Accordingly, Marx'critique of political economy must be connected with semeiology and developed to the critique of political economy of the sign.

His Age of Diminished Expectations and Peddling Prosperity filled the gap between the boringly descriptive genre of "up-and-down economics" books and sensationalist and shallow "airport economics" books.

他写的《期望灭失时代》（ Age of Diminished Expectation ）与微弱繁荣的时代，填补了枯燥乏味地描述经济波动的经济学书籍，与标题党式的、浅陋的、在机场出售的经济学书籍之间的鸿沟。

On this basis, according to historical data, apply ANN and differential simulation method to get the quantitatively correlative relations between each production and its own influence factors, and introduce the new methods of prediction for dynamic indexes with gas-field development (The combinatorial prediction method based on fuzzy comprehensive evaluation, the method of ANN to select optimally combinatorial prediction models and the ANN prediction method based on genetic algorithm).(2) Base on mathematical programming, combine with quantitative economics and techno-economics, introduce economical indexes to establish production"s distribution optimal model, production"s constitution optimal model and measured production"s constitution optimal model, including multi-objective models and five-years models. Upon this, the optimal project for all gas field and each gas-collected factory can be got. Also, introduce the time value of capitals to improve on these models.(3) Base on the optimal solution theory and algorithm theory for the nonlinear programming problem, introduce the SUMT algorithm and genetic algorithm to study how to solve the models, and on the basis of normal genetic algorithm, make use of auto-adaptively modulating method to improve on normal genetic algorithm; Base on algorithm"s convergence theory and calculation"s complexity theory to analyze seriatim SUMT algorithm"s convergence and genetic algorithms convergence, and compare performance with each other.

在此基础上，利用神经网络方法和微分模拟方法根据历史数据得到各分项产量与其影响因素之间的定量关联关系，并引入气田开发动态指标新的预测方法(基于模糊综合评判的组合预测方法、神经网络优选组合预测模型预测方法以及基于遗传优化的神经网络预测方法)；(2)以数学规划为基础，结合数量经济学和技术经济学，引入经济指标建立产量分配优化模型、产量构成优化模型、措施产量构成优化模型、气田开发多目标规划模型以及五年规划模型，进而获得全气田及各采气厂的最优方案，并引入资金时间价值对五年规划模型进行改进；(3)以非线性规划问题的最优解及算法理论为基础，引入SUMT算法以及遗传算法对模型的求解进行研究，并在原有的遗传算法基础上，引入自适应调整方法对遗传算法进行改进；以算法的收敛性理论和计算复杂性理论为基础，逐一分析SUMT算法以及遗传算法的收敛性，并比较三种算法的优劣性。

As the evolution of economics, new classical economics has been grown for three stages in natural monopoly, and they are economics of scales, economics of scopes and subadditivity of costs in turn. We review and analyze these thoughts and theories about natural monopoly, and then forecast the trend of natural monopoly theory based on the new institute economics.

本文在对这些理论加以梳理、分析之后，借助新制度经济学的理论和分析工具，预测了自然垄断理论的发展趋势，那就是自然垄断成因由技术成本因素过度到交易成本因素，自然垄断形成机制是在经济学上的自增强机制以及交易成本约束下的一体化理论下完成的，这与先验性的决定自然垄断然后再在行政上加以规制是不同的。

This part makes it clear of the definition of the subjectivism on the economics and the demonstration and status of it.

论文廓清了主观主义在经济学的内涵及其在法律经济学中的表现和地位。

Essentials of Economics is the market leader for the one-semester survey course.

经济学的本质，经济学的本质是一个学期的概况课的市场领导人。

To answer this question, basing on the Economics of Regulation this paper applies path-dependence analysis of the New Institutional Economics and Game Theory, and studies thereinafter contents: 1、The extent of competition the telecommunication industry could realize in technology and practice of some countries in telecommunication deregulation.

为此，本文在规制经济学实证理论的基础上运用制度经济学的路径依赖分析框架和博弈论主要研究了如下内容： 1、电信业在技术上可实现的竞争程度以及各国规制放松的实践。

My conceptual framework relates to the political economy, not the market economy as an abstract construct that is governed by timelessly valid laws.

我的理念结构关系到政治经济学，而不是抽象概念的、受永恒有效规律主宰的市场经济学。

After the demand-supply curve being set up, a partial analysis is drawn into investor behavior with the conclusion that the profit maximizing portfolio is at the point where the investment budget line touches the investment indifference line, or, to be more exact, the topgallant investment bundle for any investor is when any pair of investment assets have the same marginal return.

本文采用现代经济学的分析方法尝试对证券这种虚拟资本进行研究，力求实现证券市场的产品配置与经济学基本问题研究对接的同时，主要在以下几个方面提出了一些自己的见解：证券这种特殊的产品也具有价值和使用价值，证券产品的价值不是真正意义上的价值，而是交换价值；证券产品的使用价值在子能够满足人们投资或投机的需要。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
