A tale of two literatures: Transaction costs and property rights in innovation outsourcing

This paper investigates the relative importance of property rights and transactions cost factors in driving the decision of firms to outsource innovation. Using data for over 8000 firms from the UK Community Innovation Survey, we find that property right factors dominate over transaction cost factors. Transaction cost variables are more important for process innovation, while property rights variables are more significant for firms involved in product innovation. In addition, we find that firms involved in process innovation have a higher probability of outsourcing innovation than firms involved in product innovation.     

Openness and innovation—Home and export demand effects on manufacturing innovation: Panel data evidence for Ireland and Switzerland

Recent studies in the tradition of Schmookler have re-emphasised the potential role of demand in stimulating innovation. Here, we reconsider the role of ‘home’ and ‘export’ market demand in stimulating manufacturing innovation using comparable panel data for two small open economies - Ireland and Switzerland. Our analysis is based on the estimation of reduced form innovation production functions using panel data estimators over the sample period 1994-2005. For a range of innovation indicators, however, we find little evidence of any significant market demand effects, with innovation performance instead determined largely by firm-level capability effects and characteristics. In policy and strategy terms this suggests the continued value of measures to improve innovation capability regardless of market demand conditions. In more methodological terms our results suggest the validity of the usual assumption implicit in modelling innovation outputs that supply-side factors predominate.     

The role of ICT knowledge flows for international market share dynamics

This paper investigates the role of Information and Communication Technologies (ICTs) related knowledge flows for international market shares. Using bibliometric data on scientific publications, we analyse the relationship between the strength of 14 OECD countries in four ICT-related scientific fields and the ability of those countries to maintain and acquire export market shares in the OECD market, across 16 manufacturing industries over the period 1981-2003. We find that domestic and foreign ICT-related scientific knowledge flows have a positive and significant impact on export market shares in ICT industries, while only domestic flows positively affect export shares in non-ICT industries. We also find that small open economies benefit more than other countries from foreign knowledge flows both in ICT and in non-ICT industries.     

奥康纳分析教育哲学思想研究

丹尼尔·约翰·奥康纳批判了传统哲学,认为传统哲学存在四点不足,这为其分析教育哲学思想奠定了理论基础;他用分析哲学的方法论述了语言分析的重要性,并对诸如教育、教育理论等重要概念作了深入的语言分析.奥康纳的理论在教育哲学界引起了不小的反响,同时也引起不少争议,其对传统哲学的批判有其一定的道理,对教育哲学的研究具有启发性.     

大气污染对云冈石窟的风化侵蚀及防护对策

云冈石窟地区大气污染较为严重.大气中的污染物主要是SO2、工业粉尘及粉尘中的金属元素,其含量皆严重超标.在有水份的环境中,通过金属离子的催化作用,SO2容易生成H2SO4或酸性物质,再与石质文物表层中CaCO3作用,生成CaSO4*2H2O, 导致风化侵蚀.     

我国高校学科馆员制度实施十年回顾

十年前,清华大学图书馆在我国率先实行学科馆员制度,正式把国外的先进管理制度引入国内。近年来,我国多数高校图书馆纷纷设置了学科馆员制度,但在实行中发展不尽如人意。文章分析目前开展学科馆员制度实践中所存在的问题与不足,并就如何完善该制度应采取的措施和对策进行探讨。     

某城区挥发性有机物的臭氧生成潜势及源解析

基于福建省某市大气挥发性有机物的观测数据,分析其挥发性有机物的污染特征,研究臭氧(O3)生成潜势,采用正矩阵因子分解法(PMF)模型开展源解析。本次研究共检测出化合物115种,定量分析51种挥发性有机物,包括烷烃、烯烃以及芳香烃,其中烷烃和芳香烃含量最高,烯烃的O3生成潜势贡献最大(45%)。PMF模型源解析结果表明,挥发性有机物主要排放源包括机动车尾气排放、溶剂使用、植物源、生物质燃烧和工业过程,分别占比55.07%、9.37%、8.09%、12.01%和15.47%。
