With the rapid development of internet platform enterprises, the skewed pricing model for these enterprises has been widely used and has become a research focus. When the overall price level is stable, the price structure directly affects the volume of business, thus a proper pricing mechanism turns into an important factor influencing the development of internet platform enterprises. The theory of two-sided markets was applied to construct a pricing model that explains the economic principle of how the demand-price elasticity and the cross-network effects of two-sided markets influence the pricing of internet platform firms, and finally develop the optimal price structure and total price level. Also, a case study of Uber was made to discuss the skewed pricing methods and subsidy strategy used by internet platform enterprises, which provides a reasonable explanation for the examples of skewed pricing in real life.
