How to measure change in a complex system? Keep an eye on diversity

"One of the most respected attempts to measure complexity was made ten years ago by John Tyler Bonner, a biologist at Princeton University in New Jersey. Count the number of different types of cell in the organism, he suggested. In principle, this gives a sense of the number of specialised functions an organism can perform, and that is a clue to complexity. Although it leaves out behaviour, the approach also has the virtue of considering the whole organism, not just one part." (Roger Lewin, New Scientist, 05 Feb 1994)

This idea makes me think that diversity could be used as a key indicator of structural change in a market system. How many different private and public actors are there in a market system at different points of our interventions? Moreover, diversity presents fractal properties: one could look at diversity within the system, the value chains within the system, the types of actors within the value chains, and variations within a given type of actor.
