我国对外技术依存度的测算及浅析

建设创新型国家成为国家的战略目标,而对外技术依存度的高低成为衡量创新型国家的一个重要指标。针对当前对外技术依存度算法的不足,提出一种全新的测算方法,从技术依存度的内涵出发系统地构造衡量指标和计量模型,运用因子分析方法对我国对外技术依存度进行了测算,并简析其原因。结果显示,中国的对外技术依存度在快速提高,并处于很高的水平,表明我国的技术对外依赖程度非常高,经济技术发展受制于人,我国亟需加强自主创新。

Exploring the mediating role of utilitarian value and hedonic value in the formation of oppositional loyalty in online communities

Our research expands the scope of the research on oppositional loyalty from brands to online communities. Online communities allow members to freely express their opinions and promote the occurrence of oppositional loyalty behaviours towards the communities. Oppositional loyalty is defined in this article that, for the purpose of strengthening the market position of their preferred community, members of the online community may express negative views or even show oppositional behaviour towards adversarial communities. In view of social capital theory, the study examines the effect of hedonic value and utilitarian value on oppositional loyalty in online communities. The results show that only hedonic value significantly affects oppositional loyalty; hedonic value mediates the effect of the three dimensions of social capital (network ties, identification, and common language) on oppositional loyalty. The study identifies that community type moderates the impact of social capital (identification and common language) on hedonic value but does not moderate the effect of social capital on utilitarian value. Finally, we find that members' oppositional loyalty towards their community can promote their community participation. This research provides recommendations for online community managers to manage and benefit from members' oppositional loyalty.

Is the Income Elasticity of the Willingness to Pay for Pollution Control Constant?

How willingness to pay for environmental quality changes as incomes rise is a central question in several areas of environmental economics. This paper explores both theoretically and empirically whether or not the willingness to pay (WTP) for pollution control varies with income. Our model indicates that the income elasticity of the marginal WTP for pollution reduction is only constant under very restrictive conditions. Our empirical analysis tests the null hypothesis that the elasticity of the WTP for pollution control with respect to income is constant, employing a multi-country contingent valuation study of eutrophication reduction in the Baltic Sea. Our findings reject this hypothesis, and estimate an income elasticity of the WTP for eutrophication control of 0.1–0.2 for low-income respondents and 0.6–0.7 for high-income respondents. Thus, our empirical results suggest that the elasticity is not constant but is always less than one. This has implications for how benefits transfer exercises, and for theoretical explanations of the environmental Kuznets curve.
