互联网发展与区域创新能力非线性关系研究

党的十九大报告要求全力推动互联网、大数据、人工智能与实体经济深度融合。在此背景下，明晰互联网与区域创新能力关系至关重要。基于2006-2017年中国内地30个省区市面板数据，运用门槛面板回归技术，全面探讨了互联网发展与区域创新能力间的非线性关系。研究结果表明：互联网发展对区域创新能力存在边际报酬递增的正向非线性影响，且在政府支持环境下两者存在正向、边际报酬递增的非线性关系，但在对外开放环境下，两者存在正向U型关系。进一步研究发现，互联网发展对不同创新主体的创新能力存在异质性双门槛效应，如对高校、企业呈现出正向U型影响，而对研发机构表现为正向的边际效率递减规律。依据该结论提出具有针对性的差异化“互联网+创新能力”融合策略。     

创新网络领域知识主题研究述评

在知识经济时代，创新网络在企业创新中扮演着重要角色，而研究网络中知识要素的产生、传播、吸收等问题对了解企业网络化创新具有重要意义。基于国内外核心文献数据库，收集创新网络领域知识要素相关文献，并结合文献计量分析方法，对该领域近30年有关知识主题研究的演化规律、整体趋势等进行梳理。结果表明，国内外研究年度发文量均呈现3个阶段变化趋势，且分别拥有各自重要载文期刊，国内研究已形成核心团队，而国外并未形成；国内外研究既有相同之处，也存在差异性，且均形成较为清晰的研究框架；在演化规律上，国内横向拓展和纵向深化研究特征显著，而国外更加注重纵向深入探索分析，研究内容也更加分散；在未来前沿热点分析上，中外学者关注内容既有相同点，也有不同点，知识协同、知识惯例、企业数字化转型对知识影响的研究是未来关注重点。

Boxing and Martial Arts Company,A Tax Case

A tax case is developed examining a private Canadian sports company. This case simulates a real‐world start‐up company in the area of Canadian Controlled Private Corporation taxation. The client, Boxing and Martial Arts Co., is a medium‐sized, rapidly growing sports promotion business. It operates in an environment where cash payments are common, especially towards foreign workers. Students must research issues involving tax deductions and revenue recognition. The learning objectives include: reinforcing taxation concepts that most students learn in introductory courses (i.e., revenue recognition, allowable business expenses) as well as improving students’ tax research skills for more complex issues (e.g., international tax treaties).     

入世后我国主要贸易税收政策功能调整的定位分析

入世后,我国贸易税收政策的功能必须在经济全球化的背景下制定和调整。本文通过分析关税、出口退税、反倾销税三大贸易税收政策的主要功能在内、外部因素的影响下发生的变化,提出了我国入世后贸易税收政策功能调整的战略方向及措施:应强化关税产业保护功能,弱化财政收入功能;应以“走出去”战略为依据,真正发挥出口退税制度的保护产业和鼓励出口的基本功能;应发挥经济比较优势,加强国际分工合作,避免反倾销税成为过度产业保护的工具。

GOVERNMENT SIZE AND GROWTH: A SURVEY AND INTERPRETATION OF THE EVIDENCE

Abstract The literature on the relationship between the size of government and economic growth is full of seemingly contradictory findings. This conflict is largely explained by variations in definitions and the countries studied. An alternative approach – of limiting the focus to studies of the relationship in rich countries, measuring government size as total taxes or total expenditure relative to GDP and relying on panel data estimations with variation over time – reveals a more consistent picture. The most recent studies find a significant negative correlation: an increase in government size by 10 percentage points is associated with a 0.5% to 1% lower annual growth rate. We discuss efforts to make sense of this correlation, and note several pitfalls involved in giving it a causal interpretation. Against this background, we discuss two explanations of why several countries with high taxes seem able to enjoy above average growth. One hypothesis is that countries with higher social trust levels are able to develop larger government sectors without harming the economy. Another explanation is that countries with large governments compensate for high taxes and spending by implementing market‐friendly policies in other areas. Both explanations are supported by ongoing research.     

GOVERNMENT SIZE AND GROWTH: A REJOINDER

In our 2011 survey of the literature in the Journal of Economic Surveys on the effect of government size on economic growth in wealthy countries we find a relatively consistent pattern: An increase in government size by 10 percentage points is associated with a 0.5–1 percentage point lower annual growth rate. This conclusion is questioned by Colombier. In this rejoinder we present a rebuttal of Colombier's argument based on a detailed scrutiny of his own statistical evidence and regression results. Furthermore, we note that several new papers that have appeared since our original paper was published give support to our main conclusion.     

Is corporate payout taxation a long run phenomenon? Evidence from international data

This paper examines whether dividend and capital gains taxation influences corporate payout policy using the country level data of 21 countries in panel versions of time series models. We find that dividend relative to capital gains tax penalty is cointegrated with corporate payouts (dividends and share repurchases) i.e. corporate payout taxation may be a long run phenomenon. Further, the cointegrating vector estimates are largely consistent with the traditional view of dividend taxation whereby the tax penalty discourages dividends, while the estimates give limited support to the premise that firms substitute dividends for share repurchases in response to an increase in dividend tax penalty. Long run causality also operates between the tax penalty and payouts in the error correction models. Additionally, dividend tax appears to be more influential than capital gains tax on dividend payout decisions. Lastly, taxation affects dividends more significantly in countries with high investor protection.
