The main purpose of this paper is to examine the adoption of big data analytics (BDA) in the Tanzania banking industry by investigating the influence of technological, environmental and organizational (TOE) factors while exploring the moderating role of perceived risk (PR).

The study employed a qualitative research design, and the research instrument was developed using per-defined measurement items adopted from prior studies; the items were slightly adjusted to fit the current context. The questionnaires were distributed to top and middle managers in selected banks in Tanzania using the snowball sampling technique. Out of 360 received responses, 302 were considered complete and valid for data analysis. The study employed partial least squares structural equation modeling (PLS-SEM) to examine the developed conceptual framework.

Top management support and financial resources emerged as influential organizational factors, as did competition intensity for the environmental factors. Notably, bank size and perceived trends showed no significant impacts on BDA adoption. The study's novelty lies in revealing PR as a moderating factor, weakening the link between technological readiness, perceived usefulness and the intent to adopt BDA.

This study extends literature by extending the TOE model, through examining the moderating roles of PR on technological factors. Furthermore, the study provides useful managerial support for the adoption of BDA in banking in emerging economies.

The banking system in Nigeria is gradually moving away from transactions “across the counter” to the fingertips of the customers with the adoption of modern technology. However, every development comes with its “pros and cons” because as technology innovation has improved service delivery and profitability of banks in Nigeria, crimes are also at a high side. To activating the minds of bank operators about the importance of technology adoption and its shortcomings, this paper aims to examine the prospects and challenges of technology innovation in the Nigerian banking system.

Secondary data were retrieved from the annual reports of Central Bank of Nigeria (CBN) and Nigeria Deposit Insurance Corporation (NDIC) from 2013 to 2017 to know the interaction between e-banking platforms and performance of banks in Nigeria. The study administered a questionnaire to the bank customers in Lagos Island, Nigeria to understand their perception towards e-banking. This study is anchored on prospect theory to ascertain the risk orientation of the Nigerian banks regarding how they adopt technology and reasoned action theory to understand the intention of bank customers in using the opportunities of e-banking copiously.

The findings of this study reveal the migration from cheques to electronic related transactions. It further indicates a high rate of fraud committed through those channels. The analysis of primary data shows that innovation adoption, service quality, cybercrime have significant relationship with the competitiveness of banks, the intention of bank customers, and perception of customers towards online services. However, the rate of frauds does not have significant relationship with the usage of mobile banking products which further studies can critically examine.

This study has revealed available huge potentials in the e-banking that are yet to be used in Nigeria. However, consumer orientation needs to be worked on, because, customers still have the fear that cybercrime is mostly committed via e-banking platforms. Unlike in developed countries whereby quite good numbers of customers make use of e-banking platforms, majority of bank customers in Nigeria still prefer using manual methods and the world is already on the verge of moving into 5 G from 4 G.
