摘　　要：在国家优化土地竞拍规则,稳地价、稳房价的政策目标下,提出了“限地价、竞房价”的土地拍卖机制。本文通过模型刻画了机制作用原理,得到了开发商的均衡投标策略,并与现有的第一价格密封拍卖机制做对比,得出了该机制对于调控房价有效性的条件。结果表明,若采用第一价格密封拍卖机制,引入了开发商对土地价格的竞争,土地成交价只取决于市场最高出价,得不到控制,从而造成房价居高不下;而采用“限地价、竞房价”的土地拍卖机制引入了对承诺房价的竞争,建设成本最低的开发商会以最低承诺房价赢得拍卖,拍卖单位可以设置合适的土地限价,有效地控制地价并降低房价。China's housing price-to-income ratio reach a new high of 9.2 in 2020.High house prices have exacerbated the housing problem of residents,reduced the purchasing power and fertility of residents,distorted the allocation of social resources,and has become a thorny social problem,which has also attracted great atten⁃tion of our country.As we all know,high land price is an important reason for high house prices.Therefore,optimizing land transfer rules is an important work at present.The existing land transfer often adopts the firstprice sealed-bid auction,but this“the highest price gets”land auction mechanism often leads to a high transac⁃tion price.Although local governments actively innovate land auction rules,the effect is not ideal.Therefore,the land auction mechanism of“Limiting land price and competing promised house price”is put forward,and the conditions for the effectiveness of regulating house price are given.The most commonly used land auction mechanism is analyzed,i.e.,the first-price sealed-bid auction mechanism,and the work of this mechanism causing high house prices is revealed.Secondly,the land auction mechanism of“Limiting land price and competing promised house price is put forward”.Finally,through the comparative analysis of the two mechanisms,the conditions for the effectiveness of the new land auction mechanism in regulating house prices are obtained.The results show that the first-price sealed-bid auction mechanism introduces the competition of bidders for land price,the bidder with the highest bid price wins,and the land transaction price completely depends on the highest bid price in the market,resulting in the high house price;On the other hand,when the land auction mechanism of“Limiting land price and competing promised house price”is adopted,the competi⁃tion of bidders for the promised house price is introduced,and the bidder with the lowest construction cost will win the auction.The government can effectively control the land price and reduce the house price by settin
