Discovering the influences of the patent innovations on the stock market

With the implementation of the innovation-driven development strategy, increasing technical innovations are patented by the individuals or the companies. As a form of intellectual properties, the patent has attracted attention from individuals and companies. Although there are some researches on the economic function of patent, few quantitative researches discuss on whether patents can work on the company stock market. To discover the relations between the company patents and the stock market, we explore a method to analyze the influence of patent activity on the company stock market. We collect the patent data and the stock data of listed companies, from which patent and market activities are extracted. By the recursive discrete wavelet transform, the patent and market activities are decomposed into multi-scale wavelets. These wavelets are fed into a patent and market activity based stock market trend prediction model, in which the influences of patent activity are analyzed. We compare our model with the state-of-the-art model on 4 measurements for 3 manufacturing datasets. The experimental results show that the patent activities have positive effect on market trend prediction in about 30% manufacturing listed companies and that the measurements of Shanghai/Shenzhen Stock Exchange often outperform that of USA in years 2016–2019 for the manufacturing listed companies.

关于我国外汇市场主要汇率的协整分析

自1973年布雷顿森林体系崩溃以来，世界外汇市场的汇率就表现出巨幅而且频繁波动的特征。由于外汇市场风险极大，因而要捕捉到汇率运动的规律就十分困难。目前，几家中国的商业银行推出了个人外汇买卖业务。本文着重对几种汇率之间的协整关系进行实证分析，以期发现它们之间是否存在长期的稳定的关系。其结果将有助于投资者制定决策并且有效地规避风险。

Inclusive work at a European level: a case study

In this article, Paul Stephenson and Glynis Rumley describe the way in which educators in Kent have developed strong links with their colleagues and neighbours from Nord Pas de Calais in France. From a variety of projects undertaken, some of which were assisted by funding from European sources, children of all abilities and needs have been able to work and learn together. The PILOTE programme, developed in Kent by the local education authority's Modern Foreign Languages (MFL) team, has been used to overcome language barriers and, by making learning fun, has enabled both adults and children alike to communicate with each other during the project work which has been undertaken. From a strong emphasis upon enjoyment and within a natural context for learning, teachers with little previous foreign language experience have been empowered to enhance their children's language skills. The approaches used have been relevant both to children in the mainstream situation as well as those in specialist provisions. The ‘Above and Beyond Barriers’ projects have enabled children to find out more about their European counterparts and communicate with them in a meaningful and enjoyable way.
