新型工业化思想的历史探析

我国探索社会主义工业化的道路 ,没有什么固定模式可以借鉴。党的十六大提出 :我国要走一条以信息化为基础的高效益的新型工业化道路。新型工业化道路的“新” ,体现了中国不同于西方发达国家和前苏联走过的工业化道路而具有明显的“中国特色” ,其思想的立足点就是全球信息技术革命背景下的中国国情。而这种具有“中国特色”工业化思想一直体现在建国以来的工业化道路探索之中。本文试从产业间关系、传统产业与现代产业间关系、科技与人才的作用、对外开放等几个方面对新型工业化所蕴涵的战略思想进行探析 ,得出这些思想具有很强的历史继承性的结论

Estimating the impact of incidents on urban controlled-access highways: an empirical analysis

An empirical analysis is developed that quantifies the impact of different types of traffic incidents on the speed and maximum flow averages of vehicles on a controlled-access highway. The incident types considered include damage to highway infrastructure, vehicle rollover, crashes (into stationary objects), collisions (with moving vehicles), rain, fog, vehicle breakdowns, pedestrians on roadway, etc. Using real-world data from Chile’s most heavily used urban motorway/freeway, estimates of incident impacts on speed are generated using a multiple linear regression model incorporating instrumental variables to correct for endogeneity. Flow results are then generated using the fundamental traffic equation relating speed, flow and density. A ranking of the impacts on highway traffic of the different incident types based on incident frequency as well as impact size demonstrates that for the real case studied, the incidents with the greatest cumulative effect are (in order of magnitude) vehicle breakdown, collisions and rain.

Supply chain and logistics innovations with the Belt and Road Initiative

The Belt and Road Initiative (BRI) is a massive, ambitious, long-term project initiated by the Chinese government, with participation from many other countries, to facilitate trade and improve logistics in an effort to promote global economic development. In this paper, we identified the supply chain and logistics innovations linked to the BRI. These innovations include new routes and modes for global trade, new supply chain design, reduction of cross-border logistics frictions, and entrepreneurial development. Examples of some of these innovations are emerging, while new ones are being developed. These innovations can enable businesses to improve their operational performances and create economic value. At the same time, to realize the full potentials of BRI, new work processes and technologies, incentive alignment, collaborations among businesses, and optimized planning are needed. This provides great opportunities for researchers to explore how to overcome barriers and achieve the full values of BRI.     

收费公路政策:“功臣”还是“罪人”?

通过对我国公路相关费用的估算,发现我国公路总投资相对于我们的估算来说,远低于我国公路相关费用。另外,贷款修路,收费还贷的方式已经成为我国高昂社会成本的推动力,中国高速公路的畸形发展恰恰是目前道路收费政策直接结果。此外,由于收费政策中的政府寻租,中国道路已经丧失了公共物品的属性,而沦为政府敛财的手段。     

Economics of upgrading gravel roads to Otta seal surface

Maintenance of low volume roads especially gravel roads is costly, and millions of funding annually are spent for aggregate replacement alone. Otta seal, compared to other bituminous surface treatments (BSTs) for low volume roads that require high-quality materials and specialized expertise, can be constructed using cheaper local aggregates and accessible equipment. However, only three states have reported Otta seal constructions and performance in the US. In this study, an economic analysis was conducted to compare the cost of maintaining a gravel road to the cost of upgrading an existing gravel road to a double Otta seal surface. This analysis was conducted at three levels: deterministic life-cycle cost analysis (LCCA), a stochastic Monte Carlo simulation-based LCCA, and a traffic based economic analysis. A generic one-mile rural road in Midwest was considered as a case study location. Although, according to the analysis conducted in this paper, an upgrade to Otta seal investment might be justified by maintenance savings, resorting to only such justification cannot warrant investment in most cases. The upgrade from gravel road to Otta seal, or any other BSTs, might be justified in terms of enhancing safety for road users and also encouraging economic development beneficial to local areas.     

丝绸之路沿线省区和国家发展定位分析——基于丝绸之路万里行实地考察视角

文章基于丝绸之路万里行实地考察的视角,分析了丝绸之路沿线陕西、甘肃、新疆等我国境内三省区和哈萨克斯坦、乌兹别克、俄罗斯、格鲁吉亚、土耳其、希腊、意大利等七个国家的发展定位。认为关天经济区是丝绸之路经济带新起点、甘肃是丝绸之路经济带黃金段、新疆是丝绸之路经济带核心区,哈萨克斯坦是丝绸之路经济带国际段桥头堡、乌兹别克是丝绸之路经济带中亚明珠、俄罗斯是丝绸之路经济带中亚到欧洲的桥梁、格鲁吉亚是丝绸之路经济带南北通道结合部、土耳其是丝绸之路经济带亚欧南通道、希腊是丝绸之路经济带陆海丝路交汇地、意大利是古丝绸之路的终点。通过分析并根据各省区和国家定位提出发展思路。     

走新型工业化道路 推动广西工业结构优化升级

目前,广西的工业发展面临巨大压力,经济总量不大主要是工业总量不大,经济竞争力不强主要是工业竞争能力弱,产业结构不优化主要是工业结构不合理,可持续发展能力弱主要是工业可持续发展能力弱。抓住了工业问题,就抓住了广西发展的关键。因此,必须走新型工业化道路。推动工业结构优化升级,解决我区工业落后、产业落后、经济落后的问题。     

黄石市区交通噪声污染变化分析

对1991～2000年黄石市交通噪声监测结果进行了分析。黄石市交通噪声污染源呈增加趋势。“九五”五年平均噪声值与“八五”五年平均噪声值相比较，质量好的路段长度增加2694米，占路段平均总长的8．2％，质量较好的路段长度增加7574米，占路段平均总长的13．2％，轻度污染的路段长度增加16165米，占路段平均总长的22．9％，中度污染的路段长度增加21468米，占路段平均总长的32．7％，重度污染的路段长度减少21045米，占路段平均总长的22．7％。黄石市道路交通噪声污染虽有缓解，但形势仍十分严峻，应通过严格执行行政管理措施、加强交通管理、加强道路平整度等措施解决交通噪声污染问题。
