高新技术企业发展一般规律研究 总被引：4，自引：0，他引：4
纵观各国高新技术企业发展历程可知 ,高新技术企业成长一般都要经历种子、创业、发展和成熟四个阶段。影响高新技术企业发展的诸因素在不同的成长阶段表现出各自的特征 ,又因国家、产业、企业的不同存在众多差异 ,但国内外学者的研究表明 ,它们在不同成长阶段的特征仍存在着一定的规律性。本文正是在国内外现有研究的基础上 ,从影响高新技术企业成长的三个主要因素———企业主体、融资战略、政府行为———着手 ,试图归纳出高新技术企业发展的一般规律。下图是笔者对三因素在各阶段的特征作一简单的归纳 : 一、不同阶段的企业主体企业主… 相似文献

信息系统的成功使用已成为提高企业绩效的关键要素,如何提升跨组织信息系统(IOS)在企业内外使用程度为企业带来价值已成为亟需解决的重要问题。文章基于IT管理气候的构念、企业知识理论和信息技术吸收理论,对IOS在成员企业内采纳后吸收阶段的影响因素进行了研究,构建了组织IT管理气候和组织知识应用过程对IOS吸收的理论模型。运用偏最小二乘（PLS）结构方程模型方法检验了模型的路径和假设。结果表明IT管理气候和知识应用过程对IOS吸收具有显著的正向影响,并且知识应用过程在组织IT管理气候对IOS吸收影响中起完全中介的作用。研究结论将丰富信息系统采纳吸收理论,对实施企业有效地吸收IOS具有指导作用。 相似文献

创业拼凑动态作用研究对于突破新企业创建和成长中的资源约束具有重要意义,但目前关于拼凑过程与新企业发展阶段的动态匹配性问题研究,尤其是针对转型经济情境的实证研究还不多见。因此,基于创业拼凑理论和新企业成长理论,构建了创业拼凑对新企业绩效影响的动态模型,并结合我国创业实际,提出了在新企业初创阶段和早期成长阶段创业拼凑对财务绩效与成长绩效影响的理论假设。利用212家新企业的调研数据进行实证研究,结果表明:创业拼凑对初创阶段和早期成长阶段的新企业财务绩效均具有显著直接功效;创业拼凑对初创阶段的新企业成长绩效具有正向影响,但创业拼凑与早期成长阶段的新企业成长绩效关系并不显著。 相似文献

The main objectives of this research were to compare and contrast the findings of the relationships among different stages of information systems (IS) strategic planning, system planning, plan implementation, and IS effectiveness across various organizations in Taiwan. The intent was to take a broad look at the key concerns of IS planning across cultures. The relationships among three phases of planning (strategic planning, systems planning, and plan implementation), and their relationships with user satisfaction were examined. Five hypotheses are used to examine the relationships. The correlation analysis results support the following hypotheses: (1) the extent of IS systems planning is positively associated with the extent of IS strategic planning; (2) the extent of plan implementation is positively associated with the extent of IS systems planning; and (3) the extent of IS strategic planning is positively associated with the extent of user satisfaction. IS systems planning has no effect on user satisfaction. IS plan implementation has no relationship with user satisfaction. 相似文献

根据甘肃省河东地区15个气象站点50年的气象资料,利用FAOPenman-Monteith模型和所提供的作物系数计算出各站点春玉米不同生育阶段的作物需水量,在此基础上计算出作物水分亏缺指数(CWDI),并划分河东地区的干旱等级,分析春玉米干旱发生的时空特征。结果表明:在春玉米生长季内,CWDI呈现先增大后减小的趋势,其中最大值出现在6月中下旬,且每旬的CWDI值均大于10%,即在作物整个生长季,降水都无法满足春玉米需水的要求。不同等级干旱发生的频率:轻旱8%～20%;中旱7%～23%;重旱0～17%;特旱0～47%。生长季内,河东地区春玉米干旱发生程度基本由南向北递增,不同生育阶段干旱的严重程度:抽雄-开花期>拔节期>乳熟前期>出苗-七叶期>乳熟后期-成熟期。近50年来,出苗-七叶期和拔节期的干旱有逐渐缓解的趋势;抽雄-开花期和乳熟前期干旱变化的趋势大致相同:20世纪60年代中后期及70年代初为干旱的严重时期,70年代中后期有所缓解,至今又有加重的趋势;乳熟后期-成熟期,近50年来干旱有加重的趋势。 相似文献

中国水资源可持续利用评价指标体系研究进展 总被引：20，自引：4，他引：20
本文在归纳水资源评价分类基础上，论述了水资源可持续利用评价指标体系（Indicators system for sustainability assessment of water resources use，ISSAWRU）的研究基础，即可持续发展评价指标体系与水资源评价指标体系的研究现状，指出SAWRU需要ISSAWRU。水资源评价方法按指标数量可分为单项指标法、多项指标法和指标体系法。水资源评价所需指标数量因评价内容而异。综合评价常需要用指标体系法。SAWRU是水资源常规评价结合可持续发展思想发展形成的一种多属性综合评价。由于水资源系统在人口增长、经济发展压力下日趋复杂化，其可持续性影响因素也复杂多变，其可持续性度量具有不确定性。指标体系是衡量具有不确定性的复杂系统可持续状态的良好工具。我国水资源综合评价指标体系研究的指标筛选原则和方法、指标体系构建方法及指标体系应用方法日趋多样化，但仍存在不少问题，特别是如何构建和应用科学的指标体系SAWRU充分表征水资源可持续利用内涵。建议今后多关注主要用水部门指标体系构建、构建过程整体性、新理论新技术成果吸收等研究，加强SAWRU内涵对ISSAWRU构建的指导作用，从而提高指标体系的通用性和科学性。 相似文献

