Fixed-effect model ( FEM) and random-effect model ( REM) of Meta-analysis were applied to process data. 统计处理采用Meta分析的固定效应模型和随机效应模型。
The fixed-effect regression indicates that debt plays a negative role in making profits while the effect of debt maturity structure is positive, the negative effect of debt is more serious than the positive effect of debt maturity structure. 固定效应的变截距模型的回归结果表明负债对盈利起负的作用,而长期债务对企业盈利则起正的促进作用,并且资产负债率对企业盈利的影响比债务期限结构的影响要大。
Based on the real estate development statistical data of 30 major cities, this paper chooses absorption rate as judging market equilibrium indicator and does some research on the structure difference of urban housing market with fixed-effect variable intercept model. 依据中国30个主要城市的房地产开发统计数据,选择吸纳率作为评价住宅市场供需均衡状态的指标,利用固定影响变截距模型,重点研究了商品房和经济适用住房供给结构的城市差异性。
By the panel data of 31 provincial districts in China after the reform and sectional fixed-effect method, the dissertation makes an analysis on the relations of macro-fluctuation of housing price and income, employment, mortgage interest rate and construction cost. 采用住房基本制度改革后我国31省级行政区1999&2006年住房市场面板数据,运用截面固定效应方法对住房价格宏观波动与收入、就业、住房抵押贷款利率、建筑成本等基本经济变量进行定量分析。
In addition, it compares the fixed-effect logistic model, which the empirical results indicate that random-effect logistic model has better early warning effect on the warning veracity and dynamic reflect. 实证结果表明所构建的模型具有较好的拟合效果,并比较了固定效用logistic模型的实证效果,表明所构建的随机效用logistic模型具有更好的预警分类准确性及动态性效果。
