包西高速铁路引入鄂尔多斯地区方案研究

包西高速铁路作为我国"八纵八横"高速铁路通道中重要的纵向通道之一,建成后呼包鄂城市群和关中平原城市群将实现有效连接。鄂尔多斯市为典型的"一城双核"城市,包西高速铁路的引入将对地区客运布局产生较大影响,根据鄂尔多斯地区城市及铁路现状、城市总体规划及交通规划,结合地区客运量及特点,提出地区内包西高速铁路引入方案及车站设置方案,确定合理的引入及客站布点,研究地区内高速铁路客站布局,结合地区客流特点,确定高速铁路车站分工;合理确定引入地区线、站位方案将有助于完善鄂尔多斯铁路枢纽的客运铁路布局,有助于完善鄂尔多斯地区高速铁路网络,提升呼包鄂城市群的辐射效应,促进城市建设和经济发展。     

Official rotation and corporate innovation: Evidence from the governor rotation

Rotation is a practice whereby officials are regularly moved between equally ranked positions. Focusing on governor rotation, this paper examines the effect of official rotation on corporate innovation in China. First, we find that official rotation significantly promotes corporate innovation, including enterprises’ innovation investment, quantity, and quality. Second, we find that the effect of official rotation on corporate innovation varies because of official and regional heterogeneity. Officials rotating from other provinces significantly stimulate corporate innovation, but officials rotating from the central government have an insignificant influence on corporate innovation. In addition, officials rotating to non-eastern regions significantly enhance corporate innovation, while officials rotating to eastern regions have a negligible impact on corporate innovation. We further examine the driving mechanism behind the effect of official rotation on corporate innovation and find that officials rotating from eastern regions to non-eastern regions can significantly promote corporate innovation, but officials rotating from non-eastern regions to eastern regions do not boost corporate innovation. These findings imply that the different effects of official rotation on corporate innovation are due to the official experience effect. We also find that official rotation can promote corporate innovation through reducing corporate charitable donations and increasing corporate innovation subsidies. In a supplementary analysis, we find that GDP-oriented performance appraisal pressure weakens the effect of official rotation on corporate innovation. The lower the pressure on officials regarding their performance, the more significant the effect of official rotation on corporate innovation. In addition, official rotation can significantly promote the development of the regional economy and improve the GDP growth rate via corporate innovation, which is a micro-level economic growth effect of official rotation. Overall, our findings further verify the economic effect of official rotation and extend our understanding of the influencing factors of corporate innovation from the perspective of the official governance system. Our findings also have clear policy implications for how the government can improve the official governance model to promote corporate innovation during the transition period of the national innovation system.     

东北地区产业升级的困境与出路

产业结构的优化升级对于推动区域经济协调发展具有重要意义。目前，东北地区的产业发展仍未摆脱结构不合理、布局趋同、国有资产负债重、企业竞争力不强的困境。制约产业结构优化升级的因素在于思想观念保守、产业融合度低和制度环境不佳。需要突破某些认识误区、优化政策环境、发展替代和后续产业。     

基于卷积神经网络的列车检测算法研究

列车检测作为列车自动驾驶的核心技术,可以有效地降低列车追尾等事故造成的人身危险和财产损失。为实现精准的列车检测,选用改进的卷积神经网络(PVANET)对输入图像进行特征提取,在此基础上,采用候选区域网络,从生成的特征图里滑动搜索,判断出图像中可能为列车的区域位置,并进一步采用快速区域卷积神经网络对每个候选区域进行分类,计算出其所属类别的置信度,同时精确定位列车。经验证,该方法适应范围广、鲁棒性高,可以有效地检测不同环境光强及不同朝向的列车,保障列车安全,为列车自动驾驶及辅助驾驶提供安全保障。     

Implementing efficient conservation portfolio design

Modern tools for cost-effective conservation reserve site planning require the planner to have information about spatial distributions of conservation costs and benefits. Climate change creates unprecedented uncertainty about future land values and species habitat ranges, such that conservation scientists cannot map costs and benefits with certainty anymore. This paper contributes to the literature on the economics of conservation in the face of climate change uncertainty. It advances a new method for using modern portfolio theory to choose lands to protect that yield total conservation returns with less uncertainty. It explores the implications for portfolio recommendations of variation in the correlations between ecological and land-value responses to climate change. It also tests the robustness of the method to shortcuts that might be taken to simplify analysis, identifying problems that arise if conservation costs are ignored in portfolio analysis and demonstrating when portfolio recommendations are sensitive to how ecological benefits are quantified.

Measuring transit oriented development: a spatial multi criteria assessment approach for the City Region Arnhem and Nijmegen

Transit Oriented Development (TOD) is a planning approach that can stimulate sustainable development by encouraging better land use and transport integration. Arnhem Nijmegen City Region, a regional planning body, in the Netherlands, aims to promote sustainable development in their region and control the current pattern of increased use of cars vis-à-vis transit for longer commutes. Planning for TOD can help achieve this aim. It is believed that measuring the existing levels of TOD is a prerequisite for TOD planning and that it can be done using a TOD Index proposed in this research. A TOD Index measures multiple spatial indicators and aggregates them under the SMCA framework to arrive at a comprehensive value depicting the existing levels of TOD at a location or an area. Using this TOD Index, TOD levels were measured over the entire City Region covering approx. 1000 km². High levels of TOD imply that the urban development’s characteristics, at that location, are ripe for use of transit and these high levels, as expected, were found in the urban areas of Arnhem and Nijmegen. From the results of TOD Index measurement, using hot-spot analysis, those locations were identified that have high TOD levels but poor transit connectivity. These locations are accordingly recommended for better transit connectivity. As a part of our future work, it is intended to use the TOD Index to elevate TOD levels around existing transit nodes.
