How to Measure a Two-Sided Market.

Applying the theories of complex network and entropy measurement to the market, the two-sided market structure is analyzed in constructing the O2O platform transaction on the entropy measurement of the nodes and links. Market structure entropy (MSE) is initially introduced to measure the consistency degree of the individuals and the groups in the O2O market, according to the interaction in the profits, the time/space, and the information relationship. Considering that the market structure entropies are changing upward or downward, MSE is used to judge the consistency degree between the individuals and the groups. Respectively, considering the scale, the cost and the value dimensions, MSE is expanded to explain the market quality entropy, the market time-effect entropy, and the market capacity entropy.MSE provides a methodology in studying the O2O platform transaction and gives the quantitative index in the evaluation of the O2O market state.

Establishment of Evaluation Model of O2O Platform Service Quality Based on SERVQUAL Scale / 中国药房

OBJECTIVE:To establish a pharmacy online to offline (O2O) platform service quality evaluation model,and to provide reference for platform operators to improve the service quality. METHODS:Using SERVQUAL scale,combining the situa-tion of pharmacy O2O platform development in China,the reliability,safety and aspects of O2O platform were analyzed to sum up primary evaluation index of pharmacy O2O platform service quality. Based on this,the expert interviews questionnaire was de-signed. According to the questionnaire results,indicators were modified and empowered to construct the pharmacy O2O platform service quality evaluation model;the reliability and validity of model were validated. RESULTS & CONCLUSIONS:According to the connotations of each dimension analysis in the SERVQUAL scale and expert interview results of pharmacy O2O platform ser-vice quality,pharmacy O2O platform service quality evaluation model is constructed,including five indicators as“reliability”“se-curity”,and 18 secondary indexes as the“number of platform pharmacy”“pharmacy qualification show”“pharmacy type”. The re-sults of model index reliability and validity verification show that model construction is reasonable and can provide reference for platform operators improving service quality. Follow-up research should give full consideration to the Chinese consumer behavior habits,personal preferences and other factors to build more suitable pharmacy O2O platform service quality evaluation model in China.
