河北省产业承接的技术溢出效应研究

京津冀协同发展战略上升为国家战略,河北加快承接京津产业转移的步伐,对河北经济转型升级和科技创新能力提升具有重要意义。以河北省为研究对象,基于2005-2016年的数据,使用DEA的曼奎斯特指数方法测算出河北省十二年的技术进步变化情况,并以此为核心变量建立技术溢出模型实证检验了产业承接的技术溢出效应。研究结果发现,河北存在承接区际产业的技术溢出效应,但FDI的技术溢出效应并不显著;R&D经费投入对河北技术进步的促进作用最为明显,而人力资本投入对技术进步的拉升作用较小。     

Public Sector Employment and the Skill Premium: Sweden versus the United States 1970–2012

Swedish census data and tax records reveal an astonishing decline in the aggregate skill premium of 30 percent between 1970 and 1990, with only a modest recovery in the next couple of decades. In contrast, the US skill premium rose by around 24 percent over those four decades. A theory that equalizes wages with marginal products can rationalize these disparate outcomes when we replace commonly used measures of total labor supplies by private sector employment. The dramatic decline in the skill premium in Sweden is the result of an expanding public sector that has disproportionately hired unskilled labor.     

When fund management skill is more valuable?

Does fund management skill allow managers to identify mispriced securities more accurately and thereby make better portfolio choices resulting in superior fund performance when noise trading – a natural setting to detect skill – is more prevalent? We find skilled fund managers with superior past performance to generate persistent excess risk‐adjusted returns and experience significant capital inflows, especially in high sentiment times, high stock dispersion, and economic expansion states when price signals are noisier. This pattern persists after we control for lucky bias, using the ‘false discovery rate’ approach, which permits disentangling manager ‘skill’ from ‘luck.’     

Foreign direct investment and inequality: Evidence from China's policy change

In this paper, we examine the impact of foreign direct investment (FDI) on local urban inequality in China. Specifically, we consider the FDI policy change as an exogenous shock on the local labour markets. We find that cities that have experienced a bigger policy change in promoting FDI between 1997 and 2002 are significantly more unequal in 2005. This pattern is mainly driven by the positive association between FDI liberalisation and skill premia. The result holds after we control for other policy changes, such as privatisation of state-owned enterprises, infrastructure and trade liberalisation. We then turn to investigate the mechanisms using firm and individual-level information. Our firm-level evidence shows that FDI firms not only hire relatively more high-skilled workers but also provide relatively higher wages to high-skilled workers compared to domestic firms. Moreover, the individual-level analysis shows that FDI has a significantly positive spillover effect on wages received by skilled workers employed by state-owned enterprises, but not wages of unskilled workers.     

供需结构优化、分配结构演化与2035年共同富裕目标展望

共同富裕是社会主义的本质要求,中国推动经济社会发展,归根结底是要实现全体人民共同富裕。新发展阶段下中国既要优化供需结构以加快构建新发展格局,又要改善分配结构以全面贯彻新发展理念,而供需结构优化与分配结构演化又是紧密关联的。本文建立了一个包含供给结构、需求结构和分配结构的多部门动态一般均衡模型,将分配结构演化分解到供给结构与需求结构转型上,提出了需求结构通过影响供给结构进而影响分配结构的理论机制。本文对近三十年全球四十余个经济体劳动收入份额和技能溢价的演化进行了发展核算,展示了中国分配结构演化的特征事实、供需动因与国际比较。研究发现,中国分配结构演化道路具有一定的特殊性:一方面,劳动收入份额转为上升,供给侧(需求侧)最主要的推动力是持续提高的劳动密集型产业(消费品)的劳动密集程度;另一方面,技能溢价不断扩大,供给侧(需求侧)最主要的推动力是持续提高的产业内部(消费品)的技能密集程度;供需结构转型在其中也发挥了重要作用。本文还基于历史趋势定量预测了未来中国分配结构的演化趋势,为实现2035年共同富裕目标提供了现实依据与政策参考。     

