While different conceptions of the digital economy exist, there is a common ground where discussion on digital economy can be fostered. Taking the notion that digital economy as a continuum from the existing old economy, this paper regards the manufacturing sector of the digital equipment as the digital infrastructure. Upon this, this research attempts to analyze the supply and demand side development patterns of the infrastructure of the digital economy in Korea between 1989 and 2000 with the Bank of Korea's data in order to present the dynamic that brought the growth of digital economy. Research findings show that there has been an unique mechanism in the development of IT sector in Korea, while policy measures have been broadly identical to the promotion of other sectors. 相似文献

健康是人们关心的热点问题,对老年人来说,不仅要长寿,而且要健康,要尽可能长久地保持生活自理能力,提高自身的生命质量。回答我国老年人的日常生活不能自理期是压缩还是扩展了,分析影响老年人日常生活自理能力的因素。采用1992年和2002年两次全国老年调查数据,做分城乡、分性别、分年龄的不同老年人生活自理健康预期寿命的差异性分析。在1992年和2002年期间,城镇老年人和农村老年人日常生活不能自理期均在“扩展”;2002年卧床不起的疾病对老年人日常活动影响更大,老年人2002年比1992年在生活自理方面需要更多的照料资源。 相似文献

Since the passage of the Science and Technology Basic Law in 1999, Taiwanese universities have taken a more “scientific-economic” approach to protect and commercialize their research. This research mainly examines innovation activities such as patenting, licensing, and incubated startups in the context of Taiwanese higher education institutions (HEIs). The “scientific-economic” framework used to analyze the strategic aspects influencing these academic innovations includes (1) intellectual property managerial capabilities, (2) the strength of external industrial partnerships, (3) the university entrepreneurial orientation, and (4) government research policy. Four hypotheses were developed. Data were collected via a questionnaire with all 122 HEIs in Taiwan surveyed.The research reveals that the aspects of intellectual property managerial capability, HEI-industry partnerships, and academic entrepreneurial orientation are useful to distinguish the university's innovation performance on patent grants, licensing incomes, and firm incubation. Also, government support on research plays a moderating role in academic innovation. Managerial and policy implications for managing innovation effectively in universities were drawn. 相似文献

创业板市场对主板市场的冲击效应研究——香港股市与深圳中小企业板的经验证据与启示 总被引:9,自引:0,他引:9
文章首先利用香港股市主板市场与创业板市场数据探讨两者之间的互动关系,研究发现两个市场在波动性与流动性方面存在单向溢出效应,即创业板市场的推出并未加剧主板市场的波动性,也未显著分流主板市场的资金;同时,还利用沪深主板市场与深圳中小企业板市场数据分析主板与中小企业板市场之同的联动性,结果表明,仅深圳主板市场波动性单向溢出到中小企业板,沪深主板与中小企业板市场在流动性方面存在双向溢出效应.对此,针对创业板的推出时机与风险防范提出相应的建议. 相似文献

Mongolian nomadic culture and ecological culture: On the ecological reconstruction in the agro-pastoral mosaic zone in Northern China 总被引:1,自引:0,他引:1
After analyzing the grassland environmental characteristics and nomads vs. agrarian land use styles and their ecological and environmental influences in the arid and semiarid agro-pastoral mosaic zone in northern China, it was concluded that Mongolian nomadic culture is more close to the basic principles of the ecological culture in the modern sense. Mongolian nomadic culture has advantages over agrarian culture in ecology and environmental care, sustainable utilization of grasslands, and in sustainable human social economic development in the region. Generally speaking nomadic culture prevents desertification; whereas, agrarian culture facilitates desertification. Confliction between nomadic protection and agrarian destruction of grassland ecosystem is essentially focused on the problem of regional and even global ecological safety. Obviously, protection of ecological safety should be given priority because human social and economic existence, as well as development depend on and are decided by the vulnerable ecological safety in the arid and semiarid areas. Therefore expansion of cropping into the fragile ecosystem of arid lands was unfortunate. The long term sustainable management of these grassland ecosystems could benefit from reversal of policies that are exacerbating the problems of land degradation, and from the adoption of land use practices that have been successfully applied for centuries by Mongolian herders. Protection of grasslands and nomadic culture is far more important or even vital to the subsistence and sustainability of human and all other beings, compared to the protection of agrarian lifestyle and land cultivation. Protection of ecologic safety is protecting the premise and fundamental bases of economic and social development in the area. It is important to derive the rational elements of nomadic culture in construction of ecological culture, and in the ecological reconstruction in northern China. Based on analyzing and reasoning in line with the quintessence of nomadic culture summarized, some proposals on ecological reconstruction in the area are presented. 相似文献
