基于价值链视角的高技术产业用地效率变化研究 ——以浙江省为例

研究目的：从价值链视角分析高技术产业用地效率时空变化特征,为提升高技术产业用地效率、促进产业转型升级及推动经济高质量发展提供理论依据。研究方法：DEA-Malmquist指数模型法。研究结果：（1）从价值链整体来看,2014—2016年浙江省整体高技术产业用地效率呈现增长的趋势,且全要素生产率改善上升了9.8%。（2）从价值链分阶段来看,若调整投入要素数量及结构,浙江省高技术产业用地可节约679.78 hm2,约占全省高技术产业用地面积的5.56%。在产出阶段,全省中间成果产出向最终成果产出的转化效率较低。（3）从价值链的时空变化来看：在时间变化上,2014—2016年整体用地效率呈先升后降状态;在空间布局上,2014—2015年呈西北向东南递减的趋势,2015—2016年表现为南北高、中间低的态势。研究结论：总体用地效率提高主要得益于技术进步和规模效率变化,成果转化率不高关键在于技术效率偏低,而提升整个产业链的用地效率主要是如何降低土地要素投入冗余,因此,针对价值链全阶段,提出调整初始投入的规模和结构、加快中间成果的技术转化率、优化最终成果的时空布局等建议。     

投资者情绪与沪深300股指期货定价偏差关系研究

股指期货已发展成为全球金融衍生品主流品种,股指期货定价问题事关市场套利行为,一直备受投资者关注。本文基于投资者情绪视角,运用VAR模型、脉冲响应、方差分解等方法,深入探讨沪深300股指期货定价偏差与投资者情绪的关系。研究发现:投资者情绪与沪深300股指期货定价偏差之间构成因果关系,且呈现正向影响;股指期货定价偏差受投资者情绪影响而长期存在,其对投资者情绪的影响短期效果显著。     

比较优势动态转换与产业升级——基于中国制造业发展指标的国际比较

通过对国内外比较优势与产业升级理论的梳理,创新性地将其概括为比较优势动态转换的三条途径与产业升级的四个维度,并将二者结合起来,构建中国制造业比较优势动态转换与产业升级的理论框架,对中国制造业发展指标进行国际比较研究,得到如下结论:从垂直结构升级考察,中国制造业呈现全方位崛起的态势,完成了从低端产业向高端产业的升级;从水平结构升级考察,依据进口中间品国内配套增值率指数测算,中国制造业国内集成配套能力较强,但依据进出口中间品增值率指数测算,中国制造业在全球价值链中分工地位较低;从产业效率考察,中国制造业技术效率世界领先;而全要素生产率及其分解显示,中国制造业技术进步水平还存在较大的差距;从产业效益考察,中国制造业增加值率低下,但作为增加值构成要素的税收占比很高,中国制造业出口占总产值比重在世界排序较低,中国内需市场潜力巨大。     

‘Globesity’? The effects of globalization on obesity and caloric intake

We examine the effect of globalization, in its economic and social dimensions, on obesity and caloric intake, namely the so –called ‘globesity’ hypothesis. Our results suggest a robust association between globalization and both obesity and caloric intake. A one standard deviation increase in globalization is associated with a 23.8 percent increase in obese population and a 4.3 percent rise in calorie intake. The effect remains statistically significant even after using an instrumental variable strategy to correct for some possible reverse causality and ommited variable bias, a lagged structure, and corrections for panel standard errors. However, we find that the primary driver (of the ‘globesity’ phenomenon) is the ‘social’ rather than the ‘economic’ dimension of globalization, and specifically the effect of changes in ‘information flows’ and ‘social proximity’ on obesity. A one standard deviation increase in social globalization increased the percentage of obese population by 13.7 percent.     

Monetary and Financial Cooperation Between China and the One Belt One Road Countries

ABSTRACT

Based on the theory of optimal currency area (OCA), we calculate the OCA index between China and the OBOR partners with the expressed objective of identifying which partners exhibit monetary and financial compatibilities, and hence present the best potential in terms of cost and benefits. Our findings suggest that among South East Asia region, Malaysia exhibits the highest compatibility and profit potential, followed by Thailand and Vietnam. For the East European area, Poland and Croatia show the best potential in terms of monetary and financial cooperation; with the Czech Republic as close third. Based on our computation, currently Central Asia and the Middle East do not possess the condition or potential for beneficial financial and monetary collaboration.     

Diversification and sophistication of livestock products: The case of African countries

This study assesses the level of sophistication of livestock products in Africa by evaluating technology intensity and economic complexity of each product. Using trade data from 1995 to 2012, livestock commodity exports are classified based on technology intensity. Employing a method of reflection in computing the economic complexity of export products, we find that one fifth of African livestock commodity exports are manufactured with low technology while the rest is composed of raw materials. The results also show that the ten most complex livestock commodities represent about a third of African livestock total exports while the world level is almost double this figure. Yet African countries spend a huge share of their wealth on importing complex products. The results imply that by exporting non-complex products Africa loses nearly a third of the total value of its livestock exports. To boost the value of livestock products, African countries should exploit their untapped potential while securing the domestic market to achieve import substitution. This can be done by integrating with global value chains or developing niche markets at the regional or international markets and improving productive capabilities.     

Towards the Development of a Tax System Complexity Index

Reducing tax system complexity is a common goal amongst policymakers; yet there is no commonly agreed definition of complexity. This paper seeks to fill this gap, by proposing the construction of an index of tax system complexity, conceived as a summary indicator of the overall complexity of a tax system at a particular point in time. If adopted, such an index would not only enable assessment of the changing level of a country's tax system complexity over time, but may also facilitate comparisons of the relative complexity of different countries' tax systems in future.     

The information compliance indexes. The illustrative case of income taxes

The adoption of IASB’s standards has represented, in the European Union, an important effort of harmonization towards the financial reporting comprehensiveness, reliability, relevance and comparability. This paper seeks to highlight the importance of Information Compliance Indexes (ICI), based on the accounting standards, as a proxy for reporting quality awareness. This approach is evidenced through an illustrative example about disclosures on deferred taxes, as required by IAS 12. This standard prescribes the accounting treatment for current taxes, deferred assets and liabilities. These issues are usually perceived by stakeholders as indicators of companies’ continuity and potential future returns. Based on non-financial listed companies of Euronext Lisbon regulated market, with reference to the end of fiscal years 2008 and 2012, an information compliance index was performed, based on that accounting standard. Then, this index was regressed with a set of performance and control indicators. Evidences have provided several statistical significant insights, which corroborate the findings that information compliance and disclosure levels depend from several performance and control indicators.