This study theorizes two information systems (IS) use behaviors associated with individuals’ behavioral intention of mobile health (mHealth) services. Emergency use refers to individuals’ use of IS in emergency situations. Routine use refers to individuals’ use of IS on a basis. We adopt motivation theory as our overarching theoretical lens through which we investigate the influence of individuals’ different motivation incentives on their emergency and routine use intentions of mHealth services. We also investigate the influences of technological and psychological antecedents on extrinsic and intrinsic motivations. Based on data collected from 241 participants, we find that perceived usefulness enhances people’s emergency and routine use intentions of mHealth services and that perceived enjoyment positively influences routine use intention. In addition, we find that perceived source credibility, perceived service availability, and perceived diagnosticity influence perceived usefulness (extrinsic motivation), whereas perceived autonomy, perceived competence, perceived relatedness, and curiosity affect perceived enjoyment (intrinsic motivation). This research offers insights for IS literature regarding mHealth emergency and routine use behaviors. 相似文献

家庭生命周期是影响农户行为和决策的重要因素,从家庭生命周期视角研究农户宅基地退出意愿的影响因素,有助于识别农户的不同政策需求和阶段演变规律。本文阐释了家庭生命周期对农户宅基地退出意愿的综合影响和具体影响机理,并运用四川省典型地区的农户调研数据进行实证分析。结果表明：①家庭生命周期对宅基地退出意愿的具体影响主要体现在住宅需求、劳动分工和供养负担3个方面;②家庭生命周期的复合影响在于,处于家庭生命周期不同阶段的农户宅基地退出意愿存在显著差异,随家庭生命周期演变呈“N型”（即低—高—低—高）变化趋势;③不同家庭生命周期类型农户宅基地退出意愿的关键影响因素存在差异,其中成长核心家庭更关注子女教育和家庭资本积累,成熟核心家庭更倾向于城镇迁移,扩大家庭Ⅰ更在意供养能力提升。因此,政府应当在普适性政策下采取差异化措施以回应农户不同家庭特征和不同家庭生命周期阶段的政策需求。 相似文献

IS research predominantly presumes that the success factors of IT service have one-dimensional influences: the higher (or lower), the better. Sporadic arguments, however, have been made that, depending on the antecedent, such a monolithic premise may not sustainable. Despite the rich evidence of the dichotomous role of success factors on measured consequences in non-IS fields, especially in the marketing discipline, theoretical and empirical efforts to examine this duality have received limited attention in IS research. Especially, no previous IS study took the extended duality position in which the role of success conditions can be any of pure enabler, pure inhibitor, asymmetric bi-directional influencer or symmetric bi-directional influencer . The extended duality becomes the theoretical thesis of this research, setting it apart from the scant IS research that viewed duality through the rather simplified lens of statistical significance in each direction. To test the validity of the extended duality theory in the IT service context, cross-sectional survey data were gathered on post-adoption usage of mobile data services (or MDS), the most prevalent form of IT service. Frequently used success conditions of IT service – system quality, information quality, economic value and self-efficacy – are chosen as the explanatory variables. The analysis suggests that success conditions of IT service can have a highly divergent and diversified form of duality effects on measured outcomes. The findings have important practical and theoretical implications to practitioners and researchers. 相似文献

The utilization of contract research results in a developing country was analyzed according to the stages of technological innovation and transfer. Three innovation stages such as project contract (proposal success), project solution (technical success), and project implementation (commercial success) are employed in this study, focusing on the identification of significant factors affecting the success in each stage. The factors influencing the successes in the project contract and implementation stages are mostly similar while the factors important in the technical success are somewhat different. The data analyses indicate that only a few factors seemed to significantly affect the successful project contract while more than a score of variables were considered to be important for the successful implementation of the contract research results. This implies that even though the success of the early stage of innovation can be relatively easily accomplished, the success of the final stage cannot be so easily accomplished. According to the findings of the study, there are at least two unique environmental factors for the successful innovation and transfer of indigenous technology in a developing country, Korea: (1) the vulnerability of domestic technology to the foreign technology from advanced countries, and (2) the strong influences of government intervention, whether they are advantageous to the success of innovation. Some methodological as well as theoretical issues for the improved understanding of innovation and technology transfer are discussed. 相似文献

旅游干扰对草原旅游点植被的影响——以内蒙古希拉穆仁草原金马鞍旅游点为例 总被引：1，自引：0，他引：1
近年来,随着内蒙古希拉穆仁草原旅游区旅游设施的不断建设和旅游活动的增加,其草原环境岛屿化现象严重。为保护草原景观和当地生态环境,探索草原旅游干扰的基本特点和规律具有十分重要的意义,也可为调控旅游干扰和实施规划与管理提供重要依据和理论支撑。在诸多的旅游干扰影响因素中,游客的活动和践踏以及车辆的碾压是草原旅游点及周边旅游环境产生变化的直接影响因素,而其影响又直接反映在该立地上的植被生长、发育和演替变化上。本文采用植物样方调查法对草原旅游点周围、不同活动区周边、不同等级道路上的植物种类构成与各种植物的相对密度、植被的总盖度、草群高度、植被地上生物量以及丰富度指数等进行了调查分析,以其相关指标变化来探究旅游干扰对草原旅游点植被的影响。 相似文献
