreneurial initiatives in PHEI, we emphasised that attention should be paid to factors determining AEE, as few researchers examined the challenges faced by academics in developing the appropriate entrepreneurial competencies.The adoption of an FI mindset in AEE can create an opportunity to mitigate the identified challenges.FI minimises resource consumption and costs to attain high productive outcomes.

FI as a game changer for PHEI to improve AEE
AEE is a crucial factor, as PHEI must utilise their internal capabilities to promote FI through idea generation and relate them to their innovation ecosystem environment and the overall institutional structure.The scientific and technical competencies of universities will foster FI through the efficient use of resources under constrained environments and enable them to venture beyond the local market.Therefore, apart from their traditional mission and norms, PHEI that can realign their strategies to focus on sustainable societal development and address societal problems through academic research can enable FI.To develop FI in PHEI, AEE across various university community dimensions (academicians, scholars, faculty or the university) and collaboration with external stakeholders are necessary.Hence, PHEI will be able to integrate social, FI and environmental objectives through open innovation strategies via knowledge transfer and collaboration to produce patents, copyrights, intellectual property and spinoffs and startups with industries, business associations, the government, NGOs and communities rather than merely focusing on traditional financial objectives.As a result, PHEI must aim to promote teaching, research and community outreach activities that focus on achieving societal goals and contributing to FI to support AEE.

The paper deals with an original and interesting topic.However, it is flawed in many respects.First of all, the introduction is much larger than the other sections, including the literature review.
Secondly, the discussion of the results is superficial.Third, it lacks of focus.Therefore, I must recommend its indexing only after major revisions.

Comments:
Since the paper is focused on FI in AEE, I would redraft the introduction accordingly.At the moment, it is largely focused on AEE.Moreover, the authors shift form AEE to FI without mentioning innovations.For me, the focus should be on academic R&I and on FI.

○
Why the focus on private institutions?It might be relevant for Malaysia, but it is definitely not for the majority of other countries.At least there might be a difference in meanings.
Please put this limitation into context and discuss better the generalizability of results to other countries.

○
Why did the review omit students' engagement?Scholars in many countries have concluded that students represent one of the most valuable source of AEE.

○
What are the keywords used in the literature review?Notwithstanding the relevance of FI for academia, searching for "frugal innovation" might underestimate considerably the magnitude of the phenomenon.The "search strategy" section is not sufficiently clear.

○
The implications and discussion are too superficial.
