Abstract: Formulating a reasonable product positioning and pricing strategy is of great significance in corporate marketing management. In this paper, on the condition that there are two cross-shareholdings enterprises with quadratic transportation cost in a linear market, an extended Hotelling model is firstly built. In the model, two enterprises make simultaneously price-decisions after their location-decisions are made simultaneously. Then some equilibrium analysis and discussion on the parameters in the model are developed. The results of theoretical analysis show: With the growth of shareholding ratio, enterprises will produce more differentiated products to obtain more profits, and the speed is faster and faster; With the growth of shareholding ratio, the price of products will gradually increase, and the rate will grow faster and faster. Thus the conclusions in this paper will further enrich the existing theoretical results of the Hotelling model, and offer support for enterprises to determine their shareholding ratio and to construct their product positioning and pricing strategies.
