关于《钢铁行业生产经营规范条件》(工原[2010]第105号)的博弈研究

我国钢铁行业近年来一直面临产能过快增长、布局不合理、铁矿石流通秩序混乱和资源环保压力大等问题,为了促进这些问题得到解决,国家工业和信息化部于2010年6月出台了《钢铁行业生产经营规范条件》。本文从涉及该规范条件执行的中央、地方和钢企三方利益博弈的角度进行分析,指出博弈各方从自身成本收益角度可能采取的策略选择和行动,并最终对该规范条件的执行效果产生影响。最后,结合博弈研究推导的结果与当前政策执行的现实困境,本文提出了相关的政策建议。     

基于多元技术会聚的会聚影响力研究

近年来,知识体系间呈现交叉、融合发展态势,技术会聚对创新发展的影响日益加深,应对这一态势的关键在于把握技术会聚的核心技术领域。多领域交叉关系是当前技术会聚研究重点,以此为视角,以专利分类代码信息为研究对象,采用关联算法探测领域间的会聚关系,建立多元交叉影响关系测度模型,并引入特征向量中心度指标测度领域会聚影响力。运用以上构建方法,对生物技术领域相关专利进行实证分析,从而验证方法的可行性。     

新时期西南民族地区农业外向化“五位一体”推进路径探析——基于跨境农产品供应链的视角

目的/意义随着西南民族地区农业外向化的深入发展,跨境农产品供应链的兴起、嵌入及其引领作用的发挥成为一种客观需要和逻辑必然。方法/过程在西南民族地区农业外向化进程中,农户“点”、核心企业“点”、跨境农产品供应链“线”、西南民族地区农业“面”及农业外向化资源有机集合“体”等跨境农产品供应链(联盟)关键要素,既是农业外向化发展的重要动力来源,也是递进的协作主体或资源。本文从理论层面和实践层面对此进行了梳理。结果/结论跨境农产品供应链“五位一体”推进西南民族地区农业外向化的改革探索,一方面需要厘清跨境农产品供应链“五位一体”推进农业外向化的依据,另一方面需要建构跨境农产品供应链“五位一体”务实推进农业外向化的路径。     

基于PCA-DEA综合评价模型的大中型工业企业技术创新效率评价

为克服DEA方法的弊端———指标集增大导致决策单元的有效性系数增大,采用主成分分析与DEA相结合的综合评价模型,对2011年我国31个省(自治区、直辖市)大中型工业企业的技术创新效率进行了综合评价,并分析了产生不同评价结果的原因以及需要调整的方向。结果表明:当前我国各地区大中型工业企业整体的技术创新效率不高,各地区的大中型工业企业普遍存在创新投入不足的问题;各地区的大中型工业企业的技术创新效率存在显著差异。最后,提出提高技术创新效率的建议。     

中国温室气体减排成本有效性分析——以纯电动汽车为例

从减排成本有效性的角度,研究了纯电动汽车的碳排放和减排成本的特性及其相互关系,对纯电动汽车减排成本的关键影响因素进行了敏感性分析。结果显示:在现有的技术条件下,纯电动汽车的减排成本较高,在万元每吨数量级上;纯电动汽车的减排成本随着其电池容量的加大而增加;减排成本受多方面因素的影响,有较大的下降潜力;当电池成本下降到2000元/kW·h以下或汽油价格高于11元/L时,纯电动汽车可以实现减排成本为负,此时发展纯电动汽车是极具竞争力的减排手段。     

The use of limited dependent variable techniques in strategy research: issues and methods

Strategy researchers are increasingly turning their attention from examining the impact of strategic choices on firm performance to examining the factors that determine strategic choices at the firm level. This shift of research orientation has meant that researchers are increasingly faced with a limited dependent variable (LDV) that takes a limited number of usually discrete values, for which LDV methods such as logit or probit are required. Despite their growing popularity, there appears to be widespread problems in the use of LDV methods. This research note complements recent studies that offer general guidelines by presenting and illustrating the practical steps needed to implement the methods essential for analyzing and interpreting the results from LDV models.

Transparency for Sponsored Content: Analysing Codes of Ethics in Public Relations,Marketing, Advertising and Journalism

As sponsored content is gaining ground globally, the boundaries between strategic communication, advertising and journalism are blurring. As sponsored content becomes more common, it raises novel ethical concerns that no industry alone can answer, such as How much disclosure is needed for transparency? Self-regulation via codes of ethics has been suggested as a remedy to meet the rising transparency expectations, and this article analysed 40 codes of ethics in the fields of communication, advertising, and journalism (United States and Finland) related to sponsored content. The results indicate that there remains excessive variation within the codes of ethics of how transparency of sponsored content is addressed. According to our analysis, most of the codes deal with transparency and the separation between commercial and editorial content only vaguely, and only eight of the total 40 guidelines take sponsored content into account. Therefore, we believe that the strategic benefit of sponsored content is threatened as long as no joint codes of ethics exist for sponsored content. To the degree that sponsored content is practiced across professions, we call for a joint code of ethics for sponsored content transparency, as the current codes of ethics fail to answer this emerging need.     

Pairs trading in the UK equity market: risk and return

In this paper, we provide the first comprehensive UK evidence on the profitability of the pairs trading strategy. Evidence suggests that the strategy performs well in crisis periods, so we control for both risk and liquidity to assess performance. To evaluate the effect of market frictions on the strategy, we use several estimates of transaction costs. We also present evidence on the performance of the strategy in different economic and market states. Our results show that pairs trading portfolios typically have little exposure to known equity risk factors such as market, size, value, momentum and reversal. However, a model controlling for risk and liquidity explains a far larger proportion of returns. Incorporating different assumptions about bid-ask spreads leads to reductions in performance estimates. When we allow for time-varying risk exposures, conditioned on the contemporaneous equity market return, risk-adjusted returns are generally not significantly different from zero.
