Power spectrum analysis and statistical moment function on a range of scales revealed scaling qualities of the date from stock market.

Assuming that both the soft component and the hard component obey KNO scaling in the multiplicity distribution of high energy hadron-hadron collision but their respective parameters are different, the multiplicity distriblltion of the charged particle in P collision at=1800GeV is calculated.

After giving comparison of the current related economic thought on clustering, the paper gives an explanation for the formation and evolution of the clustering of the industrial organizations with its scale-free property using systematic analytical methods and mathemati.

In order to quantificationally characterize the scale-free feature of corporate governance structure,this paper first proposes and defines the concept of corporate governance structure entropy,and explains two states of corporate governance including the manager control and the shared governance in terms of corporate governance structure entropy.

On the bases of scaling of stock fluctuation and detrended fluctuation analysis (DFA) the application is researched,the scaling aniorrelation of the index of the Shanghai stock Market,Shenzhen stock Market and Dongdaapai in china,and we analysed practically calculated the DNA walk disptecement,the volatility and scaling ancorr.
