Purpose -Because the business model (BM) is a fairly new concept, research is lacking on business model innovation (BMI) in certain industry sectors. One such sector is the agri-food sector. Using a systematic literature review (SLR) of peer-reviewed journal articles published from 1990 to 2014, the purpose of this paper is to examine the where, when, and how of the use of BMs and BMI in the agri-food sector. Design/methodology/approach -A web-based search was conducted to identify peer-reviewed journal articles that contained a combination of "BM" or "BMI" with agriculture-related and foodrelated terms (e.g. "agri-food sector"). After winnowing out irrelevant and duplicate articles, 505 articles were chosen for analysis. Findings -Using categories, the paper analyses various data about the selected articles. The categories include research settings, units of analysis, methodologies, and theories. Based on this analysis, the paper finds that these agri-food sector articles are primarily qualitative, empirical studies that focus on one or a few companies (i.e. case studies). The paper also finds that theory is not yet well-developed in the research on the agri-food sector. Originality/value -SLRs of various concepts, theories, and models are common in many fields (e.g. information/software technology, healthcare, and organizational management). However, no such review is available for the agri-food sector, in particular in its use of BMs and BMI. This paper addresses that gap with its review of relevant articles published in more than 300 journals in recent years. Based on this review, the paper draws conclusions about BMI in the agri-food sector and offers suggestions for future research.

The purpose of this paper is to explore the evolution of the concept of corporate social responsibility (CSR) in academia. The process of evolution is conceptualised to consist of diffusion and dynamics. Bibliometrics were applied for data collection and visualisation of the evolution of CSR. The findings show increasing complexity and progression in the research on the concept of CSR fuelled not only by the efforts for intellectual refinement in the field but also reflecting the changing priorities of society and businesses. The growth of this field of research both in number of publications (i.e. diffusion) and in terms of different fields in academic usage (i.e. dynamics), is an indicator for growing complexity and widening acceptance of the CSR concept across various academic disciplines in the future.

The importance of business model innovation (BMI) is widely recognized. BMI is especially important in the agri-food industry that faces enormous challenges as the demand for food increases worldwide. Much of the BMI research focuses on the technology and biomedical industries. Far less attention has been paid to the agri-food industry. This article is a systematic literature review of the BMI research in the agri-food industry. The article’s aim is to identify and categorize various barriers to BMI as described in the literature (in English) published in peer-reviewed journals between 1990 and 2014. The findings show a fairly even distribution among external and internal BMI barriers. Because the main barrier is the mind-set that is resistant to change, it is recommended the researchers and practitioners should focus more on the cognitive barriers to BMI in the agri-food industry.
