中文摘要：

假设房产价格服从跳-扩散模型,研究分期付款看涨房产期权的定价问题.以北京西奥中心写字楼＂以租代售＂的实例为背景,在Black-Scholes框架下建立了实物期权定价的偏微分方程模型,推导出相应的二叉树格式离散模型,并进行数值模拟和参数分析,结果表明该模型较扩散模型更接近实际市场.

英文摘要：

The author investigates the installment call options pricing of real estate in jump-{diffusion} model.Under the background of ＂consignment to rent＂ of xi＇ao center office in Beijing,this {paper} establishes the real estate option pricing of partial differential equation model under the framework of Black-Scholes,and deduces the corresponding binary tree format,discrete model numerical simulation and parameter analysis.The results show that the jump-diffusion model is closer to the real market than the diffusion model.
