Risk-taking is a key factor in corporate competitive advantage, and economic development. The type of strategic configuration that can drive high-level risk-taking is a problem worthy of attention. This study takes 2,219 listed firms in China as samples and performs a fuzzy set qualitative comparative analysis (fsQCA) to explore the linkage effect and path choice of strategic change, corporate social responsibility, innovation, diversification, and financialization with corporate risk-taking (CRT). It finds that: (a) a single strategy does not constitute a necessary condition for high-level CRT; (b) three types of adaptive schemes exist for high-level CRT, among which the risk-taking level is the highest under the path of "Innovation, diversification, and financialization"; and (c) the driving paths of CRT in different regions, industries, and ownership show obvious differences.

Purpose: To explore and analyze the curative effects of micro - implant anchorages in orthodontics. Methods: A retrospective analysis of 65 patients undergoing orthodontic treatment in Department of Stomatology, Binzhou Medical University Hospital, Shandong, China was carried out. Thirty four cases in the treatment group were treated with a micro-implant as the anchorage, while 31 cases of the control group were treated with a palatal bar and facebow as the anchorage, and the curative results of the two groups were then compared. Results: After a 13-month treatment, both anchorages were clinically effective, but the micro-implant anchorage showed higher efficacy. Measurement indices for the test group, including sella-nasion - A point (SNA) angle (- 1.88 ± 0.71), sella-nasion-B point (SNB) angle (1.39 ± 0.42), A point - nasion - B point (ANB) angle (- 2.40 ± 0.83), upper central incisor - lower central incisor (U1 - L1) angle (25.79 ± 5.90), upper central incisor - sella - nasion (U1 - SN) angle (- 10.13 ± 3.68), lower central incisor - mandibular plane (L1 - MP) angle (- 4.22 ± 0.45), upper central incisor - nasion - A point (U1 - NA) angle (- 1.32 ± 1.35) and lower central incisor - nasion - B point (L1 - NB) angle (- 1.32 ± 1.35) of the test group were significantly different those of the control group Overbite (OB), overjet (OJ), intercanine width and the width of the first molars of treatment and control groups were also remarkably). Moreover, micro-implant was observed to be more stable during treatment. Conclusion: Compared with traditional anchorages, micro-implants possess the advantages of slighter trauma, simpler operation, more reliable curative effect and high stability.
