中国数字经济的投入产出与产业关联分析

在新一轮科技革命的推动下,数字经济蓬勃发展,对经济社会影响重大。分析数字经济产业的投入产出结构及其产业关联特征,对于发挥数字经济的带动和支撑能力、推动中国经济增长及产业结构转型升级具有重要意义。本文使用2017年、2018年、2020年中国竞争型投入产出表对数字经济的投入产出结构和产业关联进行刻画,结果表明：第一,数字产业是传统制造业和服务业的重要中间投入和上游需求部门;第二,在产业静态关联方面,传统产业与数字产业的产业融合程度仍然较低,而数字产业对传统制造业和传统服务业的生产过程中均具有重要影响;第三,在产业动态联系上,数字制造业对国民经济各产业具有极强的需求拉动作用,但其他行业对数字产业的整体拉动作用较小。基于这些结论,本文为推动数字经济的发展提出了一些建议。     

集聚、研发要素流动与产业竞争力——以高端服务业为例

利用新经济地理学理论构建了高端服务业集聚、研发要素流动影响高端服务业竞争力的理论模型。理论分析表明,高端服务业竞争力与高端服务业集聚度、研发要素流动、劳动力数量、工业品支出份额正相关,与产品间替代弹性负相关。继而,利用中国31个省市自治区（因数据缺失,不包含港澳台地区）2003—2018年数据,空间探索性分析发现中国省域间高端服务业竞争力存在明显空间正自相关性。空间面板计量模型检验结果也很好地支持了理论模型的结论。表明高端服务业聚集度、R&D人员流动量和R&D资本流动量的提升正向促进高端服务业竞争力,但三者的总效应主要是由直接溢出效应决定的。本文结论为我国进一步促进高端服务业集聚,统筹区际间研发要素流动,进而提升中国高端服务业竞争力提供政策启示。     

员工股权激励对中小企业创新会产生补充的促进效应吗？

高管与核心技术员工作用于创新的不同过程,同时也是股权激励计划的主要激励对象,两者股权激励的互动效应对创新的影响值得探讨。选取2009—2015年成功实施股权激励的深A上市中小板与创业板公司为研究对象,考察员工股权激励对高管股权激励在中小企业创新中的影响及其作用机制。研究结果表明：实施股权激励计划能够显著增加企业研发投入与创新产出;相较于高管,核心技术员工股权激励强度越大,企业创新数量越多、质量越高;高管股权激励降低了创新转化效率。进一步地,融资支持效应和人才激励效应是员工股权激励补充促进创新的重要机制;代理成本在高管股权激励与研发投入关系中起遮掩作用。     

多元化并购、资源基础与制造企业服务化转型——基于fsQCA的多案例分析

为探究制造业企业通过并购实现服务化的转型路径,以2014—2018年制造企业并购服务企业并购事件为研究对象,运用组态思维和fsQCA方法,选取“基于并购的资源获取”和“并购后资源整合”两个维度的5个前因条件,讨论前因变量组合与制造业服务化转型之间的复杂因果机制。结果表明,制造业服务化转型存在3条转型路径,即研发能力驱动型、财务能力驱动型和服务化经验驱动型。通过分析路径和典型案例,发现：并购标的企业的盈利能力与研发能力均能衡量服务型资源质量且二者具有替代效应;并购方财务柔性在并购后整合与服务化转型中具有重要作用;并购方服务化经验有助于并购后整合。     

The sustainability of economic transformation

The paper analyzes the feasibility of sustaining both macroeconomic stability and political support during economic transformation. Macroeconomic stability requires that state sector losses plus public infrastructure investment be financed by tax revenue plus any external assistance. Political sustainability depends on the income gains and losses experienced by three groups—state sector workers, private sector workers, and private savers/investors. The aggregate income gains from allowing heterogeneous workers to make occupational choices consistent with their comparative advantages can outweigh or significantly offset the short-run economic efficiency costs of maintaining political support for the transformation. Successful transformation may depend on external assistance, but this need will diminish over time.     

A Multi-state model of state dependence in labor supply: Intertemporal labor supply effects of a shift from joint to individual taxation

In this paper I develop an intertemporal discrete choice model of female labor supply to analyze the effects of true state dependence and its effect on labor supply behavior over time. The estimation results show that state dependence is significantly positive at the extensive margin and lower but in general still significant at the intensive margin. I apply this model to study the short and long run labor supply effects of a fundamental reform of the German income tax system, i.e. the shift from joint to individual taxation of married couples and show that labor supply responses are significantly higher in the long run than in the short run.     

Border Effects Within A Dynamic Equilibrium Trade Model

A dynamic general equilibrium model is developed in which border effects are present. It is shown that despite very low trade barriers the presence of national borders can choke off a significant fraction of cross-border trade when firms experience start-up costs in establishing new markets. It is also revealed that country size, as measured by the number of markets in a country, can have a significant effect on how quickly firms grow. Also, it is shown that a decrease in trade barriers will increase the rate at which firms expand into both foreign and domestic markets. Furthermore, an increase in fixed costs at the production level is shown to increase trade flows. This helps explain why developed countries trade more than less developed countries. This article also develops a novel way to solve dynamic optimization problems when “state-space” constraints are present. The solution strategy is applicable to a wide variety of problems in which agents are not constrained now but are expected to be constrained in the future.     

Regional concentration of FDI in post-reform India: A district-level analysis

We analyze the concentration of foreign direct investment (FDI) in India at the district level, based on project-specific location choices since the reform program in the early 1990s. The decomposition property of the Theil index allows us to trace changes over time in the overall concentration of FDI to changes in concentration between and within subgroups of districts. We also differentiate between major types and sources of FDI. We find that FDI concentrated in a persistently decreasing number of districts. Concentration across those districts that received at least one FDI project within a given time interval also increased, but this increase leveled off in the more recent past. These trends hold for essentially all types and sources of FDI, while the average level of concentration varies considerably between these types and sources.     

RESPONSES OF ECONOMIC SYSTEMS TO ENVIRONMENTAL CHANGE: PAST EXPERIENCES

Current discussions of climate change are overly focused on the science underpinning environmental impact, with little attention to socioeconomic consequences. The economics of environmental change in particular is insufficiently informed by the lessons that past experiences can yield. Drawing on case studies from Europe and Asia, this special issue underlines the importance of historical context, as well as markets, institutions, technology, and the role of international trade in understanding how economic systems have responded to environmental changes. Past economies have responded dynamically to environmental change rather than simply constrained deterministically by the climatic and ecological events that have engulfed them.     

Happiness and Transition: the Case of Kyrgyzstan

The paper analyzes self-reported measures of satisfaction with life in a transition country, Kyrgyzstan, using 1993 household survey data. The authors test whether higher levels of satisfaction are associated with greater economic wellbeing. This hypothesis is strongly supported by the data. Unhappiness is prevalent among older people, the unemployed, and those who are divorced. There appears to be little correlation between happiness and either gender or education level. There is some evidence that income relativities, as measured by perceived position on the wealth ladder, also have a strong effect on life satisfaction.
