The Structure, Function, and Evolution of a Regional Industrial Ecosystem

A framework has been developed to assess the structure, function, and evolution of a regional industrial ecosystem that integrates insights from industrial ecology and economic geography dimensions with complex systems theory. The framework highlights the multilayered landscape of natural ecosystem functions, economic transactions, policy contexts, and social interactions in which interfirm collaboration evolves. Its application to a single case study on the island of Puerto Rico revealed changes in the system's institutional context, its resource flows, and the composition of its industrial community. It illustrated that external forces and interactions among actors at multiple levels can cause permanent changes-but not necessarily system collapse-as policy choices and interfirm cooperation can be used to organize resources in ways that retain system functionality.
