苏南地区被撤并乡镇驻地再利用研究——以南京市六合区为例

自20世纪90年代起苏南地区在全国率先启动了以乡镇合并、村庄撤并为主要内容的村镇区划整合工作,有力地推动了该地区乡村的集聚发展,但是也逐步带来一些新的问题,特别是已撤并乡镇驻地缺乏科学合理的再利用,在一定程度上制约了乡镇合并的集约效果。在回顾比较苏南地区村镇区划整合的效果基础上,从新型城市化下城乡统筹和建设新型乡村社区的要求出发,分析被撤并乡镇驻地后续发展建设存在的问题,从均等化与集约化相结合的要求出发,提出该地区被撤并乡镇合理再利用的基本方向。以南京市六合区为例,对被撤并乡镇驻地合理再利用的模式进行了探讨。     

Merging time‐series Australian data across databases: challenges and solutions

This study discusses the differences in company identification across sources of Australian data and raises important issues which should be considered prior to merging across databases. In particular, we show that the practice among accounting databases of overwriting prior identifiers used by a given company, with its most recent, results in failure to match data which actually exists. We suggest a method for reconciling these differences and show that our method results in a match rate of 97 percent with the Aspect company identification file, and 94 percent after missing accounting data is considered. This contrasts with a match rate of only 71 percent when performing a direct merge.     

以制度创新推动B股市场改革

B股市场问题是我国资本市场发展过程中的一个遗留问题,B股市场问题的解决对我国资本市场的规范化和国际化发展具有重要意义。本文认为,B股市场问题根源于一系列制度缺陷与制度变迁,与A股市场并轨是解决B股问题的现实的最佳选择,在此基础上,本文就通过制度创新实现A、B股市场并轨进行了分析思考。

Proportional scheduling, split-proofness, and merge-proofness

If shortest (respectively longest) jobs are served first, splitting a job into smaller jobs (respectively merging several jobs) can reduce the actual wait. Any deterministic protocol is vulnerable to strategic splitting and/or merging. This is not true if scheduling is random, and users care only about expected wait.The Proportional rule draws the job served last with probabilities proportional to size, then repeats among the remaining jobs. It is immune to splitting and merging. Among split-proof protocols constructed in this recursive way, it is characterized by either one of three properties: job sizes and delays are co-monotonic; total delay is at most twice optimal delay; the worst (expected) delay of any job is at most twice the smallest feasible worst delay. A similar result holds within the family of separable rules,     

Stakeholders’ perception of defragmentation of new plots in a land consolidation project: Given the surprisingly different Slovak and Czech approaches

There is a fundamental difference in the way of merging the fragmented plots of one owner within a land consolidation (LC) in Slovakia (the Slovak Republic, SK) and the Czech Republic (CZ). All the scattered shares of a single owner in SK are merged into a minimum amount of new plots in the proportion of 1/1; the shares of one owner in CZ are merged only to a group of owners who are on the same ownership title.Through an LC project a Slovak owner automatically acquires sole ownership and the Czech one remains in an unchanged ownership in equal shares. Authors wondered what general public and the owners themselves in particular think of these two ways of merging. A simple online questionnaire for all surveyed groups (representatives of owners, public administration officials, LC designers/experts) for a virtual model territory was created. The results based on the questionnaire (563 responses, 10–25% estimated rate of return, were evaluated at the time of preparing the contribution) show that there is a clear preference (90–98%, estimated margin of error 5–16%) for the exclusive ownership. The (surprising) differences in merging as well as subsequent findings provoked an informed debate about the causes which is still pending.     

西方主流经济学对企业并购动机的综述

很多经济学派对并购现象的产生都进行了解释。但企业并购的动机迄今为止还无法形成一个系统的理论框架。而事实上，不同的购并活动背后的动机常常无法用单一的理论来解释。并购的经济实践不会停止，与此相应的是对企业并购动机进行研究的理论也会随着并购实践的发展而深入。     

城市竞争的效应分析

资源的稀缺性决定了市场主体必然为获取其发展所需的经济资源而展开竞争。城市作为资源的空间和时间集聚载体，也必然面临相互间的竞争。城市竞争的结果会相应产生集聚效应、扩散效应和融合效应。     

国防科技产业军民深度融合模式与路径研究

军民融合式发展是促进国防科技产业快速发展和统筹国防建设与经济建设协调发展的必由之路,国防科技产业是军民深度融合的最佳载体和重要平台。将国防科技产业领域军民融合发展归纳为院所自转、军工自转、院企联转、校企联转、军民共转、民企参军等6种模式,在此基础上,从技术、资本、人才、制度、组织、市场、产业链等7个方面探索相应的军民深度融合路径,以期为形成军民深度融合发展格局提供有益借鉴。
