Technology evaluation in Taiwan's technology industries: Strategies, trajectories, and innovations

Technology evaluation, as an organizational process, is the essential ability to comprehend the values of technologies very soon after they emerge. Meanwhile, the technology evaluation process is inevitably influenced by the firm's industrial context, such as its technological trajectory. This study defines technology evaluation strategy in terms of the processes, methods, and participants involved, and uses this definition as a taxonomy to explore different types of technology evaluation strategies. A survey on the technological industries is conducted to explore types of technology evaluation strategies and their relationships with the advantages of different types of innovation under the effects of different technological trajectories. The survey identifies four types of technology evaluation strategies, namely, those of the flexible executive strategist, the emergent executive intuitionist, the deliberate quantitative strategist, and the deliberate consensual strategist, are identified. This study has found that certain types of technology evaluation strategies have better innovation performances than the others. The patterns of technological trajectories are also found to influence a firm's technology evaluation strategy and the advantages of certain types of innovations. The established explanations of the relationships among the technological trajectory, innovation type, and technology evaluation strategies may guide technology businesses to develop a better technology evaluation capability. The theoretical framework developed in this research enriches the strategic management literature with a new taxonomy for technology evaluation strategies.     

新型信贷模式下完善农村担保贷款机制的思考

农村经济发展的不平衡制约了现行传统农村信贷投放的规模和效益,而新的联保贷款和担保贷款模式既不需农户的实物抵押,也部分规避了信贷双方信息不对称的风险。要完善农村担保贷款制度,应采取措施积极扩大贷款担保主体;发挥政府对贷款的引导和保障功能;拓展涉农企业对农村信贷的担保职能;完善农村信贷激励机制;大力拓展对"三农"的金融保险业务;建立农村基层干部对农贷的奖励和责任机制。     

Exploring the use of travel information – identifying contextual market segmentation in Seoul, Korea

As the amount of information is rapidly growing, and ubiquitous urban environments are emerging, the question which kind of information to provide is a major challenge for commercial and public travel-information service providers alike. This paper reports the analyses of recent data, collected in Metropolitan Seoul, about the acquisition of travel information. The study applies CHAID analysis to find homogeneous segments in travel information acquisition. Findings indicate that contextual variables are crucial to explain information acquisition behaviour, depending on decision context. The implication is that both socioeconomic and contextual variables are important to better understand the acquisition (and provision) of travel information. The results have important implications for managers and policy-makers, in particular in the way they respond to dynamic, contextual market segmentation.     

中国情境下口碑传播对农村居民购买决策影响的实证分析

口碑传播作为我国农村居民在生活中传播信息内容最丰富、最受信任的沟通方式,极大地影响着农村消费者的购买选择。本文从口碑传受双方特征、口碑信息类型与农村居民购买决策之间的关系入手,得出传播者专业能力对口碑在农村消费群体中传播效果的影响最大,意见领袖居其次,感知风险、关系强度和口碑信息类型也发挥着不同程度的影响,且产品类别的调节作用显著。这说明企业要想提高自身在农村市场的竞争力,积极开展口碑营销是行之有效的途径,应不遗余力地从各方面着手与农村居民建立联系,针对不同产品类别加强口碑管理。     

新型农村社会养老保险制度探析

新型农村社会养老保险制度的试点推行,标志着中国农村养老保障制度体系建设向前迈出了一大步。然而,新型农村社会养老保险制度还存在着制度运行的任意性和不稳定性、基金运行渠道和统筹层次限制了基金的保值增值能力、基金管理模式效率不高,补贴机制存在不稳定性等诸多问题。因此,建议:加快新型农村社会养老保险制度的立法保障;对个人账户养老金部分实行市场化管理;提高基金运营层次,拓宽投资渠道,合理划分中央和地方财政的责任,加大对中西部地区的财政支持等,以构建新型农村社会养老保险制度的长效运行机制。

富锦市不稳定耕地调查与处理对策

划分不稳定耕地类型,并调查其分布及规模,可以为耕地管理及区域农业发展提供依据.该文根据黑龙江省第二次土地调查的实际情况,将不稳定耕地划分为滩地、速生丰产林熟化地、林区多种经营地、开垦草原地、开垦荒地、开垦沼泽地、盐碱化地、高寒低温地、超坡地、其他耕地等10种类型.经调查,富锦市包含6类不稳定耕地,总面积1.979 1万hm2,全部分布于市属集体土地内,国有农场内没有不稳定耕地.根据富锦市不稳地耕地现状及利用中存在的问题,提出了处理对策.
