多元城镇化、门槛效应与房地产库存：理论解释与实证检验

基于我国房地产和城镇化省际面板数据,构建面板模型和门槛效应模型,考量多元城镇化、门槛效应对房地产库存的影响.结果表明:人口城镇化、空间城镇化和产业城镇化对房地产库存具有显著抑制作用,资本城镇化对房地产库存具有显著促进作用,技术城镇化对房地产库存的影响存在门槛效应.随着技术城镇化跨越人均可支配收入相应门槛值,其对房地产库存的影响由显著到不显著再到非常显著,由促进作用转变为抑制作用,影响系数的绝对值也转变为较大.

Turning to the dark side: Challenging the hegemonic positivity of the creativity discourse

Using a Laclauian discourse approach this paper challenges the hegemony of articulations framing creativity as good, necessary, and as a source of valuable outcomes for organizations and individuals. Instead, this paper argues that creativity has a ‘dark side’, referring to that which is harmful and may result in pain, loss or suffering. We analyze and expose the hegemonic positivity of the creativity discourse within organization studies and discuss the implications of this hegemony. We conclude that the dark side of creativity has been subverted in the discourse and requires further scholarly exploration. To promote a greyer research agenda of creativity in organizations, we offer three theorizations of the dark side of creativity as antagonisms to the hegemony – the individual, collective, and critical. By challenging the hegemonic positivity of creativity and by providing a number of research imaginaries, this paper invites scholars to broaden the discourse and to embrace a more greyer understanding of creativity in organization studies.

一种S型的超宽带左手结构设计

文章在对S型左手材料结构进行理论分析的基础上,提出一种S型超宽带左手结构。通过电磁仿真软件Ansoft HFSS对该结构的电磁波反射、透射特性进行模拟,并运用NRW方法从中提取出该结构的有效介电常数和有效磁导率。结果表明：在55．5～66．5GHz频带内,该结构具有稳定的双负特性,相对带宽为9％,这对当前超宽带左手材料...     

Platform market competition with endogenous side decisions

This paper develops a framework to analyze platform competition in two‐sided markets in which agents endogenously decide on which side of a platform to join. We characterize the equilibrium pricing structure and perform a comparative statics analysis on how the distribution of agents’ preferences affects the platforms’ profits. We also show that the market equilibrium under profit‐maximizing platforms leads to the first best social surplus, which illustrates the importance of the price mechanism to induce more balanced participation across the two sides. This framework can be applied to analyze market competition for “rental” or “sharing” platforms. In addition, we extend our analysis to consider an initial investment stage, which makes participants the owner of some durable goods to rent out.
