This is a book about industrial geography and economic uneven development. It explores the mechanisms of industrial location, the changing form of the inequalities between cities and regions, and the importance of these things to the economy and society more widely. This forms its empirical focus. However, it became clear as I was exploring these issues that what we needed above all was a new way of thinking about economic space. We need, or so I argue in this book, to think of economic space as the product of the differentiated and intersecting social relations of the economy. It is with this way of conceptualising economic space that much of the book is concerned. Such an approach influences the way we analyse the location of economic activity, the way we understand uneven development, the way we conceptualise individual areas (places), and the approach we may take to any attempt to tackle the inequality — the relations of dominance and subordination — currently inherent in all these things. Let me begin, then, with the central nub of this argument.
