Economics and underdetermination: a case study of urban land and housing economics

Underdetermination, associated with the Duhem–Quine thesis,is a familiar if under-researched theme in economics. In thelight of this, we examine the development of urban land andhousing economics. Through its Cartesian dualistic delineationof theory and data, the contemporary mainstream approach appearsunable to circumvent the problem of underdetermination. In effect,it employs the strong version of Duhem–Quine in its retentionof the assumption of a single, unitary competitive market (andassociated access–space trade-off). Conversely, we highlightthe affinity of Ely's (and the later Columbia School's) approachto pragmatists Dewey and Peirce, which provides a more fruitfulbasis for explanation.     

Multilateral Comparison of Cost Structures in the Input–Output Tables of Japan,the US and West Germany

This paper presents a multilateral comparison of relative levels and structures of costs of production in Japan, the US and West Germany. The analysis is carried out by using harmonized input–output tables, which are converted at US prices by using adjusted sectoral purchasing power parities. A new accounting methodology is derived from recent developments of index number theory, whereas the chosen multilateral comparison procedure gives results that are invariant with respect to the order of the pairs of countries examined.     

信息技术在工程建设领域中应用的发展趋势--信息孤岛与信息集成

详细分析了国际上信息技术在工程建设领域中应用的发展趋势，主要包括三个方面的内容：首先是介绍信息技术在工程建设领域中应用的信息孤岛现象，然后引进并阐述总体项目系统的概念，最后则描述了基于信息模型的集成和基于Internet的集成等两种解决思路。     

Polyhedral Combinatorics in Combinatorial Optimization

Polyhedral combinatorics is a subarea of combinatorial optimization of increasing practical importance. It deals with the application of the theory of linear systems and linear algebra to combinatorial problems. The paper is not intended as a survey on polyhedral combinatorics but it reviews some of the main concepts and proof techniques.     

西方城市化理论二元结构分析框架:一个文献综述

在发展经济学中，西方城市化理论可以被划分为两类：一是从经济结构转换的视角研究人口流动的二元经济结构理论；二是从区域发展的视角研究空间过程的二元区域结构理论。将两者结合起来对其进行文献综述。

重庆经济结构存在的矛盾与对策

重庆市与西部的多数省区一样,经济发展面临着特有的结构性难题,主要包括三次产业结构矛盾、工业内部结构矛盾、区域经济结构矛盾和城乡"二元经济"结构矛盾等.应尽快优化、提升产业结构,并努力实现区域经济、城乡经济的协调、健康发展.     

加快重庆新型工业化进程的思考

重庆工业化具有跳跃式发展的基本特征，导致了其工业化与城市化进程分离，形成了明显的二元经济结构。重庆应按照新型工业化道路要求，加快工业结构的战略调整，加快农村工业化、城镇化步伐，消除二元经济结构，并大力推进工业增长方式转变．提高工业科技水平。     

数字经济对我国碳排放的影响研究

基于2013-2020年的30个省份数据构建面板数据模型,从碳排放总量和碳排放强度两个视角研究数字经济发展对区域碳排放的影响。研究发现：数字经济的发展有效地降低了人均碳排放量、碳排放增量与碳排放增速,数字经济与碳排放强度之间存在倒“U”形关系,数字经济与碳排放强度、边际碳排放强度的关系呈现区域性特征,在省域层面数字经济对边际碳排放强度的影响不存在明显的空间效应,数字经济对碳排放增长率的影响存在基于产业结构优化、人口集聚、城镇化的遮掩效应。
