为了研究金融市场中煤炭企业经营管理与收益之间的关系，本文运用时差相关法和PageRank法对a股市场中21家煤炭企业的股票集合进行了领先指数的求取，并对这些股票进行了评分。基于2011年的收益率，揭示了收益率序列的异步性，并呈现了我们股票集的层次结构。最后，我们将实证结果与企业层面的变量进行了比较，并讨论了它们之间的关系。研究结果表明：经营状况良好的大型煤炭企业，其股票收益率往往具有先行性；公司规模与PageRank方法给出的得分呈显著正相关。

英文摘要：
For researching the association between coal enterprise management and return in financial market, this paper applies the method of time difference relevance and PageRank method to seek the leader-index of a stock set containing 21 coal enterprises in A-share market and score those stocks. Based on the return in 2011, the asynchronism of the return series is revealed and presents a hierarchical structure of our stock set. Finally, we compare the result with the firm-level variables and discuss the relation between them. The results show that those large coal enterprises with a good management condition always present an antecedence of stock return; there is a significant positive association between company scale and the score given by PageRank method.
