皖江城市带承接产业转移集中区建设之思考

当前,两大省管集中区建设虽然取得了一定成效,但仍面临若干挑战,尤其是产业发展定位、农民利益保护、技术人才短缺、融资及管理体制不活等诸多问题,需要通过统一规划、错位发展,因地制宜、协调发展,引进人才、合作发展,用活政策、创新发展,完善体制、稳步发展等措施来进一步解决。     

Impact of trade cost on China-EU agri-food trade

In this research, we investigate trade costs in relation to China-EU trade in agri-food products during 2001–2015. Major components of trade cost include transportation costs, border-related policy barriers such as tariffs, and local distribution costs. Our results indicate that trade costs between China and EU involving agri-food products, although falling, remain abnormally high. Consequently, we find that trade cost reductions contribute to over half of the overall China-EU trade growth. Our decomposition technique demonstrates that economic growth and trade cost reductions are the key drivers of China-EU trade expansion. Implementation of the Belt and Road Initiative (BRI) would reduce high trade costs to increase EU-China bilateral agricultural trade significantly. This is not fully captured in the gravity models where a static distance is usually used as a proxy to trade cost. The BRI will not reduce the distance, but it will cut transportation and other components of trade cost for China-EU trade.     

新型全密封多点受料带式输送机导料槽

一种应用于散粮输送的全密封多点受料带式输送机的新型导料槽。此种新型导料槽有便于调节、缓冲、挡料、拢料和便于检修等优点。新型导料槽可调节粮食下落到运行皮带上的粮流方向与进料落点,可对筒仓出料的粮食起导向和缓冲作用,可有效缓解对皮带的冲击,提高粮食在皮带上的成形稳定性,减少输送机在受料点出现跑偏与撒料情况的发生。     

新常态下辽宁沿海经济带对外开放程度测算——基于与沈阳经济区比较视角

以厘清新常态的本质作为切入点,基于外贸依存度、出口依存度、进口依存度以及外资依存度等视角对新常态下辽宁沿海经济带对外开放程度进行测算,并与同为国家区域经济发展战略试验区的沈阳经济区进行比较。测算与比较的结果为辽宁沿海经济带在未来进一步扩大对外开放的进程中更为精确地找准定位和明确发展思路提供新鲜而又客观的经验分析与丰富的数据支撑。     

滤棒固化库输送系统的改造

滤棒固化库（以下简称滤棒库）实现对滤棒的储存、固化和输送功能。目前，由于皮带输送机的设计缺陷，造成滤棒盒输送不稳。滤棒库堆垛机在运行过程中，故障次数多、维护时间长、运行效率低。因此，对皮带输送机间的过渡连接、导向护栏进行改进，并对电控程序进行优化，改造后滤棒库的堆垛机故障次数降低了79％。通过输送系统的改造，能有效保证滤棒的储存和输送，保证了车间生产的正常进行。

Abstract

Seat belt use does not only save lives but prevents the severity of injuries in road traffic crashes (RTCs). Vehicle type and usage have been found to influence the use of seat belt in cities like Kumasi, the host of Kwame Nkrumah University of Science and Technology (KNUST) campus. This paper presents a study on an un-obstructive survey of seat belt use by vehicle occupants entering and leaving KNUST campus through the four entrances from 7 to 9 am and 3 to 5?pm on five weekdays. A total of 5489 vehicles with 9542 occupants comprising 5489 drivers, front-right and first back seat and second back seat passengers were observed. The majority of the private and SUV drivers used seat belts. Meanwhile, almost all the commercial drivers did not use seat belts. There is a statistically significant relationship between vehicle type and use and the use of seat belt in KNUST.

Trade development between China and countries along the Belt and Road: A spatial econometric analysis based on trade competitiveness and complementarity

This paper empirically analyses the effect of trade competitiveness and complementarity on the trade development between China and the countries along the Belt and Road (B&R). The study first measures the trade competitiveness and the complementarity between China and the countries along the B&R by using the trade competitiveness coefficient (TCC) and the trade complementarity index (TCI). Then a spatial gravity model is constructed to analyse the effect of trade competitiveness and complementarity on trade development between China and the countries along the B&R. We use generalized method of moments (GMM) and spatial filtering technology to verify the robustness of the model. The results show that the GDP of China and the countries along the B&R, the land area of countries along the B&R, trade complementarity, common language, free trade agreements (FTA), and the B&R Initiative significantly promote the trade development between China and the countries along the B&R, whereas the geographical distance between countries and trade competitiveness significantly inhibit it. Finally, to promote the trade development between China and the countries along the B&R, the present paper puts forward suggestions including improving trade promotion policies between China and the countries along the B&R and vigorously expanding cooperation with complementary industries in the countries along the B&R to enhance trade dependence.
