我国股票和房地产市场的财富效应研究——基于状态空间模型的实证分析

研究了柴油机低速部分负荷工况引入不同EGR对缸内燃烧排放特性的影响. 将CHEMKIN-Ⅱ化学反应求解器集成到KIVA 3V Release 2程序中, 用正庚烷化学反应机理替代柴油燃烧, 建立柴油机缸内燃烧数值模拟模型; 结合试验数据, 模拟分析喷油时刻保持不变, EGR率（废气再循环）从0%增加到 60%的燃烧过程、NOx和碳烟排放. 结果表明: 引入大比例EGR后点火延迟明显增长, 燃烧相位推迟, 燃烧温度降低; 较低燃烧温度避开了NOx的高浓度生成区, EGR率60%时NOx排放比无EGR时降低93.5%; 但高EGR率未使燃烧路径避开碳烟生成区, 加之较低的氧浓度不利于碳烟的氧化, 碳烟排放增高.

The Wealth Effect of Stock Market and Real Estate Market in China: An Empirical Study Based on the State Space Model

In the paper, the state space model and impulse response functions have been used to analyses the time-varying characteristics of the wealth effect of stock market and real estate market. It is found that in the long term the stock market has the stability of tiny negative wealth effect, and the estate market has the stable positive wealth effect. The wealth effect of real estate is larger than the stock. At the same time, the outbreak of European debt crisis at the end of 2011 almost has no effect to these two kinds of markets'' wealth effect. At last, the policy recommendations have been put forward about gradually increase stock returns of dweller, maintain operation about the real estate market price smoothly, and strive to improve the income level of resident.
