基于协整方法和VAR模型的中国行政管理成本变动分析

一、文献回顾:行政管理成本变动的原因长期以来,国家的行政管理成本问题一直受到学术界的关注。单从现有的定量研究成果看,对于行政管理成本变动的原因,大多数研究者从经济增长角度进行研究,但对于它如何影响政府规模,有两种截然不同的观点:一种观点认为,随着经济的发展,保证行使国家职能的公共支出要不断增加,政府消费性支出占国民所得的比重也不断上升。这就是所谓的“公共支出不断增长法则”,或称“政府活动扩张法则”,又称“瓦格纳法则”。20世纪以来,一些经济学家利用现代计量经济方法进行的研究也证实了这一“法则”。例如,Rubbinson…     

呆坏账核算的修订及其对我国核算影响的研究——1993年SNA修订问题研究系列之七

一、问题的提出1997年亚洲金融危机后,许多国家的银行和政府出现了大量的呆坏账,因此,泰国当局向国际国民核算工作组(ISWGNA)提出如何处理呆坏账的问题,希望工作组就应付利息计算给予解释,并确定一个标准和方法来冲销呆坏账,此方法应与其他主要宏观经济统计体系(国际收支、政府财政、货币与银行统计)保持一致。从我国的实际情况看,我国商业银行特别是四大国有商业银行中也存在大量的呆坏账,2005年全部商业银行不良贷款余额为1·3万亿元,不良贷款率为8·6%,其中很多不良贷款变为呆坏账(见表1)。所以,我国也面临着同样的呆坏账核算问题,研…     

INNOVACQ: Serials control at Boalt Hall

Many changes in the Law School Library have occurred during this past year because of INNOVACQ. Within the Serials/Acquisitions Section, almost all the routines and procedures have been radically redefined to allow for the computerization of serials control. There have been some staff reassignments and shifts in responsibility, and in most instances, old tasks and manual file maintenance have been done away with completely and replaced by work at a VDT. Naturally, the impact of INNOVACQ has also been felt in the Cataloging Section, and the instant availability of serials check-in and routing information in public services has certainly added a level of service that was never possible before. In addition, the immediate and up-to-date fiscal information has been a boon for both the library's collection development officers and the Library administration.Various staff members throughout the year have been working to clean up and upgrade different parts of the serials files and to add or exchange better information in a number of fields in each record. Past payment history has been keyed into over 2/3 of the records in the file. The records for all the loose-leaf services contracted for by the Library are not fully online.All the records for our California documents have been edited and check-in cards have been created for this large and obviously important part of the file. Conversion of the U.S. documents which had been deferred at the very beginning of the fiscal year, has begun and most entries now can be checked-in and claimed online.All invoices (both serials and monographs) for this fiscal year have been processed on INNOVACQ, and while there are still some vendor and fund anomalies, Boalt has better, more comprehensive — and certainly more accurate — financial records than ever before.A massive editing and claiming project has recently gotten under way. All titles on INNOVACQ are being checked against the shelf list to make sure that all the bibliographic elements in each record are in sync and are presented in a standard, retrievable (punctuation and spacing count in INNOVACQ) format. Routine claiming (as part of serials check-in) has been in place for some time now, and that activity was begun when that feature was delivered. A second part of the editing project, is however, to get the thousands of blank boxes out of the check-in screens where they will remain as claimable items until some sort of purging action is taken. The files are now being gone through (a simple command in INNOVACQ can allow one to review every check-in record in the system), our holdings are being checked on the shelves, and decisions to claim or replace the missing pieces are being made. We anticipate that this editing/ claiming project will take approximately half a year.The INNOVACQ system was pretty exciting when we first saw it demonstrated, and we were eager then to incorporate it into our technical processing activities here at Boalt. If anything, our enthusiasm has grown as the capabilities of INNOVACQ have been realized. Enhancement and refinement — some at our prompting, others by the design staff at Innovative Interfaces — over the past year have resulted in what we believe to be the most comprehensive and easy-to-use serials control system available. Our confidence was manifested when we shifted all of our acquisitions activities from RLIN to INNOVAQ at the beginning of our fiscal year in mid-1984.Many tasks remain for the Law Library in making the best use of the INNOVACQ system. The rapid acceptance by the public service staff and users has been heartening, and the continuing work to clean up the Serials Records has proven fruitful. System performance and maintenance have been outstanding, and we are excited about various possibilities for future growth. It has not been a simple nor uncomplicated process, but the gains realized by the Law library have been substantial.     

知识经济与广州城市性质功能定位

本文认为,面对２１ 世纪和知识经济时代,广州城市性质与功能的定位必然产生变化。广州要发展,必须发展知识经济,确立由４ 个系统组成的广州知识经济创新体系,确立教育和科技产业成为知识经济产业的一个支柱部门,成为广州发展的主导因素之一。为此,广州城市性质与功能应该定位为华南地区、东南亚地区的教育科技城和以知识经济产业为主体的多功能的中心城市

球墨铸铁曲轴的气体软氮化

柴油机的珠墨铸铁曲轴系重要零件,气体软氮化应用到球墨铸铁领域还是一种新工艺,而且比中频淬火效果好,提高了曲轴的抗疲劳和抗磨损的能力。本文对气体软氮化的基本原理、设备、工艺参数的选择和催渗方法进行了探讨,对软氮化后曲轴的尺寸形状误差、光洁度和机械性能的提高等进行了较详细的试验、分析和比较,结果,经气体软氮化后的曲轴不但尺寸形站误差符合图纸要求外,而且抛去轻微氧化层后光洁度还略有提高,曲轴安全系数由1.3～1.6提高到1.70～1.77,并且一般不再发生疲劳断(?),使用寿命比原来寿命增加3.32倍以上。
