我国区位优势对制造业集聚影响的实证研究

对我国29个省(自治区、直辖市)的区位优势和20个制造业细分行业的集聚水平进行了测算,采用系统广义矩估计方法实证分析了区位优势对制造业集聚的影响。结果表明:区位优势与制造业各行业的集聚程度显著相关:大多数现代制造业和依赖规模经济的制造业与区位优势正相关,大部分传统制造业与区位优势负相关;不同的制造业细分行业侧重不同方面的区位优势。     

价值链视角下科技人才分布对区域创新系统效率的影响

科技人才作为科技创新的主体,是区域创新系统的重要投入,其省际分布状况潜在影响着各区域创新效率。基于2009-2016年我国内地30个省级区域科技人才与研发面板数据,在创新价值链分解的基础上,分别考察科技人才数量与结构维度对区域创新系统三阶段效率的影响。结果发现：在数量维度下,科技人才分布规模对区域知识创新效率、专利创新效率有非线性倒U型影响,先后从人才聚集规模经济效应转向不经济效应;整体集中度提高即全国科技人才分布相对集中有助于提升各地区专利创新与产品创新效率;在结构维度下,科技人才队伍中女性与博士研发人员越来越高的比重对知识创新效率表现为负向影响作用。最后,结合新旧动能转换背景,提出积极发挥人才集聚正向效应的建议。inno[]rlzb[]rlzb[]czpz[]czpz[]cyjg[]cyjg[]dwkf[]dwkf〖BHDG1*3,WK7*3ZQ,WK6。9DWW〗     

以社会主义核心价值观引领高校基层党组织建设与创新

社会主义核心价值观是“以人为本”的价值观,是建设和谐社会的根本,为社会主义事业指明了方向。高校的创新精神和能力决定着国家的前途,当前高校基层党建中存在一些问题,是与发挥党组织的先锋堡垒作用相背离的,创新高校党建工作机制,是坚持社会主义办学方向的重要保证。本文阐述了高校要以社会主义核心价值观引领基层党组织工作的创新的意义和途径,提出基本思路,并进行有益的实践和探索。     

Can the affordable care act provisions explain the recent wave of acquisitions in the health insurance industry?

This research shows that the ACA health insurance exchanges have generated more merger activity in the health insurance market. The impact is robust to control for an extensive set of factors suggested by both neoclassical and behavioural frameworks. The economic impact of this ACA provision is substantial with 3.8 more months of unusually high merger activity or 52 more merger bids per year.     

Rational inattention,long-run consumption risk,and portfolio choice

This paper explores how the introduction of rational inattention (RI) – that agents process information subject to finite channel capacity – affects optimal consumption and investment decisions in an otherwise standard intertemporal model of portfolio choice. We first explicitly derive optimal consumption and portfolio rules under RI and then show that introducing RI reduces the optimal share of savings invested in the risky asset because inattentive investors face greater long-run consumption risk. We also show that the investment horizon matters for portfolio allocation in the presence of RI, even if investment opportunities are constant and the utility function of investors is constant relative risk aversion. Second, after aggregating across investors, we show that introducing RI can better explain the observed joint dynamics of aggregate consumption and the equity return. Finally, we show that RI increases the implied equity premium because investors under RI face greater long-run consumption risk and thus require higher compensation in equilibrium.     

Real exchange rates,asset prices and terms of trade: A theoretical analysis

This paper develops a continuous-time two-country dynamic equilibrium model, in which the real exchange rates, asset prices, and terms of trade are jointly determined in the presence of nontradable goods. The model determines the relation between the financial markets and real goods markets in the world economy and their responses to various shocks under the home bias assumption. A positive domestic supply shock induces a positive return on the domestic asset markets and a deterioration of terms of trade that improves the foreign output and boosts the foreign asset markets. Demand shocks act in the opposite way. This model also analyses the impact of change in the relative price of nontradable to tradable goods on the terms of trade and asset markets. A higher productivity growth in tradable goods than in nontradable goods leads to a higher relative price of nontradable to tradable goods, which appreciates the real exchange rate, deteriorates the terms of trade, and depresses the domestic and foreign asset markets. A lower relative price of nontradable goods depreciates the real exchange rate, improves the terms of trade, and lifts both the domestic and foreign asset markets.
