基于共生关系的创意产业集群形成机制——上海18个创意产业集群实证

以上海18个创意产业集群为分析对象,利用共生模型对创意产业集群之间的形成机制进行实证研究。研究结果表明,互利共生关系是创意产业集群形成的逻辑起点,互利共生关系越贴近于对称互利共生关系,则创意产业集群效应越好,从而越有利于创意产业集群的形成和稳定发展,且共生关系质量越好。

Was there a Portfolio Effect of the Micro-economic Leverage ？ Some Empirical Evidence from the Chinese Stock Market

The study is on a linear model of the relationship between the systematic risk and the micro-economic leverage and analyzed the data from the steel, energy source and chemical fibre industry listed companies in the Chinese stock market in 2002 and 2001. Using the linear regression method, empirical equations were found. The portfolio effect was shown so that some empirical evidence had been found to support the micro-economic leverage portfolio effect theory, which was that the listed companies balanced the operating and financial leverage to minimize the systematic risk.     

浅谈区域可持续发展的静态评估指标体系构建

Time variation in the cointegrating relationship between stock prices and economic activity

The present paper examines whether there exists a long‐run cointegrating relationship between a stock market index and output and interest rates. Moreover, estimation is conducted over the full sample and both a recursive and rolling sample to examine any time variation in the nature of the relationship. The results support evidence of a single cointegrating vector, where stock prices typically exhibit a positive relationship with industrial production and a negative relationship with interest rates. However, there is significant time variation and periods of time where contrary results are observed. As such any model of stock prices needs to account for such time variation
