Introduction of this Edition This edition of NTU Management Review contains five articles. The following is a brief introduction to all of them. For the two articles in the field of marketing management, one article by Huang and Shih investigates the issue related to whether the relationship between enterprises and customers is likely to change over time. This article adopts the concepts of gratitude velocity and trust velocity, and uses longitudinal data gathered from online customers to examine how these constructs influence customers’ attitudinal and behavioral loyalty. They find gratitude velocity and trust velocity have significant positive effects on both forms of customer loyalty respectively. Their study also reveals that relationship benefits have positive impacts on velocity that strengthens the literature regarding relationship marketing in e-commerce.

The query effects are mediated by purchase uncertainty. The article in the field of strategy/technology management by Liang and Liu investigates how the innovation activities of the biotech and new pharmaceuticals industry change after the exogenous shock of the enactment of the Biopharmaceutical Act. The authors adopt Propensity Score Matching (PSM) and Difference-in-difference (DID) approaches to mitigate sample selection bias and endogeneity problems. They find that approved biopharmaceutical firms engage in more innovation investment after the passage of the Biopharmaceutical Act than unapproved firms. They also confirm the policy effectiveness of the Biopharmaceutical Act, finding that approved biopharmaceutical firms are more encouraged to engage in innovation activities than high-tech firms after the Biopharmaceutical Act. In addition, the stimulation effect on innovation exists only for pharmaceutical and low R&D intensity firms. In the subsample analysis of the inter-
