城市规划的政策属性

通过对相关文献的解读,认为我国对城市规划政策属性的认识随着社会发展在不断深化,可以分为三个阶段。基于城市规划作为公共政策的定位,从多个视角对城市规划的政策属性展开研究,认为城市规划要真正实现向公共政策的转型,关键是按照公共政策的属性,重新系统地建构城市规划学科知识体系,尤其是要将城市规划纳入整个社会系统,进行制度创新。

Identification of approximately duplicate material records in ERP systems

The quality of master data is crucial for the accurate functioning of the various modules of an enterprise resource planning (ERP) system. This study addresses specific data problems arising from the generation of approximately duplicate material records in ERP databases. Such problems are mainly due to the firm’s lack of unique and global identifiers for the material records, and to the arbitrary assignment of alternative names for the same material by various users. Traditional duplicate detection methods are ineffective in identifying such approximately duplicate material records because these methods typically rely on string comparisons of each field. To address this problem, a machine learning-based framework is developed to recognise semantic similarity between strings and to further identify and reunify approximately duplicate material records – a process referred to as de-duplication in this article. First, the keywords of the material records are extracted to form vectors of discriminating words. Second, a machine learning method using a probabilistic neural network is applied to determine the semantic similarity between these material records. The approach was evaluated using data from a real case study. The test results indicate that the proposed method outperforms traditional algorithms in identifying approximately duplicate material records.     

From a System of National Accounts to a Process of National Wellbeing Accounting

There are repeated calls to go ‘Beyond GDP’, for measures of wellbeing and progress in addition to those that the System of National Accounts (SNA) is designed to provide. We identify key issues that can help build on the rigour of SNA whilst fitting the measurement of economic performance within a broader assessment of national wellbeing and progress. Such drivers are already leading to a proliferation of indicators and accounts, for example in the development of non‐monetary measures of natural resources, but there are significant measurement challenges, not least the question of whether a single, overall measure or index of wellbeing is valid. But the challenge of measurement, per se, is one thing: in our view, a more critical issue is whether the measures will actually be used. We propose a dynamic and multi‐staged approach for developing SNA, embracing the production and use of measures. This would start by identifying user requirements for wider measures, to provide the basis for national and cross‐national developments in well‐being accounting. We envisage greater branding and marketing of national well‐being concepts to promote measures and support their use. We call for outreach by producers, so that there is dialogue about the development and use of measures.

我国空间规划体系的时代困境与模式重构

我国现行的空间规划体系成形于计划经济时期,虽伴随国家公共政策的变化经过多次调整,但规划体系仍不完善,规划的运行也出现了诸多问题,不仅降低了规划的有效性,并且浪费了大量运行成本。空间规划是协调人地关系和促进区域发展的重要手段,在实践中必须实现规划行政体系整合、规划编制体系整合和规划法规体系整合。本文提出了整合模式的初步设想,试图为空间规划体系的改革提供参考。     

城乡规划法的价值演进

城乡规划法本质上与时空发展的状况具有耦合性,其范式是不断演进的.2008版城乡规划法是新时空精神的升华,内容框架和价值取向都有较大的创新.该法体现了利益主体的多元化,表现了从"计划"到"市场"的转型,反映了空间上的城乡统筹导向以及策略上的公共政策属性.同时,2008版城乡规划法在规划协作、规划体系等方面所存在的一系列问题,需要在实践中不断地解决和修正.     

完全信息动态条件下企业总成本领先战略探究

首先,从迈克尔.波特教授的著作中引入总成本领先战略;接着,从博弈论斯坦克尔伯格模型出发,来建立所要分析问题的一般化模型,并分析一般化的完全信息动态模型得到均衡解。在结论分析中,引入要讨论的总成本领先战略,通过对比分析先动的企业和跟随的企业在采取成本领先的时候其市场的份额和利润,得到讨论的结论;先动的企业采取成本领先可以获得行业竞争优势,跟随企业在采取足够低的成本领先的前提下,也可以获得更高的市场份额和利润空间,从而可以获得竞争优势。
