本文将经济集聚效应、劳动力流动和房价纳入同一研究框架,研究在经济集聚效应下劳动力流入对房价的空间溢出效应,利用计量统计方法取得如下研究结论:地方经济的集聚吸引劳动力的流入;劳动力流入对流入地房价呈倒U型影响,在供需关系下,... 本文将经济集聚效应、劳动力流动和房价纳入同一研究框架,研究在经济集聚效应下劳动力流入对房价的空间溢出效应,利用计量统计方法取得如下研究结论:地方经济的集聚吸引劳动力的流入;劳动力流入对流入地房价呈倒U型影响,在供需关系下,劳动力流入拉高当地房价,但超过一定程度时会对当地房价产生负向影响;在经济集聚的情况下,劳动力流入对房价的倒U型关系源于房价的空间溢出效应,即流入超过当地承载量时,劳动力的居住选择向城市外扩展,抬高周围地区的房价,缩小地区间相对房价差异。 展开更多

This article used the Cluster analysis of statistical method to separate China's 30 provinces and municipalities into three categories according to their energy consumption discrepancies and characteristics from 1985 to 2007. The categories were high, moderate and low energy consumption areas and they had significant differences in energy consumption. Based on this classification, the authors analyzed the influencing factors of energy consumption in the three areas by means of panel data econometric model. The results showed that the influencing factors were obviously different. In order to support national goal of energy conservation and emission reduction, the energy measures and policies should be distinctly taken. 展开更多

Saturated row-column designs are studied to eliminate positional effects in primary high- throughput screening experiments. Compared to designs currently used in practice, all compounds in the designs considered are comparable within each microplate in spite of the existence of row and column effects. The designs considered in this paper also have the maximum number of compounds arranged in each microplate. Two statistical methods are used to choose leading compounds in the designs considered. These two methods take full advantages of effect sparsity in primary screening. Simulation studies are carried out to compare the two statistical methods with two ad hoc methods in selecting active compounds. A method that maintains balanced false positives and false negatives is recommended. 展开更多