专业市场核心竞争力的理论分析

核心竞争力是企业逐渐积累起来的,支撑其持续发展的知识和技能的有机结合。就专业市场而言,其核心竞争力的本质是由专业市场本身内在的一般规律所导致的多个能保持和降低交易成本的知识和技能的完备结合。它由核心产品经营技能、组织协调技能和现代信息技术、组织关键能力三个要素构成。基于这一分析,可以得出识别专业市场核心竞争力的基本思路。     

高职会计电算化专业的职业技能培养、训练与测评

按高职会计电算化专业技能的特点和性质要求,培养和发展学生的就业与工作能力,只传授专业理论知识是远远不够的,必须把专业基本知识的教学和基本技能的训练结合起来。技能训练可采用课堂讲授法、课后作业法、摸拟训练法、课外辅导法和社会实践法等技能训练方法。并设计采用相对简化的测评方法对学生学习各项技能的正确性和熟练程度进行测评。     

Hong Kong parents' perceptions of the transference of food preparation skills

Food preparation skills among young adults are associated with healthy food choices, better diets and a greater likelihood of an independent, healthy adult life. This study conducted in Hong Kong aimed to investigate parents' perceptions of cooking skills; to explore the transference of cooking skills in the home setting; to identify parents' expectations regarding the transference of cooking skills; and to inform the development of educational initiatives for developing healthy eating habits. A questionnaire survey was conducted to collect information of the subjects' cooking experience, attitudes about cooking skills, cooking habits at home, family meal habits, transference of cooking culture in the family and the factors influencing the choice of ingredients and cooking. It was administered to 1009 Hong Kong parents (of students aged between 11 and 18, studying in 15 secondary schools). The collected data were analysed using the Statistical Package for the Social Sciences (version 12.0, SPSS, Inc., Chicago, IL, USA) and cross‐tabulation analyses were used to compare the responses of the parents by gender, employment status and income. The results show that parents valued cooking as important life skills for both boys and girls. Parents generally perceived their cooking skills either good (41.9%) or mediocre (54.5%), yet children are rarely taught these skills in the home. Family meals prepared primarily with fresh ingredients are still an important part of the daily routine, and mothers are dominating the roles in food choice decision, cooking and buying the ingredients for family meals. Mothers and schools are expected to be the major channel to teach children cooking skills. Findings suggest that parents are well‐disposed towards providing food and nutrition education at home, but need more support (50% reported that home should be a primary support for learning cooking skills; 36% indicated that the school should have a responsibility to teach children to cook starting in elementary school). Schools may do well to collaborate with families in food literacy education initiatives. Developing individuals' cooking skills paves the way for long‐term health benefits and the well‐being of the local population.     

Bringing Political Skill into Social Networks: Findings from a Field Study of Entrepreneurs

The authors integrate the entrepreneurship literature's sociological and behavioural perspectives and examine the processes through which entrepreneurs first build social networks and then use the network resources for enhancing venture performance. Field interviews of entrepreneurs during a six‐month period reveal that political skill is an important individual‐level factor that influences the construction and use of social networks. Theoretical and practical implications of the major findings are discussed.     

Process innovation capability and subsequent collaborative team performance in travel planning: a knowledge exchange platform perspective

Purpose: Backpacker tourism is flourishing in this century as the high development of Internet technology which enables travellers to search for resources they need easier. The research goal of this study was to exam how virtual skill and collective efficacy affect process innovation capability and subsequent team performance of collaborative design team in a virtual community. Design/methodology/approach: In this study, we formulated the virtual team model from the perspectives of open innovation paradigm and virtual competence, and we collected virtual community participation samples from the online communities. Invitation emails were delivered to numerous trip plan initiators in two well-known online travel communities for filling survey questionnaires for this study. In total, 3000 invitation messages were mailed, of which 373 were returned completed. The model and hypotheses were tested by structural equation modelling. Findings: Virtual competence, including collective efficacy and virtual media skill, is the essential key to facilitate process innovation capability and subsequent team performance success. Besides, knowledge sharing significantly moderates the relationship between process innovation capability and the team performance. Originality/value: Backpackers in the online travel communities have to have not only the willingness to collaborate, but also the abilities of using the correct tool to help with their tasks. When a self-efficacy gets into collective efficacy, it enables the collaborative team to develop with good virtual competencies. Accordingly, trip plan initiator and participants of a virtual team are as expertise contributors between conformity in online communities and online compulsive control tendencies.
