Methods of measuring the input components, their prices and output elements are given. We put forward some new methods in measuring components, including composite depreciation rate, equality working hours, and proxy of input resources. Using the mature methods of efficiency measurement and decomposition available, we make a detailed investigation into 4 listing companies of oil industry with a span of 12 periods. Basic conclusions we draw include: labor inputs affects oil field output mostly in China; China oil fields operates in a low technical efficiency level average of 0.61; Increasing difficulties with expanding output has the greatest influence on cost; Cost efficiency of China oil fields averages at 1.47; Total factor productivity of China oil fields averages at 10%, accounting for 79% of the total output growth rate of 12.6%; Frontier technology progress contributes the most to TFP of China oil fields with 17 percentage points.

本文沿用了已有文献中关于效率计量与分解的成熟方法，对我国三家油田上市公司与一家上市石油公司12个时期的技术效率与成本效率进行了详细的计量、分解与分析，得到的基本结论有：劳动力投入是影响我国油田上市公司产出的最重要的影响因素；油田的平均技术效率仅为0.61；产出项是影响成本的显著因素，这说明随着产出增加而出现的开采难度增加是导致开采成本增加的重要因素；油田的平均成本效率为1.47；全要素生产率的增长平均在10％左右，占到了产出平均增长率12.6％的79％，表明我国油田的生产率的提高主要是依靠全要素生产率的提高而实现的，只有21％左右的产出增长是依靠要素投入而实现的；前沿技术进步是油田全要素生产率增长的主要源泉，在2001～2004年期间，前沿技术进步对油田生产率的贡献高达17个百分点。

The major findings include:(1) By using fuel as the base indicator of relative efficiency, we found the following input factors' distribution inefficiency for domestic airlines: The distribution inefficiency of labor and capital input factors differs from airline to airline, and is becoming more severe with time; the distribution inefficiency of other factors does not differ very much among airlines but varies with time. It is inefficient from 1989 to 1995 but becomes more efficient during 1996 to 1997;(2) Airline companies have higher economies of density before 1996, but tend to show a constant return to density in 1997 when considering allocative distortions. The technical efficiency of input factors as a whole has declined after the open-air policy;(3) The costs of airlines are increasing significantly due to their distribution inefficiencies;(4) The instrument variable generated through a quasi price function does not have significant influence on cost; this may imply that airline companies in this time period did not exhibit the phenomena of high-quality high-price.

其主要结论如下：(1)藉由相对燃油分配效率探讨各投入要素之分配扭曲情形发现：劳动和因定投入要素之分配无效率因公司别而有所不同，且随时间而严重，唯民国86年稍有改善；其他要素之分配无效率则较不因公司别而有所不同，但亦随时间发生变化，初期为无效率，在民国85、86年则较具效率；(2)若考虑分配扭曲情形下，国内航空业在民国85年之前具有较高之密度经济，民国86年则趋向固定密度报酬；此整体投入要素之技术效率而官，在天空开放政策后其技术效率随时间变化而下降，但就燃油投入要素平均技术进步率而言，则其技术效率逐年增加且幅度明显；(3)航空公司因分配无效率所造成成本增加的情形相当明显；(4)准价格工具变数对成本之影响并不明显，此可能反映在此期间国内航空公司似乎并未趋向於高品质高价格之现象。

The economic growth accounting of China's provinces between 1990 and 2004 finds some results like the following: no matter whether human capital was introduced or not, there were technological inefficiencies in most provinces'economic activity which were pure technological inefficiencies or scale technological inefficiencies; technological change, capital deepening and human capital accumulating all promoted labor productivity, but technological efficiency change played a negative role during these years as a whole; the descending order of provincial difference of labor productivities'changes brought out by each factor was technological change, capital deepening, technological efficiency change and human capital accumulating; each province's pure technological efficiency change or scale efficiency change not only had different size, but also different evolution route.

中国各省在1990～2004年间的经济增长核算结果表明：不论是否引入人力资本，大多数省份的经济活动都存在着技术无效率，这既包括纯技术无效率，也包括规模无效率；技术进步、资本深化和人力资本积累都促进了劳动生产率的提高，而技术效率的变化整体上来说在其中起阻碍作用；各因子引致的劳动生产率变化的省际差异从大到小依次为技术进步、资本深化、技术效率的变化和人力资本积累；各省的纯技术效率或规模效率的变化不仅大小不同，而且它们的演变路径也不一样。

进而，本文采集中国上市公司数据，验证本文提出的有限理性对公司定价的影响机理，实证研究发现：1、中国证券市场上，投资者不能正确判断公司价值创造的效率，从而中国上市公司的市场价值严重脱离公司价值创造的实际情况，出现公司价值创造效率越低，市场对公司的价值预期反而越高的现象。2、背离了公司真实价值创造效率的市场对公司的价值预期强烈影响到公司经理人的投融资和经营行为，阻碍了公司下期的价值创造效率。3、在公司定价偏差对公司内在价值的反作用过程中，行为成本、代理成本和制度成本使经理人理性在现实中受到限制，从而经理人的有限理性行为妨碍并降低公司再投资效率，进而妨碍了公司价值创造效率，从而影响公司的内在价值和市场价值。

The second part is the second chapter of the paper, is introduces efficiency measurement methods and theory on banking, make matting for efficiency of the Rural Credit Unions.
