This paper studies the cotton futures price index and the spot price of cotton in Zhengzhou Commodity Exchange from June 2004 to September 2010 as samples. By using ADF test, EG method, impulse response, this paper carries out the empirical research on the daily closing data of China's cotton futures market and the spot market. The results suggest that a long-term equilibrium relationship between the spot market and the futures market exists, and that the futures market functions as a guide to the spot market. However, in short-term, the futures market is relatively weak in maintaining the equilibrium relationship. The markets react variously to all kinds of information and are responding more fiercely to the news of decreasing, and this reveals the immaturity of the markets and the existing problems. Based on the research and results above, along with the current situation of China's cotton industry, this paper aims to put forward policy recommendations at the end.","PeriodicalId":127523,"journal":{"name":"2011 International Conference on Business Computing and Global Informatization","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130601959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By introducing Jordan product operator into a finite-dimensional inner product space $V$, we get an Euclidean Jordan algebras $(V, circ)$. For a given $xin V$, we have a spectral decomposition of $x$ with respect to a Jordan frame of $V$. Therefore, we can easily obtain projection of $x$ on the square cone $K$ of $V$($K$ is a symmetric cone). We describe some implementation issues of PC-methods for solving $mbox{SCVI}(K, F)$ with uniformly strong monotone mapping $F$, while $K=R_+^n$, $K=Lambda^n_+$ and $K=S^n_+$, respectively. Finally, we propose an implementation of PC methods for $mbox{SCVI}(S^n_+, F)$ with uniformly strong monotone and Lipschitz continue mapping $F: S^nright arrow S^n$, and give some numerical results to show validity of the proposed method.","PeriodicalId":127523,"journal":{"name":"2011 International Conference on Business Computing and Global Informatization","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125178682","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
