Supply Chain Innovation Research Considering R&D Uncertainty

Innovation is the main competitiveness of enterprises.In recent years,with the increase in R&D costs and R&D complexity of the increase in product life cycle and the growing globalization of competition,enterprises in order to complete all the internal innovation activities within the border has become increasingly difficult.Combined with the enterprise,enterprises in the development of technology,the need to use internal and external knowledge to produce innovative ideas,the use of external and internal market channels for innovative activities,the use of external and internal resources to create greater value for the enterprise.Among them,supply chain innovation has become one of the important ways of open innovation.This study investigates the problem of new product development with technology uncertainty in a supply chain comprising two competing suppliers and a single manufacturer.In this supply chain,the manufacturer playing the role of Stackelberg leader determines the design quality of the product.The two suppliers are in charge of developing the product the manufacturer need and determine the conformance quality to design specication.Using the principal-agent model and taking R&D uncertainty into account,we propose an analytical framework that investigates the effect of upstream competition in new product development.Rich managerial insights into supply chain innovation are provided by analyzing the equilibrium behaviors of decision variables(design quality,the suppliers conformance quality)with respect to three aspects:market and market share,customer preference and cost.As a result,it has been found that market environment optimization and cost reduction are conducive to innovation in the supply chain,competition will promote the improvement of the level of consistent quality,but will reduce the profits of manufacturers,manufacturers should measure their own needs,and rationally allocate the market to achieve the best Effect.When the uncertainty of R&D is large,competition should not be introduced.The achievements of the above research not only enrich and expand the relevant theoretical contents of supply chain innovation,but also promote the application of relevant theoretical models in practice and provide some theoretical basis and support for decision-makers in the actual decision-making process.
