区域碳排放强度变化的因素分解模型及实证分析——以江苏省为例

文章通过分解模型从横向和纵向两个方面分析影响碳排放强度变化的因素.研究表明,江苏省碳排放强度变动由行业碳排放强度和行业产出份额共同作用.相对于行业产出份额,行业碳排放强度对整个社会碳排放强度变动影响更大.而工业行业对整个社会碳排放强度贡献较大,工业部门内部结构变化对碳排放强度变化有较大影响.因此,江苏省碳排放强度研究应该重点放在行业碳排放强度的变化,尤其是研究工业行业碳排放强度的变化上以及工业结构的调整上.     

中国工业行业能源强度影响因素的实证分析

利用中国31个工业行业1998—2004年面板数据,采用分层聚类方法,按年平均能源强度将31个工业行业分为高能源强度行业和低能源强度行业,并对全工业行业、高能源强度行业和低能源强度行业能源强度的影响因素进行了实证分析。研究结果表明,能源价格上涨对提高工业行业的能源利用效率有显著的促进作用;FDI进入程度的增大提高了工业行业尤其是高能源强度行业的能源强度;进、出口商品结构变化对工业行业能源强度没有显著影响;工业内部的行业结构变化对全工业行业和低能源强度行业的能源强度有显著负的影响,对高能源强度行业没有显著影响;R&D投资强度的增加提高了工业行业特别是高能源强度行业的能源强度。     

开放条件下中国工业能源强度的影响因素分析——基于31个行业面板数据的实证分析

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。

广告设计中的色彩应用

色彩是构成广告的重要因素,一幅成功的广告必然是色彩运用搭配得最好、最合理的广告。因此,作为设计者要想灵活地应用色彩,发挥好色彩的作用,就需要对色彩与心理的一般关系、广告色彩的作用、色彩在广告应用中的特性等方面进行深入研究,提高运用色彩的能力。     

高收入国家与中等收入国家的能源密度差异的实证研究

本文依据1990年至2000年间中国和11个OECD国家的14个工业产业的样本数据,运用可乘对数的Divisia指数分解方法,实证分析了这些国家的能源密度变化特性,解释推动能源密度变化的主要因素。实证分析结果显示,所有中等收入国家在这期间都经历GDP的快速增长和能源密度的迅速下降。尽管能源密度降低速度较快,但是从总体水平上看,中等收入国家的能源密度同高收入国家还存在较大的差距。另外,无论是中等收入国家还是高收入国家,纯密度变化都是能源密度降低的最主要原因。而且中等收入国家的能源使用效率的提高与经济开放、工业私有化和市场自由化过程相关。     

激励性规制的强度分析

网络型产业中存在的信息不对称使规制契约的存在成为必然。现实经济活动中之所以要设计和采用不同强度的激励性规制,主要是由于没有哪种规制机制能够解决所有问题。在理论综述的基础上,借鉴前人的研究,分析了网络型产业的激励性规制模型中的激励强度与激励绩效的关系,并指出其在实践中的应用以及对我国的借鉴。     

Mediated communication of ‘sustainable consumption’ in the alternative media: a case study exploring a message framing strategy

In view of previous effects of mediated communication on public knowledge, perceptions and concern about sustainability problems, this case study explores a message framing strategy for improving the effectiveness of mediated communication of the somewhat neglected topic of sustainable consumption. It describes how an information campaign on sustainable consumption was strategically framed, employing theories on effective and persuasive communication, and implemented through a community news medium in Christchurch, New Zealand. The resultant impacts of the campaign (significant increases in understanding of sustainable consumption and in the number of parents expressing concern over advertising effects on their children's material desires) were indicative of the potentials of employing strategic message framing for improving mediated communication about sustainability. The study also illustrates the potentials for engaging alternative media in such communication. This paper argues that further steps to develop message framing strategies for mediated communication of sustainable consumption is necessary, as this appears to be a largely neglected area in communication and consumer studies, and concludes with an overview of aspects that may be considered in future communication and other initiatives promoting sustainable consumption as a means for achieving sustainability.     

The role of inventories and capacity utilization as shock absorbers

We examine the role of inventories and capacity utilization (of both capital and labor) for the propagation of business cycle fluctuations. We document a new set of facts regarding the U.S. cyclical regularities of inventories and capacity utilization. First, we find that capital utilization and the flows of services from both capital and labor are procyclical, and comove with the holdings of inventories. Second, we find that labor utilization is procyclical as well, but is weakly negatively correlated with inventories. We build a model that accounts for these facts, and also accounts for the stylized inventory facts, i.e., inventory holdings are procyclical, while the inventory-to-sales ratio is countercyclical. The analysis is centered on the effects of two possible shocks: preference (demand) shocks and technology shocks. Our model shows that inventories and the rate of capital utilization are mostly complements, while inventories and the rate of labor utilization are mostly substitutes. It further shows that temporary demand shocks emphasize the role of inventories as being a “shock absorber,” whereas high-persistence demand shocks, as well as technology shocks of any persistence, emphasize the role of inventories as being a complement to consumption.     

广告促动经济发展

广告是市场经济的产物,在经济环境不断变化的大背景下发展、成熟。广告与经济相辅相成,相互促进。本文从广告与经济的关系着眼,在对二者关系进行分析的基础上,指出了我国经济发展中的问题之一即我国企业的广告投放量明显不足,同时就当前的世界经济情况下企业广告的投放提出了科学、合理的建议。
