本文在Houghton总结出的不同勘探阶段七种储量分布曲线类型基础上 ,根据截断帕雷托分布模型 ,对松辽盆地北部未发现气田储量规模分布和总储量进行了预测 ,并且又应用分形方法预测了未发现气田总储量。结果表明 ,截断帕雷托分布模型与分形方法预测的未发现气田储量大小相吻合 ,验证了TSP分布模型是预测油气田储量的可靠方法。最后得出以下主要结论 :TSP分布模型预测油气资源分布受具体盆地地质条件影响较小 ,具有推广价值 ;TSP分布模型与其它资源评价方法相比 ,预测的油气储量还不很完善。

A Bayesian approach using Markov chain Monte Carlo algorithms has been developed to analyze Smith’s discretized version of the discovery process model. It avoids the problems involved in the maximum likelihood method by effectively making use of the information from the prior distribution and that from the discovery sequence according to posterior probabilities. All statistical inferences about the parameters of the model and total resources can be quantified by drawing samples directly from the joint posterior distribution. In addition, statistical errors of the samples can be easily assessed and the convergence properties can be monitored during the sampling. Because the information contained in a discovery sequence is not enough to estimate all parameters, especially the number of fields, geologically justified prior information is crucial to the estimation. The Bayesian approach allows the analyst to specify his subjective estimates of the required parameters and his degree of uncertainty about the estimates in a clearly identified fashion throughout the analysis. As an example, this approach is applied to the same data of the North Sea on which Smith demonstrated his maximum likelihood method. For this case, the Bayesian approach has really improved the overly pessimistic results and downward bias of the maximum likelihood procedure.

当前,我国经济正在从高速增长阶段转变为高质量发展阶段。区域经济发展离不开金融支持,京津冀制造业转型升级也需要金融支持。选取2010-2020年京津冀面板数据,采用熵值法和面板回归法实证分析金融支持京津冀制造业高质量发展的效果。结果显示:金融规模能够显著促进京津冀制造业高质量发展,金融效率对制造业高质量发展具有负向影响。此外京津冀制造业高质量发展水平与直接融资占比呈正相关,而与中长期贷款占比呈负相关,说明目前京津冀制造业高质量发展的金融需求并没有得到充分满足。结果结论有助于提高京津冀地区的金融支持水平,为推动该地区先进制造业的发展提供参考。
