评国有企业改制“靓女先嫁”模式——从香港太古整体收购厦门绿泉说起

本文作者从2006年9月10日香港太古集团整体购并厦门绿泉实业有限公司这一案例谈起,讨论了国有企业改制“靓女先嫁”模式中存在的问题。作者认为,应从国有资产价值的客观评估、通过立法规范国有企业改制的“靓女先嫁”模式、设立并购安全港指标等方面着手来解决这些问题。The Swire Pacific Limited of Hongkong merged the Lvquan Enterprise of Xiamen on Sep. 10th, 2006. From this merging case, the author of this article discussed some problems exist in during the process of transition of State-owned Enterprise. The author thinks, in order to solve these problems, we should evaluate state-owned capital fairly and properly, standardize the mode of Marry First the Beautiful Girl under related law or regulations, and adopt safe-port index as the U. S. A for seek of probably monopolization when merging happened

Factor Input and Urban Economic Growth in China

建国以来尤其是改革开放以来我国城市经济获得了巨大的发展。但由于缺乏对各要素在我国城市经济增长过程中的作用机制与贡献度的研究，导致近年来我国各城市在制定政策促进经济增长时不能取得预期的良好效果。因此，对我国城市经济增长过程中各要素的供求机制、各要素间的作用机制以及在要素作用下城市经济增长机制的研究，对我国城市经济增长中各要素的贡献、要素利用效率的分析，有利于我国城市政府采取政策措施促进适合本城市经济增长的相关要素的集聚，进而通过要素投入的规模效益、集聚效益来促进我国城市经济的增长。 为此，本文第二章首先介绍了经济基础理论、投入产出模型、累积因果效应模型和凯恩斯乘数模型等城市经济增长理论模型，并...Great progress in urban economic growth had been achieved since the foundation of P.R. China, especially since the implementation of reform and open policy in 1978. But, as it still had not been known about the functional mechanism and contribution of factors to urban economic growth in China, effects of policy for enhancing urban economic growth are not so good as anticipated. In order to agglome...学位：经济学博士院系专业：经济学院经济研究所_产业经济学学号：B20041601

完善我国高校学生资助体系的研究

本文考察了我国高校学生资助体系的现状和国内学者在完善学生资助体系方面的探索 ,提出了一些高校学生资助体系中存在的问题 ,由此就进一步完善我国的高校学生资助体系进行了初步地探讨

总部经济:概念与现状

一、总部经济概念 近年来,我国的一些城市或地区(见案例研究)提出要发展“总部经济”(“Headquarters Economy”)。一些地方政府还组织了针对总部经济的调查研究(如厦门市政府2002年下半年的《厦门发展“总部经济”的扶持政策及措施研究》、北京市的《论北京发展“总部经济”》、广州市的《发展总部经济阔步走向国际》等)。本文是在笔者参与的厦门市政府2002年的调研课题《厦门发展“总部

Application of Ammonium Oxalate in the Syntheses of LaAlO 3 and CeAlO 3 Precursors

报道了合成乳酸酯的新方法，即以乳酸和醇为原料，在对甲苯磺酸催化下以氧化钙为脱水剂，采用索氏提取器进行回流脱水合成乳酸酯.应用该方法，酯化反应时间缩短到3H，收率高达81%~98%.同时对影响收率诸因素进行了考察，最佳反应条件为乳酸醇对甲苯磺酸的摩尔比为24201La(NO 3) 3 ·6H 2O (or (NH 4) 2Ce(NO 3) 6) and Al(NO 3) 3·9H 2O according to the stoichiometric amounts were dissolved respectively in ammonium oxalate solution,Followed by drying to obtain the solid products.The products were powdered and pressed into pellets and then calcined at 600 ℃ and 700 ℃, respectively, resulting in LaAlO 3 and CeAlO 3 compounds with the perovskite structure.X ray and DSC analysis of the La precursor showed that the process of From the drying and decomposing of the precursor, via the Formation of the intermediate phase, to the transFormation to LaAlO 3 phase was complex.The application of so called soft chemistry method markedly decreased temperatures For the solid state reaction of the perovskite type oxides

SYNTHEESIS of CHLOROACETIC ESTER BY THE METHOD of CALCIUM OXIDE DEHYDRATION

报道了一种以氯乙酸和脂肪醇为原料合成氯乙酸酯的新方法,即在催化剂作用下,用氧化钙作脱水剂,采用索氏提取器进行回流脱水直接酯化。应用该方法,酯化反应时间仅需2~3H,产率高达93%~98%,同时对影响产率诸因素进行考察,确定了最佳反应条件This paper describes a new method of synthesis of chloroacetic ester From chloroacetic acid and Fatty alcohol, and the experiment is carried out by the action of catalytic agent, the dehydration of calcium oxide and the direct esteriFication using Soxhelt extraction apparatus.In this method, only 2～3 h of the reaction time iF the esteriFication are needed, and the yield is up to 93%～98%.The eFFects of varrious Factors on the reaction yields are examined and the best reaction conditions are Found out

Determination of the number of ψ(3686) events taken at BESIII

The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
