A Morphology-Driven Method for Measuring Technology Complementarity:Empirical Study Involving Alzheimer’s Disease

Purpose:Measuring the exact technology complementarity between different institutions is necessary to obtain complementary technology resources for R&D cooperation.Design/methodology/approach:This study constructs a morphology-driven method for measuring technology complementarity,taking medical field as an example.First,we calculate semantic similarities between subjects(S and S)and action-objects(AO and AO)based on the Metathesaurus,forming clusters of S and AO based on a semantic similarity matrix.Second,we identify key technology issues and methods based on clusters of S and AO.Third,a technology morphology matrix of several dimensions is constructed using morphology analysis,and the matrix is filled with subjects-action-objects(SAO)structures according to corresponding key technology issues and methods for different institutions.Finally,the technology morphology matrix is used to measure the technology complementarity between different institutions based on SAO.Findings:The improved technology complementarity method based on SAO is more of a supplementary and refined framework for the traditional IPC method.Research limitations:In future studies we will reprocess and identify the SAO structures which were not in the technology morphology matrix,and find other methods to characterize key technical issues and methods.Furthermore,we will add the comparison between proposed method and traditional and mostly used complementarity measurement method based on industry chain and industry code.Practical implications:This study takes medical field as an example.The morphology-driven method for measuring technology complementarity can be migrated and applied for any given field.Originality/value:From the perspective of complementary technology resources,this study develops and tests a more accurate morphology-driven method for technology complementarity measurement.

Government Subsidy’s Effect on the Channel Strategies of Energy-Saving Supply Chain

As subsidy is a popular form of stimulating consumption,not only for home appliances market,the effectiveness of selling promotion subsidies need to be analyzed.In this paper,we check the role of promotion subsidies in the offline channel layout by establishing three models,i.e.,no subsidy,customer rebate and retailer subsidy.Two kinds of online-to-offline strategies are considered,which are retailer’s opening separate and sharing offline stores.It is gotten that:both customer rebate and retailer subsidy increase the possibility of opening offline channels by sharing offline store strategy,but customer rebate takes high price than no subsidy while retailer subsidy is on the contrary.With the growing subsidy,both customer rebate and retailer subsidy could make offline channels opened by separate or sharing offline store strategy,but the customer rebate brings more possibilities.Both customer rebate and retailer subsidy require less social welfare to open offline channel,but the customer rebate brings more consumer surplus of opening offline channels than retailer subsidy for a given market area.Therefore,government should give the subsidy to customer,not to retailer,even if it brings the increasing of product’price.
