Using market monopoly to raise prices to restrict the development of new entrants is an unfair and possibly illegal act, which will damage fair market competition and consumer interests. Such behavior should not be encouraged or implemented. However, from a theoretical perspective, there may be some manifestations as follows: 1. **Overpricing**: Relying on monopoly advantages to significantly increase product or service prices, making it difficult for new entrants to compete with them on cost. If new entrants sell at similar prices, they may not be able to make a profit. If they sell at lower prices, they may be suspected of product quality, etc., thereby hindering their entry into the market. 2. **Predatory pricing strategy**: In the early stage of new entrants entering the market, they significantly reduce prices in the short term or even sell below cost to exclude new entrants. When new entrants withdraw, they resume monopoly high prices. However, this behavior has legal risks. 3. **Price discrimination**: Different prices are implemented for different customer groups or regions, making it difficult for new entrants to accurately grasp the price system, increasing the difficulty of entering the market and competing. 4. **Bundling of high-priced products or services**: bundling some high-priced or low-demand products or services with core products. If new entrants do not accept bundling, they may be at a disadvantage in their core business. If they accept, their cost burden will increase. In reality, the government has cracked down on such unfair competition through anti-monopoly laws and regulations to maintain the healthy and orderly development of the market.
