网上采购：还要准备些什么？

随着电子商务的迅速发展，网络技术的日益成熟。在政府采购工作中，要求采用网上采购方式的呼声越来越高。实施网上采购，不仅方便、快捷，而且交易成本低、信息公开化程度高，的确是一种很有发展前途的采购方式。从国外的情况看，许多发达乃至发展中国家都建立了大规模的因特网采购体系，如巴西，1998年3月开始建立全国范围的网上采购体系，当年进行网上采购5，600余件，总支出即比上年减少11％，取得了良好效果。对于从1998年才开始全面推行的我国政府采购工作而言，要建立我国的因特网采购体系，我们还需做些什么呢？

我省医药电子商务亦喜亦忧

一医药电子商务的作用（一）网上采购有利于规范药品购销行为，净化医药市场。由于医疗单位对药品实行联合采购的方式，上网的药品由专家委员会把关，非法医药市场经销的药品因不能提供合法的销售代理文件，无法通过专家委员会的合法性审查，堵住了假冒伪劣药品流入医院的路子，较好地保证了药品质量和临床用药的安全。（二）网上采购能够有效地遏制药品采购中的不正之风。联合采购采用了新的分工机制，改变了以医院为单位的分散决策，代之为采购集团的集体决策，将过去那种长期沿用的“人对人”交易模式改变为“人机对话”的交易模式，使过…

网络团购和传统渠道的冲突与互补

网络团购这个渠道是否能为企业带来新的利益增长点,这个利益增长点起到的作用能否大于网络团购对传统渠道可能形成的冲击,是值得研究的问题。研究表明,网络团购的作用不仅仅是为了达成交易量,同时也具有推广和宣传的作用,带来更多的潜在消费群体在传统渠道上进行消费;而传统渠道能为企业带来稳定的收益,是企业开展网络团购活动的基础。网络团购与传统渠道的关系是像企业的两支手,它们面临着不同的消费群体,并存在各自的优势与劣势,避免冲突并形成合作互补才是最佳途径。     

Effects of the risk sources and user involvement on e-commerce adoption: application to tourist services

Past research has focused on the dimensions (consequences) of perceived risk and the effect of global risk on e-commerce adoption by consumers. This paper uses a new approach to examine the influence of perceived risk on e-commerce adoption and, on the basis of the Theory of Planned behaviour (TPB), develops an integrative model that includes the effect of three risk sources (i.e. technology, vendor and product) on the attitude towards the website use and online purchasing intention of users. In addition, this study examines how involvement, one of the main determinants of consumer behaviour, affects the role of these sources of perceived risk in e-commerce adoption. The results obtained in a sample of 1083 users of tourist services suggest that technology risk is the main determinant of online purchasing intention, which is also influenced by the variables from the TPB model. For its part, the technology risk and vendor risk have a negative influence on attitude towards the website use. In addition, both types of risk have a higher negative effect on attitude in the case of high-involvement users, supporting the moderating influence of involvement on e-commerce adoption. From a practical point of view, the findings of this research help managers to implement actions aimed at reinforcing the users’ trust in their websites and, consequently, at fostering the online purchase.     

Revisiting Border Effect: Evidence from Taobao.com in China

Inherent home bias and trade barriers (particularly local protectionism in China), which are difficult to separate, are two main explanations of border effect. We attempt to solve this problem by analyzing online trade. Different from offline trade, inherent home bias is the only cause of online border effect because local governments are usually unable to restrict online trade. Thus, the difference between the border effect in online and offline trade can be reasonably interpreted as the existence of government protectionism in the offline market. We find a statistically significant difference between online and offline border effects in China, which can be interpreted as strong evidence that policy barriers remain significant and hinder interregional trade.     

Can online annual general meetings increase shareholders’ participation in corporate governance?

We find that annual shareholder meetings conducted online can significantly increase the participation of shareholders, especially minority shareholders. This finding is more evident when the cost of physically attending the annual meeting is higher and when the firm's ownership is more dispersed. We further document significant positive stock returns when firms initiate annual online meetings. We also find that such online meetings help improve corporate governance. Overall, we provide evidence that online shareholder meetings provide shareholders a cost-effective way to participate in governance issues.

Harm-advocating online content and subjective well-being: a cross-national study of new risks faced by youth

Harm-advocating online content includes pro-eating disorder, pro-self-harm, pro-suicide, and the positive portrayal of the deaths of real people (snuff or death sites). This material is often user-generated and easily accessible for an average online user, therefore offering a potential source of risk for many Internet users. This cross-sectional study examined the association between exposure to harm-advocating online content and users’ subjective well-being (SWB) among American (n = 1032) and Finnish (n = 555) young people aged 15–30. Exposure to different types of online harm-advocating content was prevalent in both countries. Lower SWB was associated with exposure to this material even when controlling for social networking site (SNS) activity and online and offline victimization. In the US sample, seeing death sites was not associated with SWB, but seeing other harm-advocating sites was. In both countries, those with high SNS activity were more likely to be exposed to online harm-advocating material. These results from two advanced information societies underline the importance of recognizing the existence of harmful online communities. These communities are grounded on social interaction that might involve risks for the well-being of adolescents and young adults.     

Identifying risk and mitigating gambling-related harm in online poker

The present paper conducts a critical analysis of the potential for gambling-related harm in relation to online poker participation, and a theoretical evaluation of current responsible gambling strategies employed to mitigate harm in online gambling and applies the evaluation of these strategies specifically to online poker gambling. Theoretically, the primary risk for harm in online poker is the rapid and continuous nature of poker provisions online, and has been demonstrated to be associated with disordered gambling behaviour, including the chasing of monetary losses. The following responsible gambling features were deemed relevant for consideration: informed player choice, voluntary self-exclusion, employee intervention, pre-commitment, in-game feedback, behavioural tracking tools, and age restriction and verification. Although current responsible gambling features are evaluated as theoretically robust, there remains a fundamental need for experimental validation of their effectiveness. Furthermore, despite online poker gamblers perceiving the responsible gambling features as valuable tools, in reality very few players regularly use available responsible gambling features. Ultimately, for the online poker gambling industry to retain market credibility and avoid substantial top-down regulation, it is imperative to demonstrate effectiveness of responsible gambling approaches, and increase customer utilisation of available harm-mitigation features.
