After more than a decade Michael Porter's book Competitive Advantage of Nations stays ahead of the other books, in particular as alternative framework from the comparative advantage idea inspired by Adam Smith. This small book is merely an alternative proposition, a postscript perhaps, to Porter's book, with basic idea that one cannot rely merely on industrial processes alone to keep stay ahead of market changes. Hence, for cities in developing countries the municipal shall find out their city's best resources, and develop their city starting from there, instead of striving blindly in the conventional industrial path.
