Energy conservation and CO2 emissions reduction in China's industrial sector is decisive for achieving a low-carbon transition. We analyze the change of energy-related CO2 emissions in China's industrial sector from 1991 to 2010 based on the Logarithmic Mean Divisia Index (LMDI) method. Results indicate that industrial activity is the major factor that contributes to the increase of industrial CO2 emissions while energy intensity is the major contributor to the decrease of CO2 emissions. Industry size shows a varying trend interchanging intervals of growth along the study period. Moreover, both energy mix and carbon intensity of energy use have negative effects on the increase of CO2 emissions. The cointegration method is adopted to further explore determinants of CO2 emissions in China's industrial sector. Results show that there exists a long-run relationship between industrial CO2 emissions and affecting factors such as CO2 emissions per unit of energy consumption, industrial value added, labor productivity and fossil fuel consumption. China's industrial CO2 emissions are mainly attributed to the coal-dominated energy structure. Policy suggestions are thus provided to reduce industrial CO2 emissions in China.The paper is supported by Newhuadu Business School Research Fund, Ministry of Education (Grant No. 10JBG013, 14YJC630026), Social Science Foundation (Grant No.12&ZD059) and National Natural Science Foundation of China (Grant No. 71472065)

    【Abstract】This paper employs a newly developed non-radial directional distance function to evaluate China's regional energy and CO2 emission performance for the period 1997–2009. Moreover, we analyze the impact of China's market-oriented reform on China's regional energy and carbon efficiency. The main findings are as follows. First, most of China's regions did not perform efficiently in energy use and CO2 emissions. Provinces in the east area generally performed better than those in the central and west areas.By contrast, provinces in the west area generally evidenced the lowest efficiency. Second, Market-or-iented reforms, especially the promotion of factor market, were found to have positive effect on the efficiency of energy use and CO2 emissions. Third, the share of coal in the total energy consumption and the expansion of the industrial sector were found to be negatively correlated with China's regional energy and CO2 emissions performance. Based on the empirical findings, we provide policy suggestions for enhancing energy and carbon efficiency in China.This paper is supported by the Research Fund of Newhuadu Business School, Ministry of Education Foundation (Funding no.10JZD0018), Basic Research Universities Special Foundation (Funding no.2010221051), Ministry of Education Foundation (Funding no. 10JBG013) and National Social Science Foundation (Funding no.09&ZD050).

    随着社会主义市场经济体系的不断完善,资本对企业并购重组的规模效应越发凸显。资本运作,作为一个有型的价值体系在商业运作中所起到的作用越来越值得重视。在这个过程中,企业的并购重组已经不再单纯的是资产整合问题,涉及到更多的是商业利益最大化的问题。伴随着并购重组所产生的巨大商业利益,税收,尤其是企业所得税,成为这一过程中的重要制度安排而显得愈发重要。在这样的背景下,本文结合资本运作中的实际情况,对资本市场中并购重组的企业所得税政策进行了相应研究,并结合沪深上市企业数据,对企业并购所得税政策对企业并购重组行为的影响进行了分析。 本文的主要内容分为三个部分:第一部分,结合我国企业所得税制度的发展过程,采...With the continuous improvement of the socialist market economic system, the scale effect of capital on mergers and acquisitions (M&A) has become increasingly prominent.

    根据盾构隧道的结构特点,用Qtech-413 粘弹阻尼材料对盾构管片标准块进行约束阻尼处理,通过单点锤击振动实验,得到处理前后结构的时域波形、固有频率、复合损耗因子等振动特性。实验结果显示:经过约束阻尼处理后,盾构管片振动加速度幅值降低了26.7%,振动时长降低了50%;各阶固有频率均有所降低,且随着频率的增加,降幅逐渐增加;各阶复合损耗因子均有所升高,高频增幅比低频增幅更大;振动总级值降低了10 dB 左右。因此,Qtech-413 粘弹阻尼材料应用于盾构隧道能降低振动加速度幅值、振动时间、固有频率和振动总级值,增加复合损耗因子,对高阶固有频率和复合损耗因子影响较大,低阶影响较小

    中文摘要自从1990年英国剑桥大学Cavendish实验室的Burroughes等人首次报道了聚对苯乙炔(PPV)的电致发光以来,这类材料逐渐步入了人们的视野,成为光电材料领域中最为活跃的研究方向之一,其中烷氧基取代对苯乙炔(PPV类)聚合物材料已成为该领域的研究热点。目前,从PPV类聚合物材料的研究进展来看,由于其合成、溶解性、发光效率、性能等方面尚存在一些问题,例如合成步骤冗长,产率低下,成本较高;溶解性较差,导致成膜性较差,不利于发光器件的制备;发光效率较低,发光波长无法控制等,这些方面的原因使其在光电领域的应用上受到了一定的限制。本论文首先从原料开始合成了制备聚合物的五种单体。在从二烷...ABSTRACTSince R.Friend and his group have reported the electroluminescence of Poly(p-phenylene vinylene) in 1990,these kinds of materials become favor to people rapidly.

    城市公共交通的发展为人们出行提供了更有效、更节能的交通方式,但是高效率的城市公共交通系统是否会有效地抑制车辆的能源消费,或者这一抑制效应到底有多大?这是在目前城市公共交通优先发展战略背景下需要明确的一个重要问题。本文试图从城市道路公交的角度,来分析城市道路公共交通的运行效率对城市车辆能源消费的抑制效应。本文利用中国36个中心城市2010—2015年的道路公交运营数据,结合非径向方向距离函数(NDDF)的方法,对不同城市的公交车和出租车的运行效率进行评价。在此基础上,对城市道路公共交通的运行效率对车辆能源消费的抑制效应进行分析。本文还利用IV-GMM方法处理内生性问题,以得到更为合理的估计结果。最后,利用面板门限模型对收入效应带来的影响进行了深入讨论。国家社会科学基金重点项目(No.17AZD013)的支
