Process implications of the use of the Internet in new product development: a conceptual analysis

New product development requires a long and detailed process with numerous activities such as product line planning, strategy development, concept generation and screening, business analysis, development, testing and validation, manufacturing development and commercialization. Furthermore, each of these activities has its own unique requirements, some requiring information collection from the market, whereas others requiring the collaboration of different people who are involved in the new product development activities. This paper investigates the Internet's role in these activities and develops research propositions. In addition, it discusses how the impact of the Internet might change based on different products and different organizational conditions.     

转型期我国财政支出结构与经济增长关系研究

通过数理方法对我国转型时期的财政支出结构及其与经济增长的关系进行分析研究,发现当前我国财政支出结构不尽合理,必须进一步优化.要严格控制财政直接用于一般竞争性领域,逐步加大对农业、就业和社保、环境和生态、公共卫生、教育和科技等经济社会发展薄弱环节的投入力度.同时要结合财政体制改革和其他配套改革,以提高财政支出效益.     

基于个税递延政策的企业年金保障水平研究

国家明确以税收优惠的形式鼓励和引导企业和个人参加企业年金计划,并于2014年实施了个税递延政策。基于指标模型构建和数据模拟,本文对我国企业年金在个税递延政策实施前后的保障水平进行了比较,通过参数敏感性分析考察了投资收益、工资增长、退休年龄和缴费比例等因素的影响。研究发现,实施个税递延政策后企业职工的养老保障水平在较大程度上低于政策实施前,但不同性别、不同收入水平和不同缴费比例的企业职工保障水平降低的程度有所差异。收入水平和缴费比例越高的男性职工,个税递延政策实施后保障水平降低的幅度越高,但对女性职工而言,这种影响要弱一些。进一步,可以通过增加投资收益、延迟退休年龄和提升缴费比例等方法来提高企业职工的养老保障水平,这与目前正在进行的一系列改革方向也一致。

Local Government,Spatial Spillovers and the Absorption of EU Structural Funds

The allocation of regional policy funds varies dramatically across regions even when one controls for regional development indicators. We investigate the impact of local government performance as well as spillovers in knowledge, financial means and social relations as determinants of regional fund absorption. Government performance is derived within a Data Envelopment Analysis approach. Spillovers are investigated using a spatial Durbin model. Results show that government performance has a positive impact on fund absorption. Spillovers occur in knowledge as well as in financial means. The empirical analyses focus on Special Accession Program for Agriculture and Rural Development in Slovakia using panel data.     

Estimating the impact of farmer field schools in sub‐Saharan Africa: the case of cocoa

This study measures the economic impact of the first phase of the Cocoa Livelihood Program (CLP‐I), a current World Cocoa Foundation (WCF) project, sponsored by the Bill and Melinda Gates Foundation and aimed at improving the livelihood of over 200,000 small cocoa producers in sub‐Saharan Africa via training, crop diversification, and farmer‐based organizations. Using data collected from 2,048 pre‐ and post‐CLP‐I interviews of cocoa producers in Ghana, Cote d'Ivoire, Nigeria, and Cameroon, the results show that yield enhancements attributable to CLP‐I are 32%, 34%, 50%, and 62% in Ghana, Côte d'Ivoire, Nigeria, and Cameroon, respectively. Using a total program cost of $151–$200 per beneficiary and estimated annual benefits of $109–$322 per beneficiary over 25 years, the benefit‐cost ratios are estimated to range from $18 to $62 for every dollar spent on human capital development. These results suggest the WCF should endeavor to increase the number of farmers who receive all, not some, of the components of the program. This would not only help ensure that each producer obtains as much human capital as possible from each of the training programs but increases the probability of reaching the CLP goal of doubling the income of cocoa‐growing households.     

A Proposed Sustainable Rural Development Index (SRDI): Lessons from Hajij village,Iran

While there are many indices to gauge growth and development, there remains an ambiguity on how best to measure the development of tourism in rural locations. Current thinking emphasizes the specific characteristics of a given location and the European Charter for Sustainable Tourism in Protected Areas depicts a requirement for participatory processes in local development. This study is inspired by implementation of the European Charter in Northern Italy, using it as a guideline. The context for this study is Hajij Village in Iran, and the approach adopted differed from that undertaken in Italy with regards to the main target, time and procedures of implementation. The study proposes the novel index based on the weighted averages of 20 variables as used with a sample of 87 members of the Hajij Community. The study explores the possibility of quantitative measurements between the weaknesses, strengths, threats, and opportunities associated with development plans.     

基于教师专业发展的教师团队关键绩效指标体系研究

大学教师的专业发展影响学校的核心竞争力，也影响着培养学生的整体素质。目前比较有效的专业发展是大学教师的专业团队建设。如果能把团队建设和教师专业发展有效结合，不但会促进青年教师的快速成长，也会对学校的未来规划发展起到至关重要的作用。随着团队建设如火如荼的开展，对建设的成果考核是不容忽视的课题，需要考虑在考核时纳入专业发展的绩效考核体系。文章以关键绩效指标为依据，考虑从未来教师专业发展视角来分析团队建设的优势和不足，为后续政策制定、建设规划提供支持。研究结果设计了能够促进教师专业发展的对团队评估的关键绩效考核指标。     

Sustainable entrepreneurship and the Sustainable Development Goals: Community-led initiatives,the social solidarity economy and commons ecologies

The social solidarity economy is an approach to the production and consumption of goods, services and knowledge that promises to address contemporary economic, social and environmental crises more effectively than business as usual. The paper employs the concept of commons ecologies to examine the practices, relationships and interactions among actors and organisations in the social solidarity economy, as well as between them and the mainstream economy, which shape the field and its degree of autonomy in relation to capitalism, through a process defined as boundary commoning. Such process shapes both local and regional commons ecologies, as well as the participation of local and regional actors in wider networks at national, international and global levels. The paper takes a case study-based approach to identify practices, relationships and interactions of commons ecologies in relation to selected community-led initiatives in the UK, Portugal, Brazil and Senegal. Each case study illuminates different qualities of local/regional commons ecologies and their forms of engagement with wider networks. Further, the paper shows that these cases demonstrate how the social solidarity economy may facilitate delivery of the Sustainable Development Goals in a distinctive way. In each case, SSE acts as a vehicle for expressing participants' values and principles consistent with those underlying the SDGs. Local implementation of SDGs is thus an in-built feature of these commons ecologies. The participation of community-led initiatives in international and global networks offers opportunities to learn from local level experiences and successes, potentially strengthening SDG implementation more generally.     

金融发展、企业创新与经济增长

本文通过在一般均衡模型中引入银行部门,考察了金融发展对企业创新和经济增长的影响。基于模型的理论分析表明,在均衡状态下,金融发展可以提高经济中储蓄向投资转化的效率、缓解信息不对称,有效降低了研发部门的外部融资成本,从而促进企业增加研发投入,并推动经济实现更高速的增长。在此基础上,本文以中国31个省份2008—2016年的面板数据对上述结论进行了实证检验,相关结果表明:(1)金融发展对企业研发投入具有显著的促进效应;(2)在工业化程度、外商投资水平较高的地区以及政府支出水平较低、人才资源相对短缺的地区,金融发展的促进作用更加明显;(3)企业研发创新可以有效推动经济增长,且在金融支持实体经济中发挥了重要的中介作用。本文的理论和实证分析揭示了“金融发展—企业创新—经济增长”的内生性传导机理及其在中国的体现,从而为金融支持创新型经济增长的改革逻辑奠定了初步的理论和经验基础。
