Order Aggressiveness in Shanghai Stock Market of China

This paper analyzes order aggressiveness in Shanghai stock market of China which is a pure order driven market. We provide empirical evidence that the mean order aggressiveness is negative （low） and most traders are liquidity providers. Our results also show that high order aggressiveness accompanied with high market volatility and large trade volume. The intraday order aggressiveness pattern is from low to high. Four factors： spread, volatility, order imbalance and size affect order aggressiveness, but they affect the buy and sell side differently.     

Demonstration Study on the Intrinsic Characteristic of Stock Complex Index on Shanghai Security Market

This paper takes the Shanghai Security market stock composite index as the research object, analyzes its intrinsic fractal essence characteristics by the application of fractal theory and the method, and computes the Hurst index, fractal dimension and correlated function of the highest prices of the complex index. Moreover, it studies characteristics of long term memory of the sample data and its variance along with time; study existence of chaotic attractors in data of the complex index by reconstructing the phase space of the index data. Finally, this paper carries on the related forecast demonstration study to the stock composite index. Results of the study have certain reference function to the actual problem.

Remote sensing of spatial patterns of urban renewal using linear spectral mixture analysis: A case of central urban area of Shanghai (1997―2000)

It is very important to integrate remote sensing with urban geography that the spectral mixture analysis technique is applied to urban land cover evolvement and its eco-environmental effect. Urban land cover is mainly composed of complicated artificial materials, which is the key factor to limit the development of the spectral mixture analysis technique. There are two main aspects in which the technique of spectral mixture analysis is applied to urban geography： one is to calculate vegetation fraction; the other is to build quantitative model of the urban impervious surface obtained from the combination between high albedo fraction and low albedo fraction. The technique of spectral mixture analysis is firstly applied to study urban renewal pattern, scale and mode which happened in Shanghai City from 1997 to 2000,

杨小舟蛾在上海地区的发生规律及其预测预报

对杨小舟蛾在上海的生活史和发生规律进行了研究。结果表明:杨小舟蛾在上海1年发生5代,个别有6代现象,世代重叠严重。杨小舟蛾的发生与初始虫量、日平均温度、降水量、日平均湿度呈极显著正相关。当日平均气温15℃以上时,杨小舟蛾开始出现;日平均温度在25~30℃时,杨小舟蛾数量明显增加;当湿度为65%~85%的时候,该虫发生集中,在日相对平均湿度为80%时,成虫的数量急剧增加;在日平均降雨量为50~150 mm时,虫口数量比较集中。建立杨小舟蛾短期测报模型为:Y=-101.909-0.091x1 0.155x2 0.338x3 0.659x4 0.539x5。
