Review of Relationships Among Variables in TAM

The technology acceptance model （TAM） is an important tool in information technology research. Many scholars have applied the classical TAM to various research domains. However, the relationships between variables in these TAM models are not strongly desired. Thirty-four articles selected from international journals were analyzed to show that most of the relationships in the classical TAM are significant, but the stabilities of these relationships differ. The significant positive relationships between perceived ease of use and its independent variables are more stable than the others. Various factors can strengthen or weaken these relationships.     

Empirical Study of Consumers' Purchase Intentions in C2C Electronic Commerce

Electronic commerce is becoming increasingly important in business, but lack of intention to purchase has become a main barrier in the development of electronic commerce. Thus, effective measures are needed to promote consumers’ intentions to purchase in online consumer to consumer （C2C） stores. This paper postulates that five factors, the perceived ease of use of the website, perceived usefulness of the website, vendor competence, introduction and recommendations of third parties, and vendors’ attitude toward customers, influence consumers’ intentions to purchase in online C2C stores and this intention directly leads to their action to purchase from online C2C stores. The structural equation modeling （SEM） method was used to analyze empirical data, supporting these hypotheses except for the effect of vendor competence.     

Review of IT/IS Adoption and Decision-Making Behavior in Small Businesses

The increased use of information technologies has led to more research on information technology/information system (IT/IS) adoption and decision-making behavior in small businesses to improve information utilization. This paper presents an extensive review of the literature on IT/IS adoption to identify the key factors affecting small businesses based on comparison analysis. The review identifies the current interest in the adoption of Internet based IT and points out that the factors affecting different stages of the business lifecycle and research variables should be selected in terms of the different technology types. Especially, the review emphasizes the characteristics of external openings on the network in the research on e-commerce adoption. Future studies should focus on IT/IS adoption and implementation in small and medium-sized businesses during the development of small and medium-sized industrial clusters and specialty towns.     

社交网络交通信息出行者使用意向分析模型

为解决出行者对社交网络交通信息的使用意向缺少定量描述方法的问题,在技术接受模型的基础上,以感知有用性、感知易用性、感知风险性、使用意向等7个潜变量描述出行者的心理感受,构建社交网络交通信息使用意向分析模型,运用结构方程模型定量分析潜变量对使用意向的直接或间接影响效应。最后将模型应用于重庆市出行者实例分析中,结果表明：感知风险性(-0.41)对使用意向具有负向影响,其余变量对使用意向均为正向影响,其中感知易用性(0.48)、感知有用性(0.46)对使用意向的影响总效应最为显著。     

Extending TAM for Online Learning Systems: An Intrinsic Motivation Perspective

Impact of Internal Factors on Information Technology Adoption: An Empirical Investigation of Chinese Firms

Organizations differ significantly in their inclination to deploy information technology (IT). The factors that determine the organizational inclination to deploy IT need to be classified to help firms formulate an appropriate e-strategy. This paper discusses a framework that explains the influence of internal factors on IT adoption. The framework is based on quantitative data on IT adoption from 95 firms in China. The results highlight that the internal factors of leadership, organizational learning, and IT resources positively impact IT adoption. The study also shows that these factors are correlated.     

Inter-Organizational Coordination, IT Support, and Environment

Manufacturing organizations must know how to deal with uncertainty, manage environmental impact, effectively coordinate with suppliers, and use information technology （IT） to support coordination. Applying cybernetics and information processing theories, this study explores the relationship between organizational environment, inter-organizational coordination, IT support, and the effectiveness of interorganizational coordination. Using the case study method, data was collected from six manufacturing firms in China. The results show that inter-organizational system adoption is affected by organizational environment and is related to the management of inter-organizational coordination. Coordination and IT application affect the performance of inter-organizational coordination.     

Applying TAM in B2C E-Commerce Research: An Extended Model

As one of the most widely accepted adoption models in information systems research, the technology acceptance model （TAM） focuses exclusively on cognition-oriented constructs such as perceived usefulness and perceived ease of use. This perspective may have limited the explanatory power of TAM when it is utilized in studying consumers’ adoption intentions of online shopping. Based on the contrasts between e-commerce systems and traditional workplace information systems as well as empirical findings from a variety of recent e-commerce research works, this paper analyzes an extended model which integrates three additional constructs： trust, social presence, and perceived enjoyment. The interrelationship between these constructs is also explained. Empirical validations of this extended model are expected in future research.

基于结构方程模型的公司治理对企业技术创新影响分析

通过治理结构变革来推动技术创新,是增进企业活力、改善绩效的重要途径。以公司治理结构对企业技术创新的影响为研究主题,运用结构方程模型,通过从股权结构、董事会结构、管理层激励以及资本结构等方面进行实证研究,得出结论:国有持股比例越高越不利于企业技术创新活动的进行;独立董事以及董事会规模对企业技术创新投资的影响不显著;股权集中度越高,技术创新的投资越高;管理层激励与技术创新的投资有明显的正相关关系;企业负债率与技术创新则有明显的负相关关系。相比回归分析的统计方法,结构方程模型可以同时处理多个因变量,同时容许自变量和因变量含测量误差,还可以估计整个模型的拟合程度,因而对结构方程模型的运用增加了研究结果的精准性和说服力。
