New research and development(R&D)institutions are an important part of the national innovation system,playing an important role in promoting the transformation of scientific and technological achievements.In recent years,new R&D institutions have gradually become the driving force of innovation-driven development in China.Taking new R&D institutions in Zhejiang Province as the research object,this paper studies the internal talent training path and performance evaluation mechanism of new R&D institutions in Zhejiang Province by using the literature research method,comparison method,case verification method,and other methods.The investigation results show that there are problems such as lack of material and spiritual support and neglect of the absorption of local talents in the internal talent training,and there are problems such as unclear standards,insufficient data,and opaque processes in the performance evaluation mechanism,which greatly affect the establishment and improvement of the performance evaluation mechanism.Given the above problems,this paper puts forward a forward-looking,oriented,flexible,and compatible talent training path and performance evaluation mechanism,hoping to optimize the effective internal talent training path of new R&D institutions,improve the evaluation performance,and promote healthy development of new R&D institutions in Zhejiang Province. 展开更多

The effect that the market orientation brings to product innovation performance is reported and the degree of product innovativeness is explored. The interdepartmental integration inside the company is also investigated. A series of hypotheses were developed aiming at presenting a conceptual framework to clarify how market orientation contributes to product innovation performance-moderated by the degree of product innovativeness and affected by the interdepartmental integration. Survey data from 36 business units were analyzed based on the respondents in the research. The statistic results suggest a substantial positive effect of market orientation on product innovation performance. Under the condition of incremental innovativeness among the samples, the more innovative the product is, the more improvements in product innovation performance would be achieved. A variety of particular interdepartmental integration mechanisms have been certified to lend more supports to establishing market orientation and improving product innovation performance. 展开更多

This paper identifies low-carbon, energy-efficient, and green economic growth as the primary goals of China's new industrialization and defines productivity under new industrialization which; unlike conventional productivity, simultaneously satisfies these goals. In contrast to conventional methods for measuring productivity, this paper employs a non-radial, non-angular SBM directional distance function to estimate new industrialization productivity of industrial sectors across 30 Chinese provinces, municipalities and autonomous regions between 1998 and 2008. Our research shows that conventional measurements of productivity overestimate industrial growth in China's central and western regions. On the whole, prospects for growth performance of China's industrial sectors are not optimistic. The degree of new industrialization is higher in eastern region than in central and western regions, where balancing industrial growth with resources and the environment is a daunting task. This paper's conclusions support "environmental Kuznets curve" and "Porter hypothesis" but reject "pollution asylum hypothesis ". 展开更多

In this study,we explore the causes and performance outcomes of switching costs in the context of new product development(NPD)from both the supplier and customer perspectives,and discuss the role that switching costs play as moderators and mediators in the relationship between social capital and NPD performance.Based on data from 214 Chinese manufacturers,we employ the structural equation model to test our conceptual model and hypotheses.The results indicate that relationship quality and customer involvement positively and negatively affect switching costs,respectively,and that switching costs negatively affect NPD performance.Switching costs mediate and moderate the relationship between social capital and NPD performance.Furthermore,switching costs significantly and positively moderate the relationship between relationship quality and NPD performance.On the other hand,switching costs insignificantly and negatively moderate the relationship between customer involvement and NPD performance.The theoretical and managerial implications of the findings are discussed. 展开更多

Big data knowledge,such as customer demands and consumer preferences,is among the crucial external knowledge that firms need for new product development in the big data environment.Prior research has focused on the profit of big data knowledge providers rather than the profit and pricing schemes of knowledge recipients.This research addresses this theoretical gap and uses theoretical and numerical analysis to compare the profitability of two pricing schemes commonly used by knowledge recipients:subscription pricing and pay-per-use pricing.We find that:(1)the subscription price of big data knowledge has no effect on the optimal time of knowledge transaction in the same pricing scheme,but the usage ratio of the big data knowledge affects the optimal time of knowledge transaction,and the smaller the usage ratio of big data knowledge the earlier the big data knowledge transaction conducts;(2)big data knowledge with a higher update rate can bring greater profits to the firm both in subscription pricing scheme and pay-per-use pricing scheme;(3)a knowledge recipient will choose the knowledge that can bring a higher market share growth rate regardless of what price scheme it adopts,and firms can choose more efficient knowledge in the pay-per-use pricing scheme by adjusting the usage ratio of knowledge usage according to their economic conditions.The model and findings in this paper can help knowledge recipient firms select optimal pricing method and enhance future new product development performance. 展开更多

Uncertainty is a main source of opportunistic behaviors in research and development cooperations,which challenges strategic decisions ranging from investments to operations.To avoid opportunism arising in cooperations,commitments(either formal contracts or informal communications)are generally made in advance by members of an alliance.However,how does a commitment encourage R&D investments and ultimately enhance the total performance,without loss of flexibility in ex post operations?This study attempts to answer this by investigating a bounded commitment in the context of vertical collaborations in a supply chain.In this exploratory study,a 3-stage game model is used(by backward induction)to examine a two-echelon supply chain under a bounded commitment in NPD.Our analysis shows that upstream R&D investment is stimulated more and that both members are better off under the bounded commitment.At the same time,when the relative bargaining power between the supplier and the manufacturer falls into an appropriate area,it is possible to reach a bounded commitment,and the manufacturer is more sensitive to this relationship.Finally,the bounded commitment restrains opportunistic behaviors,but there is no strong sign that an increase in the ratio of the order outside the chain to the inside one can make firms better. 展开更多

Product innovation practices are documented in the historic 1968and 1982Booze,Allen&Hamilton(BAH)studies followed by the Product Development and Management Association’s(PDMA)four longitudinal best practices/comparative performance assessment studies(CPAS)conducted since the 1990s.These significant NPD best practices benchmarking studies are reviewed within the context of evolution of product innovation practices during 1968-2012.The widening gap in share of profits from new products between the best NPD firms and the rest in 2012informs us that the Schumpeter’s theory of innovation is still relevant in current markets.The PDMA 2012CPAS found that in Asia,small enterprises were not very proficient in NPD.Where as large Asian enterprises needed 7ideas for one commercial success in line with the proficiency of North American enterprises,small Asian enterprises needed 18ideas for one commercial success.A key insight for small Asian enterprises from 2012PDMA CPAS is that it is more important to strive to become the"best"than endeavoring to introduce a large number of new products each year.Insights to improve NPD performance in SMEs are offered along with a systematic framework to achieve successful product innovation.SMEs can begin their improvement effort with self-assessment utilizing the three organizing principles for NPD and eight action categories outlined in the Thota framework for innovation. 展开更多
