This study investigates how the circular economy and business models are related in the current business and management literature. Based on bibliometric analytical procedures, 253 articles were retrieved from the Scopus, Web of Science, and ScienceDirect scientific databases. The articles were analyzed according to network analysis principles, and key terms were mapped into a network. We used VOSviewer to build the network, explore the most-researched terms and their relationships, and identify less-explored terms and research gaps. We furthermore conducted a qualitative review of selected publications to provide an illustration of quantitative results and delve deeper into the research topics. The main findings revealed the networks of current topics as they appear in the publications such as business models, the circular economy, circular business models, value, supply chain, transition, resource, waste, and reuse, and their most prevalent relationships. The results also highlighted several emerging topics such as those connected with managerial, supply-side, demand-side, networking, performance, and contextual considerations of circular business models.

Purpose The purpose of this paper is to investigate the dynamics of digital entrepreneurship and the role of innovation ecosystem in its shaping by applying a multilevel perspective on the phenomenon. Design/methodology/approach An exploratory in-depth analysis of an IT company in Brazil is conducted using a quasi-mixed method design and three analytical techniques: pattern-matching, data exposure and social network analysis. The study is based on qualitative data, complemented by quantitative data. The case company is investigated within its time (historical development) and spatial (entire ecosystem) dimensions, providing an integrative approach to analysis. Findings The results revealed significant differences in a set of supporting innovation ecosystem’s actors and relationships throughout the development of the company from lower to higher levels of digitalization. The findings are discussed within a framework that links ecosystem’s actors at different layers with different levels of business digitalization. Research limitations/implications This research brings implications to SMEs in high-tech industries that are aiming to transform their business toward greater digitalization, and stresses the importance of strategic partners in innovation ecosystem in this process. Originality/value The novelty of this research is related to how external actors contribute to a company to adapt and create value, and how companies may exploit opportunities by configuring internal resources and external assets from strategic relationships. The study considers digital entrepreneurship in dynamics, distinguishes between different levels of digitalization and prescribes them different enablers and sets of relationships.

Purpose – The purpose of this paper is to explore the relationship between entrepreneurial orientation (EO) and firm performance across different levels of environmental hostility and market growth. The contingency approach of two-way interactions of EO with each environmental variable is contrasted with the configurational approach of three-way interactions of EO simultaneously with different levels of both environmental variables. Design/methodology/approach – Hierarchical regression analysis is applied for the pooled data set of 163 Finnish and Russian small- and medium-sized enterprises, and supplemented with post hoc analysis of the differences in regression slopes across environmental configurations. Findings – Results show that EO is directly and positively associated with firm performance. However, the strength and direction of this relationship varies by configurations of the external environment variables. Firms achieve superior performance when adopting EO in environments with high levels of both hostility and market growth. In contrast, in favorable environments with low hostility and high market growth, EO adoption leads to lower firm performance. Research limitations/implications – The study contributes to the EO literature by demonstrating different effects of EO on firm performance across various environmental configurations. It uses cross-sectional data from two countries. Replication studies using different samples may further corroborate the results. Practical implications – In order to take advantage of opportunities and achieve better performance, managers of firms should analyze multiple elements of the environment concurrently and align EO to those conditions. Originality/value – The configurations of environmental hostility and market growth, representing both favorable and unfavorable elements of business context, have not been previously investigated together in one model of the EO-performance relationship.
