Chapter 5 Product Differentiation versus Geographical Differentiation: Evidence from the Pork Processing Industry in China

This chapter attempts to identify whether product differentiation or geographical differentiation is the main source of profit for firms in developing economies by employing a simple idea from the recently developed method of empirical industrial organization.Theoretically, location choice and product choice have been considered as analogues in differentiation, but in the real world, which of these strategies is chosen will result in an immense difference in firm behavior and in the development process of the industry.Development of the technique of empirical industrial organization enabled us to identify market outcomes with endogeneity.A typical case is the market outcome with differentiation, where price or product choice is endogenously determined.Our original survey contains data on market location, differences in product types, and price.The results show that product differentiation rather than geographical differentiation mitigates pressure on price competition, but 70 per cent secures geographical monopoly.
