Despite its relative newness, entrepreneurial ecosystems (EEs) have attracted much attention from research and policy but they are recognized to be largely untheorized. It is claimed that one aspect which distinguishes the EE perspective from other perspectives related to business environments is its systemic approach; however, much of the systemic approach still needs to be investigated. The aim of this paper is therefore to investigate how the systemic and complex approach of EEs can be theoretically strengthened. We do this by investigating what values complex adaptive system theory holds for advancing the EE perspective. We highlight four propositions which are of particular importance for strengthening the systemic approach of EE: spatial and component boundaries of the system; self-governance; the relational dimension between system components and the system; and the evolution of the system. We propose that boundaries should be seen as a natural part of the system, that a complex system is too complex to capture all components and all interactions, and that studying only individual activities will not enable us to fully understand the system's behaviour.

This article casts light on the development of new regional industrial paths. We explore factors explaining why regional industries with similar early path development trajectories may exhibit diverging outcomes in the longer run and pay particular attention to the role of ‘outsiders’ in the initiation and further development of regional industrial paths. Drawing on a comparative case study of IT industries in Linköping and Karlskrona, two medium-sized Swedish city regions, we find that the inflow of outsiders was an important driver of early path development processes. However, we find that the interplay between regional preconditions and arriving outsiders, and between outsiders and existing actors, substantially shaped the long-term sustainability of the industrial paths in our study. In particular, the role of agency in fostering positive self-reinforcing mechanisms and structure–agency dynamics are highlighted as key factors for understanding how new industrial development paths are unfolding in the longer term. © 2018, © 2018 The Author(s).

Path dependence has claimed its place as a core component of economic geography, but recently the concept has been criticized for the sole focus on external shocks and lock-ins. This critique has inspired scholarly work on new path development which gives great attention to endogenous pre-conditions for new path development. However, several shortcomings still exist. The main aim of this chapter is to enhance the concept of regional path dependence by suggesting a stronger role for human agency. This would address several of the remaining shortcomings. In order to move towards a more agency-centred view of regional path dependence, we have to take on a structure–agency approach, transcend the purely technological dimension of path dependence, shift from a few grand events to the activities of many agents and include both economic and public actors.

This dissertation deals with the rise of new industries through entrepreneurial activities. The aim is to investigate how differences in contexts might encourage or discourage entrepreneurial activities. This contextualization of entrepreneurship enhanced our understanding of when, how and why entrepreneurial activities happen.

Entrepreneurship is recognized to be a spatially uneven process and, in addition to previous research that has examined the actions of individual entrepreneurs, we also need to understand the context in which entrepreneurship occurs. We have a good understanding of how structural conditions like industry structure, organization structure and agglomeration effects influence the context, but we know little about how the social dimension of the context is the transmitting medium between structural conditions for entrepreneurship and the decision to act upon identified entrepreneurial opportunities. Following this line of argument, this dissertation is built on the assumption that entrepreneurship is a social phenomenon which gives strong arguments for including local culture in entrepreneurship research.

The temporal persistence and the pronounced differences of culture and structural conditions between places reflect path-dependent processes. I therefore use regional path dependence as an interpretative lens to study the contextualization of entrepreneurship in two Swedish cities.

Although each context is unique, some generalizations can be drawn from the four individual papers in this dissertation. The first is that industrial legacy leads to the formation of a distinct local culture and that the persistency of this culture influences the subsequent entrepreneurial activities in new local industries. The second is that this persistency of culture suggests that entrepreneurs who are outsiders, geographically or socially, are the driving forces for the emergence of new local industries. Finally, new industry emergence is a result of a combination of exogenous forces and initial local conditions, but it is the entrepreneurial individuals who translate these forces and conditions into entrepreneurial activities.

This paper examines how an industrial legacy leads to the formation of a distinct local culture and how the culture’s survival provides a context for the subsequent entrepreneurial activities in new local industries. The discussion about culture as a key driver of entrepreneurship and economic growth is well established in the academic debate. However, we know little about how culture is formed. Through a qualitative case study of two polar Swedish cities, the study highlights four key factors which are instrumental in the formation of local culture: initial conditions, characteristics of key players, network activities and composition of newcomers. We show how the local entrepreneurs responded to the underlying assumptions of the two different cultures.

Few attempts have been made to consider the role of individual activities in path dependence. The purpose of this paper is to analyse how local entrepreneurial activities can lead to a break in the cognitive local path. The theoretical framework rests on the literature on path dependence, but focuses mainly on cognitive frames as carriers of path-dependent behaviour. A qualitative case study has been used to analyse the formation and breaking of a local cognitive path through individual activities. Four main conclusions can be drawn. First, cognitive paradigms explain why the degree of adaptability differs between locations. Second, external shocks are translated to local change through individual activities. Third, acknowledging cognitive barriers to individual behaviour, the important role of outsiders is highlighted for breaking the cognitive path. Fourth, the long durability of cognitive paradigms and the importance of outsiders suggest the emergence of a parallel, alternative cognitive path.

This paper uses path dependence as an interpretive lens to examine the relationship between innovative entrepreneurship and regional development. A literature review of path dependence explains why that concept is relevant for this paper. This paper reaches four conclusions about the relationship. First, in the study of innovative entrepreneurship in a regional context, the technological, social and cognitive dimensions should be taken into consideration. Second, the effect of the different types of innovative entrepreneurship on path dependence depends on specific, regional situations. Third, the dominant regional network forms an institutional foundation that may either hinder or support innovative entrepreneurship. Fourth, innovative entrepreneurs who introduce new knowledge from outside the region are more likely to alter the regional path.

This article aims to analyse how innovative, individual actions influence the evolution of local industries according to three stages. When discussing the evolution of industries or economies, the concept of path dependency is often a central element. Its vague nature makes it however difficult to be used as an interpretative lens when studying the evolution of local industries. In order to limit the broad concept, several aspects have been identified for discussion; all are explicitly linked to path dependency in economic geography literature and all are acknowledged to be of significance for stimulating the evolution of local industries. Based on a review of the evolutionary economic theory literature, the following three stages have been identified: First, the entering of new knowledge which may, or may not, be the starting point for a new local industry; second, the formation of the new local industry; third, the anchoring process of the new local industry. All three stages are intertwined and include the question how the new emerging industry and the existing local structures relate to each other. The three stages will be illustrated through the discussion of the evolution of the IT industry in Linköping, Sweden.
