Improving new product development using big data: a case study of an electronics company

Big data is becoming more important to the new product development (NPD) efforts of global firms. Although the term of big data is not new, very few studies have investigated how firms can harvest big data to facilitate NPD. The purpose of this article is to present the means by which big data can be used to assist firms in NPD to shorten the time to market, improving customers’ product adoption and reducing costs. This research is based on a two-step approach. First, we identified and analysed three world-leading firms that have successfully integrated big data in supporting their NPD. Then, the observations from the firms were used to determine the principle involved in leveraging big data to reduce product development lead times and costs. Given the exploratory nature of the research objective, a participant-observation case study is adopted in which during a 6-month period a NPD project in a fast moving high-tech industry was investigated. This study provides empirical confirmation for the three principles to big data supported NPD: (a) Autonomy; (b) Connection; and (c) Ecosystem. It is termed the ACE principles which we believe represent a paradigm shift to help firms unlock the power of big data and make NPD faster and less costly. This article provides guideline to firms in harvesting big data to better support their NPD: it allows organisations to launch new products to market as quickly as possible; it helps organisations to determine the weaknesses of the product earlier in the development cycle; it allows functionalities to be added to a product that customers are willing to pay a premium for, while eliminating features they do not want; and it identifies and then prioritises customer needs for specific markets.     

人力资本、职业培训与家政从业人员工资收入——基于上海市调查数据的分析

在二元劳动力市场格局下,次级劳动力市场中从业者的职业发展前景黯淡。本文采用赫克曼样本选择模型,在控制了样本自选择偏误后,发现在次级劳动力市场中人力资本与职业培训对从业者的工资收入具有显著的提升作用。具有较高学历、接受过职业培训、拥有中高级职业资格证书的家政从业人员,其单位工资水平更高。在家政行业内部从事不同家政服务内容者具有显著的工资差异,母婴护理与养老护理具有较高的工资优势。目前,家政从业人员对自身职业有着较高的认同感,在就业中融入了一定的个人发展。在人口老龄化的社会中,要引导家政行业发展,将其纳入老龄事业。

Determinants of the decreasing term structure of relative yield spreads for taxable and tax-exempt bonds

The empirical finding that the relative yield spread for taxable and tax-exempt bonds decreases across the term structure is usually attributed to tax differentials and/or arbitrage opportunities. Using monthly data, it is found that the decresing term structure of relative yield spreads is determined by the decreasing forward marginal tax rate; increasing default risk premium; increasing tax-timing option premium; and expected rate of inflation
