Development of low-CO2-emission vehicles and utilization of local renewable energy for the vitalization of rural areas in Japan

Most of Japan's energy supply depends on imports from foreign countries, making the independence ratio of energy in Japan very low. The Fukushima nuclear power plant accident triggered by the Great East Japan Earthquake and Tsunami led to a mass shutdown of all the nuclear plants in Japan, a stoppage that is still in effect. In this paper, we review the energy supply situation and some social problems faced by rural areas in Japan. Given that lifestyles in rural Japan are reliant on automobiles, there is significant demand for the establishment of a sustainable mobility society. Furthermore, Japan is now entering an aging society ahead of other countries. In order to enhance the vitalization of rural areas and accelerate the establishment of sustainable society, our project developed low-CO₂-emission vehicles (i.e., a single-driver EV [micro-EV] and a low-speed E-bus) for elderly people and tourists through the cooperation of regional industries, a local university, and a city office. This paper also reports some trial test results on renewable energy utilization as the driving energy supply for these low-emission vehicles.

农村公路道路条件对交通安全的影响分析及设计对策

针对当前农村交通安全存在的问题,分析了道路条件对交通安全的影响,并给出了各类道路条件的设计对策。基于农村公路线形不合理,路基、路面材质不合格、强度过低,边沟结构不规范,桥涵宽度不当和防护设施缺损,平面交叉口缺乏标线施划、信号控制及有效视距等道路条件,给出了影响交通安全的范围及程度。针对上述影响交通安全的道路条件,给出了相应的规范化设计对策,有助于改善农村公路在山区、桥涵以及平面交叉口的交通运行条件。

Investor herding behaviour in globally listed shipping stocks

ABSTRACT

This study undertakes one of the first empirical attempts to investigate and contribute a set of innovative findings to investor herding behavior and herding spillover effects in globally listed shipping company stock returns. Distinguishing between OECD and Non-OECD markets, herding behavior is tested on a diversified set of shipping companies traded in international equity markets, over different business cycle phases, financial crises, and external shocks. A set of dynamic models, well established in the relevant behavioral finance literature, is implemented. Empirical evidence indicates investor herding behavior in shipping stock returns and herding spillover effects between different shipping sectors, albeit not robust in all cases. These challenging findings can have a material impact on efficient investment and financing decisions of shipping market players.

基于层次聚类分析的城乡公交线路诊断倡——以安宁市为例

合理设置城乡公交为城乡居民出行提供优质的公交服务,是打破城乡二元分割的重要手段之一。分析城乡居民出行特征和城乡公交服务特性,从公交乘客及公交企业2个角度,构建表征城乡公交线路物理、运营和公交客流特性的诊断指标体系。以安宁市15条城乡公交线路为例,对选取样本的8类指标数据进行主成分分析,经定量分析各成分贡献率后,确定出3个主成分(贡献率累计为92%)。将主成分作为城乡公交线路层次聚类分析的变量,作出线路的聚类关系图,构建判别函数定量诊断四类线路。结合实际验证了指标体系的合理性及诊断方法的有效性。提供了1种较准确高效的城乡公交线路诊断方法,并为城乡公交线路的优化与运营调整提供决策依据。
