国家信息政策体系研究——领域划分与结构分析

文章首先确定了国家信息政策80个主要关键词,在此基础上,运用共词分析,聚类出了信息政策5个子领域,并将其呈现在映射图中,以展现信息政策体系结构.进一步地,将其同Rowlands的结果对比分析,发现我国关于隐私保护方面存在政策缺失,以及在信息社会和基础设施方面更多地是使用了国家力量.     

Real time search on the web: Queries,topics, and economic value

Real time search is an increasingly important area of information seeking on the Web. In this research, we analyze 1,005,296 user interactions with a real time search engine over a 190 day period. Using query log analysis, we investigate searching behavior, categorize search topics, and measure the economic value of this real time search stream. We examine aggregate usage of the search engine, including number of users, queries, and terms. We then classify queries into subject categories using the Google Directory topical hierarchy. We next estimate the economic value of the real time search traffic using the Google AdWords keyword advertising platform. Results shows that 30% of the queries were unique (used only once in the entire dataset), which is low compared to traditional Web searching. Also, 60% of the search traffic comes from the search engine’s application program interface, indicating that real time search is heavily leveraged by other applications. There are many repeated queries over time via these application program interfaces, perhaps indicating both long term interest in a topic and the polling nature of real time queries. Concerning search topics, the most used terms dealt with technology, entertainment, and politics, reflecting both the temporal nature of the queries and, perhaps, an early adopter user-based. However, 36% of the queries indicate some geographical affinity, pointing to a location-based aspect to real time search. In terms of economic value, we calculate this real time search stream to be worth approximately US $33,000,000 (US $33 M) on the online advertising market at the time of the study. We discuss the implications for search engines and content providers as real time content increasingly enters the main stream as an information source.     

中国高新技术产业税收优惠政策文本量化研究

税收优惠政策在推动高新技术产业发展方面具有积极作用。从20世纪80年代中期以来,中国制定了一系列税收优惠政策以鼓励和促进中国相关产业的发展。本文对中国自1987-2008年间近百份高新技术产业税收优惠政策文本,以政策发布年度、政策优惠对象、政策优惠税种、政策优惠措施为分析维度进行频数统计和量化分析,在揭示中国高新技术产业税收优惠政策的总体状况和发展历程的同时,也指出中国高新技术产业税收优惠政策在提升中国自主创新能力中存在四方面问题--政策具有明显阶段性,年度频率、密度的不平衡,其连续性和稳定性亟待进一步提高;税收优惠对象以区域区分为主,忽视了产业性优惠导向;税收优惠税种主要涉及所得税和增值税,以支持企业创新的生产投入和成果转化为主,对企业研发过程则缺乏有力的税收优惠激励;税收优惠措施以直接优惠为主,对投资抵免、加速折旧、R&D费用加计扣除或税收抵免、科技开发准备金提取等间接性优惠措施的采用较少,并针对这些问题提出意见和建议。

Performance impact of research policy at the Chinese Academy of Sciences

We present evidence on productivity improvement experienced by the research institutes of the Chinese Academy of Sciences (CAS) after its implementation of the Knowledge Innovation Program (KIP). Using a balanced panel of data on R&D inputs and outputs of 59 research institutes in CAS, we analyze the productivity, technological and efficiency changes from 1997 to 2005. We document that the CAS research institutes have a productivity growth of 12.5% from 1998 to 2005, which can be further decomposed into 8.8% attributed to technological progress and 3.3% to efficiency improvement. Results of regional analysis show that institutes in Beijing and Shanghai, performed better than institutes in other regions during the same period.
