本文运用中国工业31个行业1998年-2004年的面板数据,分析了能源价格、FDI的进入程度、进出口商品结构、工业内部的行业结构和R&D投资强度对中国工业能源强度的影响。研究发现,能源价格的上涨对提高工业能源利用效率有显著的促进作用;降低FDI的进入程度与R&D投资强度都有助于降低工业特别是高能源强度行业的能源强度;降低高能源强度行业的出口额在工业出口总额中的比重,有利于降低高能源强度行业的能源强度,进口商品结构变化对工业能源强度没有显著影响;降低高能源强度行业的工业增加值在整个工业增加值中的比重,有助于降低全工业行业和低能源强度行业的能源强度。  相似文献

In this study we investigated the nature of disagreement, which is a necessary component of a good discussion. We obtained 27 group discussion scenes by Japanese undergraduates that were evaluated by two ways: impression rating and ranking. As a result of factor analysis for the impression rating data, five factors were extracted: activeness, multidirection and unification of discussion, relationships of participants, development and sophistication of discussion, and sincerity of the participants, and each factor scores of each scene was simultaneously calculated. Each scene’s rank score was also calculated by relative comparisons. A significant positive correlation was found between the mean factor and the rank scores except for Factor 3 (relationships of participants). To consider the reason for the difference relating to Factor 3’s score, we scrutinized the discussion process of four scenes of the different patterns of the factor and rank scores. From the analysis of conversations, we suggested that this difference reflected ways of disagreement. By introducing a probative discourse tags for discussion (pDTD), we reasoned that the frequency of disagreement made Factor 3’s score negative and the absence of the second part of adjacency pairs made the rank score worse. The explicit speech and actions of blame such as emotional and aggressive expression, and neglect of treatment for the minor opinion made also the discussion unfair, but we think that these behaviors might erupt from the ground made by the accumulated implicit behaviors such as the absence of the second part. We finally concluded that the criticism type of disagreement increased the rank scores, and its censure type produced lower results, and the proper ways of disagreement in group discussions were discussed.  相似文献

In this paper we study the relationship between women’s empowerment in agriculture and their iron deficiency status in Maharashtra, India. This is the first time the Women’s Empowerment in Agriculture Index (WEAI) has been used in association with explicit measurement of medical biomarkers for women’s iron deficiency status. Using primary data for 960 women we find that the log odds of a poor iron status in women decline as women’s empowerment levels in agriculture improve. Further, this decline is seen in the presence of multiple dietary diversity measures (dietary diversity score, share of rice and wheat in the diet, total iron intake and iron intake from iron-rich food groups – all for 24-h and 30-day recalls) suggesting that in addition to dietary pathways women’s empowerment can play a role in addressing micronutrient deficiencies like those of iron in a vulnerable sub-group of the population. It also reinforces the need to move away from the ‘staple grain fundamentalism’ that has characterized agricultural policy in India, towards more nutrition-sensitive food systems.  相似文献

陕北矿产资源富集区生态文明建设是一项系统工程。公众对生态环境的高度重视是生态文明建设的重要动力。调查数据表明:公众的生态理念有所树立,但不够深刻,在日常的商品消费中仍以关注商品本身为主,而为生态环境支付成本的意愿还有待提高。  相似文献

由于受封建思想的束缚。“男尊女卑”的观念深深扎根在人们的心里。从古至今,许多人都为女性解放而做出努力,可人们在女性解放的道路上却逐渐走向误区,盲目的追求男女的绝对平等。当代女性必须首先培养一个健全的自我意识,方可争取彻底的解放。  相似文献

Using new survey data from rural Kenya, this paper assesses the moderating effect of women’s empowerment on the relationship between agricultural technology adoption and women’s dietary diversity. We use a multiple treatment endogenous switching regression framework to control for potential endogeneity of women’s empowerment and technology adoption. We find that women’s empowerment has a positive and significant effect on the women’s dietary diversity score regardless of technology adoption status. We further show that women’s empowerment enhances the positive effects of technology adoption on women’s dietary diversity. Although technology adoption has a positive impact on women’s dietary diversity regardless of empowerment status, its effect is stronger for households with empowered vs. disempowered women. Study results suggest that individual and household welfare could be enhanced to a greater degree through interventions that promote women’s empowerment and technology adoption simultaneously rather than separately.  相似文献

资本资产定价模型(CAPM)在国际金融市场的实证检验结果往往呈现扁平证券市场线现象。一些学者认为融资限制是该现象的产生原因。本文旨在研究扁平证券市场线现象是否存在于中国股市,同时分析融资限制对中国股市证券市场线的影响。本文采用投资组合分析法对A股主板市场进行实证检验。本文研究发现:(1)扁平的证券市场线现象同样存在于中国股票市场中;(2)在中国股票市场中,融资限制与证券市场线的斜率呈负相关,与截距呈正相关,这符合融资限制理论;(3)以上两点发现同样存在于多因子定价模型中,这表明本文研究结果具有稳健性。    相似文献

Over the past decade, China’s outward foreign direct investment (OFDI) has rapidly increased. However, its characteristics are not sufficiently studied. In this article, we explore the host country’s determinants of China’s OFDI, with a focus on institutional quality, exchange rate volatility, and natural resources by performing an econometric analysis for the period 2003–2013 for a sample of 49 countries. Our results reveal that China’s OFDI is invested in countries with relatively poor institutional quality and abundant natural resources. Exchange rate variability has a dampening effect on China’s OFDI and that the appreciation of the Chinese renminbi enhances OFDI flows.  相似文献
