The latest chemical product prices fell, demand has not really visible downstream, the short-term rise in oil prices in the channel, in which phase fluctuations, we continue to be optimistic about with anti-cyclical businesses and new materials, anti-cyclical embodies New Chemical Materials decrease in prices of raw materials is less than the decrease in prices of raw materials at the same time, the cost shift ability, to maintain price stability; civil explosive materials companies fell as a result, prices, countries can enjoy the benefits of; domestic urea production capacity excess of export disruption, high product costs, industry consolidation is inevitable, so concerned about the urea industry with technical advantages and cost advantages of urea enterprises: China Shandong Hengsheng; Although the overall situation of excess nitrogen, but because of the regional characteristics of the domestic fertilizer domestic part of the region will be in a high urea prices, the relevant listed companies will benefit from, such as the Liao Tung Chemical; compound assets as light industry, with the weak cyclical characteristics, the stability of industry profitability, industry leaders concerned about the compound: para Tian shares ; potash by the international market, short-term decline of domestic potash fertilizer prices would have difficulty, Salt Lake Potash in 2009 will be guaranteed a profit, Salt Lake Potash concern.

最新化工产品价格出现下跌，可见下游需求并未真正起来，短期石油价格处在上升通道，在这种上下波动阶段，我们继续看好具有抗周期性的新材料企业，抗周期性体现了化工新材料的产品价格下降幅度小于原料的下降幅度，在原料价格上涨同时，成本转嫁能力较强，价格维持稳定；民爆企业由于原料下跌，价格上涨，可以享受国家指导价的益处；由于国内尿素产能过剩，出口受阻，产品成本居高不下，行业整合在所难免，因而关注尿素行业内具有技术优势和成本优势的尿素企业：华鲁恒升；虽然氮肥全局过剩，但由于国内化肥的区域性特征，国内部分区域尿素价格将处于高位，相关上市公司将因此受益，如辽通化工；复混肥作为轻资产行业，具有弱周期性特点，行业盈利稳定，关注复混肥行业龙头：芭田股份；钾肥受制于国际市场，短期内国内钾肥价格恐难下跌，09年盐湖钾肥盈利将会有保证，关注盐湖钾肥。

In the analysis frame about house market and land market, this research has set up a simultaneous equation model of urban house prices and land prices in China. Collecting 35 major metropolitans database from 2003 to 2005 and using two stages least squares method, this research analyzes the endogenous and exogenous determinants which have caused the inter-metropolitan variation in the house prices and land prices in China.

We introduce convex,and in particular semidefinite,optimization methods,duality and complexity theory to shed new light to this relation for the single stock problem, given moments of the prices of the underlying assets,we show that we can find best possible bounds on option prices with general payoff funcations efficiently,either algorithmically(solving a semidefinite optimization problem)or in closed form, conversely,given observable option prices,we provide best possible bounds on moments of the prices of the underlying assets,as well as on the prices of the other options on the same asset by sovling linear optimization problems for options that are affected by multiple stocks either directly(the payoff of the option depends on multiple stocks)or indirectly(we have information on correlations between stock prices),we find on-optimal bounds using convex optimization methods,however,we show that it is NP-hard to find best possible bounds in multiple dimensions,we extend our results to incorporate transactions costs,this paper,in theory and practice can provide a reference to researchers and designers about Chinese financial derivative products,the full text is divided into six chapters as follows: ChapterⅠ:Papers on the background and significance of the subjects on a number of option pricing models as well as their advantages and shortcomings of the model and describes the status of research and writing papers and the main contents of the basic idea.

相应地，给定期权价格，也能够出标的资产瞬时价格的最有可能的最好的界。还有通过解决一个线性最优化问题，根据同一标的资产的其他期权的价格来找到这个期权的界值，对于期权受到多种股票价格直接影响(期权的收益依赖于多种股票)或者间接影响(我们有股票之间联系的有用信息)，如果使用凸规划方法我们就会发现没有最优的界，也能够证明对于多维情形确实是很难找到最优的最有可能的界值，最后将这一结论推广到考虑交易成本的情况。本文在理论和实践上给我国金融衍生产品研究者和设计者提供一定的参考。全文共分为六章，具体安排如下：第一章：阐述论文的选题背景和意义，介绍期权定价的一些模型以及这些模型的优点与缺点，并介绍国内外研究的现状以及论文的写作基本思路与主要内容。
