从“其他绿地”到“区域绿地”： 城市非建设用地下的绿地规划转型 与优化

新版《城市绿地分类标准》(CJJ/T 85—2017)以“区域绿地”代替“其他绿地”，这为城市非建设用地下绿地的保护利用提出了新的要求和目标。解读新标准指导下城市非建设用地中的绿地建设发展要求并进行科学合理的规划，是响应当前城市绿色发展新形势和满足人民日益增长的美好生活新需求所面临的重要课题之一。聚焦从“其他绿地”到“区域绿地”的分类调整，分析新标准下区域绿地的内涵和特征。以河北省承德市为例，结合城乡发展需求，阐述区域绿地规划的核心转型思路。并从目标、内容、方法和评价等方面，论述区域绿地设定下城市非建设用地中绿地规划的具体内容和方向。最后从空间政策、发展引导、部门合作和大众参与等方面，提出了规划实施保障优化的策略。以“区域绿地”的解读为源，聚焦当前城市建设用地内外绿地规划建设割裂的现状问题，提出区域绿地规划的转型优化措施和实践经验，以期为新时代中国城市绿色空间的拓展与优化提供参考。     

关于高校创造性教育的思考

创造性教育是高等教育的重要任务和目标。高校创造性教育的基础是心理健康教育。创造性教育与心理健康教育是相互作用、相互促进的互动关系；高校创造性教育的关键是个性教育。个性教育的最终目标是发展学生的创造力，使之成为创造型的人才；高校创造性教育的途径是教学活动。创造性人才的培养，有赖于学校创造性的教育，而学校实施教育的途径是教学。

Intraday Empirical Analysis and Modeling of Diversified World Stock Indices

This paper proposes an approach to the intraday analysis of diversified world stock accumulation indices. The growth optimal portfolio (GOP) is used as reference unit or benchmark in a continuous financial market model. Diversified portfolios, covering the world stock market, are constructed and shown to approximate the GOP, providing the basis for a range of financial applications. The normalized GOP is modeled as a time transformed square root process of dimension four. Its dynamics are empirically verified for several world stock indices. Furthermore, the evolution of the transformed time is modeled as the integral over a rapidly evolving mean-reverting market activity process with deterministic volatility. The empirical findings suggest a rather simple and robust model for a world stock index that reflects the historical evolution, by using only a few readily observable parameters.

Diversification Strategies and Corporate Coherence Evidence from Italian Leading Firms

This paper investigates the determinants of coherence and coherence change usinga sample of Italian leading firms in the period 1993–1996. Consistently with thehypotheses advanced by Teece et al. (1994), the econometric analysis highlightsthat relatedness between pairs of sectors and coherence of diversification strategiesare higher when firms are active in sectors sharing similar technological and marketingcharacteristics, and when they are positioned at different stages of the productive chain.Moreover, the findings that firms which enter the group of top 5 industry leaders aremore coherent than the average and that coherence is increasing for firms active insectors more sensitive to EU integration are consistent with the prediction that coherentfirms tend to outperform less coherent ones and that coherence is increasing in morecompetitive environments. Finally, the results show that a deepening of vertical integration strategies is good for coherence change, while an increase of diversification brings a reduction in coherence.     

企业多元化的新模式：基于核心能力的虚拟经营

本文研究了企业多元化经营的科学含义，创建了一个二元作用定性模型来论证企业发展到一定阶段多元化经营的必然性，研究了现代企业虚拟经营的背景，含义以及企业深化，培育核心能力与开展虚拟经营之间的本质联系，考察了多元化成功与失败的众多企业案例，当代多元化经营成功的企业大多是基于核心能力的战略相关多元化，而虚拟经营也是核心能力培育，深化的产物，借助于基于核心能力的虚拟经营以实现相关多元化发展，是企业多元化的一条新途径，相对于传统多元化而言，它更具竞争优势。     

Diversification, Ownership and Control of Swedish Corporations

We study the short‐ and long‐term valuation effects of Swedish takeovers. Using a sample of 93 bidding firms that acquired 101 targets between 1980 and 1995, we find that diversifying acquisitions lead to a negative market reaction and deterioration of the operating performance of the bidder. Announcement and performance gains in each of the three years following the acquisition occur only when bidders expand their core rather than their peripheral lines of business. Our findings suggest that focused acquisitions lead to greater synergies and operating efficiencies than diversifying acquisitions. Intra‐group acquisitions, however, show that bidders do not realise significant gains whether they adopt diversifying or focusing investment strategies by purchasing firms controlled by the Wallenberg and SHB conglomerate groups. Intra‐group targets realize significant gains regardless bidder's investment strategy. Finally, the evidence does not support the view that intra‐conglomerate acquisitions are associated with expropriation of minority shareholders. However, they appear to enhance the control rights of large shareholders of the bidding firm.     

中国乡村城市化浅析

实现乡村城市化是我国21世纪实现工业化、现代化重要战略布置，也是我国经济社会发展面临一项十分紧迫的任务。正如马克思在《政治经济学批判》中指出：“现代的历史是乡村城市化，而象古代那样，是城市乡村化。”因此，寻求一条适合我国国情和地区特征乡村城市化道路，探索我国乡村城市化发展的战略思想，是当代城市规划工作面临的一个严峻课题，也是制定跨世纪城市规划的重要组成部分。
