发达国家住房福利政策的演变及启示——我国公租房领域供给侧结构性改革探析

我国公租房领域存在投资主体单一、政府财政压力大、市场参与度不够、配置低效、供需失衡及错配、贫富分区程度加大等问题，需通过推进供给侧结构性改革来予以解决。发达国家住房福利政策的演变表明，住房政策应与住房市场供需状况相适应，政府所扮演的角色须从“公共住房的直接供给者”走向“市场化供给的环境营造者”，即从“补砖头”到“补人头”是住房福利政策演进的必然趋势。我国公租房领域供给侧结构性改革应与住房供求情况相匹配。一方面，要转变政府职能，从政府实物配给逐步过渡到市场化供给；另一方面，要积极打造健康的住宅租赁投资市场以促进公租房供给市场化，并通过开发配建和货币化补贴等措施促成公租房“隐形化”混合居住模式。     

Urban pollution and road infrastructure: A case study of China

Urban road infrastructure is crucial in affecting air pollution. Yet, little is known about the roles played by road width vs road length. This paper attempts to fill this gap by estimating the effects of road infrastructure on PM₁₀ using city-level data from China. Our robust modeling results show that the road density index, defined as the ratio of road surface area to city territory size, is negatively correlated with PM₁₀. More importantly, when the road width and length components of the road density variable are separately included in the regression models, the width is found to be significantly and negatively correlated with PM₁₀, whereas the correlation with the length variable is insignificant. This is expected as increases in road width can help mitigate congestion, improve fuel efficiency, and thus reduce emissions. On the contrary, extending roads to new or unconnected areas is likely to bring more vehicles onto the roads and extend average driving time. Our findings appeal for careful consideration of the trade-off between road width (lane numbers) and road length when planning and constructing urban road infrastructure.     

The behavior of money demand in the Chinese hyperinflation

In this paper I study the behavior of money demand during the episode of hyperinflation that occurred in China after World War II. I consider two popular and competing money demand specifications – the log–log and the semi-log – and show that the log–log performs better than the semi-log in its ability to track the behavior of the money demand. The choice between the two specifications is of great importance, as it implies that welfare cost estimates are very different for hyperinflation. The findings also contribute to the understanding of Cagan’s paradox and the failure of Cagan inflationary finance models. The paradox might be attributable to the popular semi-log schedule for money demand, and the log–log schedule might be an appropriate form for the analysis of hyperinflation.     

市外旅行商行为与重庆旅游地营销匹配度探讨——基于网络调查视角

旅行商是连接旅游者和旅游地的桥梁。虽然旅行商与旅游地之间形成密不可分的利益关系,但在现实的旅行商和旅游地关系中,却存在较多的问题:个别大型旅行商"绑架"要挟旅游地,旅游地营销战略与旅行商推荐线路性质不匹配等。以压力-状态-响应理论和刺激-反映理论为指导,选取2010年和2011年国家旅游局发布的100强上榜旅行商中的重庆旅游地以外的60家旅行商为样本,通过网络调查方法,获取其推介的重庆旅游线路的相关情况,并加以分析整理,再结合重庆市旅游营销的具体实践,探求二者之间的匹配响应关系,得出市外旅行商和重庆旅游地营销之间存在匹配响应较低的结论,其结果是大大降低重庆旅游营销效果。最后,文章给出旅游地和旅行商之间匹配关系调整的一些对策,以期对重庆旅游营销有所裨益。     

Financial sector in resource-dependent economies

This paper examines financial sector characteristics in resource-dependent economies. Using an extensive data set covering 128 countries for the period 1995 to 2009, we present empirical evidence that the banking sector tends to be smaller in resource-dependent economies. Moreover, we locate a low threshold level at which the higher resource-dependence begins to be harmful for domestic banking sector. We also find evidence that the use of market-based financing is more common in resource-dependent economies. Further, our results suggest that a financial sector formed according to the needs of the resource sector might be unfavorable for emerging businesses, thereby hampering economic diversification and reinforcing the resource curse.     

The effect of financial transaction tax on market liquidity and volatility: An Italian perspective

This paper investigates the effect of the Financial Transaction Tax announcement, 29 December 2012, and the tax introduction, 1 March 2013, on the liquidity and volatility of the affected Italian stocks. The paper examines two-month windows of daily observations before and after each event. To assess the change in liquidity in pre- and post-event samples, the Mann–Whitney U-test for the equality of medians is employed, while for the assessment of volatility change, we apply the Levene test and its modifications for homogeneity of variances. The paper documents that the announcement of the tax positively affects market liquidity, whereas there is a dramatic decrease in liquidity as a result of tax introduction. It implies that the trading costs of the affected equities decrease after the tax announcement and significantly increase after the tax introduction events. As for volatility, the results mainly indicate no statistically significant changes between the pre- and post-tax announcement and introduction events.

The impact of farmland property rights security on the farmland investment in rural China

This paper aims to estimate the effect of the security of farmland property rights on land-attached and long-term investment. Based on the data from a nationally representative sample with 5887 plots of 1175 households among 5 provinces in rural China, we adopt Probit, Ordinary Least Squares / Tobit, and the household fixed effect methods to yield the consistent results. The results show that the security of farmland property rights have significant and positive effects on the possibility and amount of the overall farmland investment. However, it has different effects on the different types of investments. The share of farmland retained significantly affects the investments in soil quality improvement and changing use of the plots but does not affect the investment in water conservancy facilities. The types of farmland property rights affect investments in water conservancy facilities and changing use of plots, but do not affect investment in soil quality improvement. The findings imply that the Chinese government should be the principal investor in water conservancy facilities and enlarge the operational scale of farmland by facilitating farmland transfer to increase private investment.     

The micro-foundations of strategic ambidexterity: Chinese cross-border M&As,Mid-View thinking and integration management

Chinese cross-border mergers and acquisitions (M&As) display several unique properties in relation to the ways in which their international business operations are organised and managed. Their seemingly puzzling ‘light-touch’ integration approach can be significantly understood from a strategic ambidexterity perspective: on the one hand, the ‘light-touch’ enables the exploitation of the targets’ existing knowledge bases; on the other hand, elements of the ‘light-touch’ facilitate the exploration of the new knowledge arising from the collaboration between targets and acquirers. However, an important theoretical gap remains: why do Chinese companies deploy such a strategic ambidexterity approach in their post-acquisition integrations? This paper aims to fill this gap by proposing Mid-View thinking as a micro-foundation of strategic ambidexterity in integration management from a cultural and philosophical perspective. To illuminate our conceptualization and argument, we conducted qualitative in-depth interviews with CEOs/high-level managers of acquired German companies. Communication approach and organizational control—as two critical aspects in integration management—reveal how Mid-View thinking can serve as a micro-foundation of strategic ambidexterity. We conclude this paper by presenting its theoretical contributions, managerial implications, and future research directions.
