通过问卷调查等方法,对广东省高校定向越野运动的开展现状与训练情况进行了调查。结果表明：广东省高校中本科层次高校的定向越野运动队开展相对较好,而专科层次开展相对较差。高校的定向越野课程的开设率或讲座的开设率都相对较低,高校定向运动队的训练方法主要是采取体技能结合的训练方法。建议：广东省高校（尤其是专科院校）应加强定向越野运动的宣传、普及;高校教练员应加强定向越野知识方面的培训等。 相似文献

目前,定向运动在我国有了一定的普及和发展,但依然存在一些问题,如:场地缺乏、器材不够完善、教材不统一、师资力量薄弱等诸多问题都有待进一步的解决。本文对福建水利电力职业技术学院学生的定向运动选修课现状进行调查与分析,提出了增加课时,提高对定向器材的使用以及田径普修课相结合并在高校中鼓励组织课外定向越野活动等建议,对今后高校定向越野运动开展与推广提供依据。 相似文献

有种乐观的观点认为,我国的环境质量已经出现拐点.我们利用跨国截面数据考察环境库兹涅茨曲线,结论显示,我国的人均国民收入与环境拐点还相距甚远,据此我们主张慎言环境拐点.基于跨国截面数据,我们还探讨了经济发展、技术进步、民主水平提高、产业结构升级、政府财政收入这些因素对环境质量的影响. 相似文献

Economic inequalities have increased in many countries since the 1980s, provoking calls for more income redistribution. One argument against increased redistribution is that it could hamper innovation and technological progress. To the best of our knowledge, this is the first paper that empirically investigates the relationship between government redistributive policies at the top of income distribution and innovative activity using new, high-quality, cross-country comparable panel data on income redistribution from the Distributional National Accounts. This study analyzes data from 34 advanced and emerging countries between 1980 and 2010. We find that redistribution has no negative impact on innovation in the cross-country setting. This result is robust to various measures of income redistribution and patent-based indicators of innovation, including patent counts, patent citations, and patent originality. 相似文献

A positive relationship exists between national technological size and technological diversification across fields of innovative activity. This paper shows how the nature of this relationship has changed historically. There has been a downward structural shift in the cross-country size-diversification frontier since 1965—for any given size countries have become less diversified or more narrowly concentrated in their technological specialisation. One explanation is that international technology sourcing by MNEs has led locations to focus on what they do best. A supporting factor may be a rise in technological interrelatedness, which encourages focus upon a specific selection of complementary combinations. 相似文献

Based on the critical case of ABB, this paper questions the relevance of using patents with multiple inventors from different countries (“cross-country patents”) as an indicator of international R&D collaboration. The study shows that less than half of ABB's cross-country patents are the result of international R&D collaboration as described by one of the more inclusive definitions found in previous literature. Only a third of the patents are the result of joint R&D activities between different MNC subsidiaries or firms. We also discuss the implications of our study for the assignment of patents to countries based on inventor addresses. 相似文献

This paper presents the results of an econometric approach to examine the determinants of scientific production at cross-country level. The paper aims not to provide accurate and robust estimates of investment elasticities (a doubtful task given the poor quality of the data sources and the modelling problems), but to develop and critically assess the validity of an empirical approach for characterising the production of science and its impact, from a comparative perspective. We employ and discuss the limitations of a production function approach to relate investment inputs to scientific outputs using a sample of 14 countries for which we have information on higher education research and development (HERD). The outputs are taken from the Thomson ISI® national science indicators (2002) database on published papers and citations. The inputs and outputs for this sample of countries have been recorded for a period of 21 years (1981-2002). A thorough discussion of the data shortcomings is provided. On the basis of this panel dataset we investigate the profile of the time lag between investment in HERD and research output and returns to national investment in science. We devote particular attention to analysing the presence of cross-country spillovers. We show their relevance and underline the international effect of the US system. 相似文献

This article develops and tests a model examining the relationship between firm globalization, scope of e-commerce use, and firm performance, using data from a large-scale cross-country survey of firms from three industries. We find that globalization leads to both greater scope of e-commerce use and improved performance, measured as efficiency, coordination, and market impacts. Scope of e-commerce use also leads to greater firm performance of all three types. Globalization has differential effects on B2B and B2C e-commerce, however, such that highly global firms are more likely to do B2B but less likely to do B2C. Our findings provide support for Porter's (1986) thesis that upstream business activities (namely, B2B) are more global while downstream business activities (B2C) are more local or multidomestic. 相似文献
