The paper by Ron Martin and Peter Sunley explores the concepts of "path dependence" and "lock-in" in the context of regional economic evolution. They argue that these concepts are place-dependent processes and require geographical explanation. The authors highlight unresolved issues surrounding path dependence, such as the different types and degrees of path dependence, and the relationship between path dependence and lock-in. They also discuss the application of evolutionary economic concepts in economic geography, emphasizing the need for a geographical perspective to understand how geography influences economic evolution. The paper further examines the concept of regional path dependence, questioning what it precisely refers to and how it varies across different regions. It concludes that while path dependence is an important feature of the economic landscape, it requires further elaboration to function as a core concept in evolutionary economic geography.The paper by Ron Martin and Peter Sunley explores the concepts of "path dependence" and "lock-in" in the context of regional economic evolution.
