Entrepreneurial resource combination is widely recognized as a key enabling factor to a new venture＇s survival and growth, but how and why resources are integrated remain elusive. Borrowing from the theory of resource combination proposed by Sirmon, Hitt and Ireland （2007）, this study empirically examines how environmental uncertainty impacts entrepreneurial resource combination. We also examine the mediating effect of effectual flexibility on the relationship between environmental uncertainty and entrepreneurial resource combination to see how new ventures utilize flexibility to neutralize the threat of environmental uncertainty. The moderating effect of entrepreneurial self-efficacy is also examined to see how entrepreneurs＇ self-cognition affects these relationships. Examining data from 287 new ventures, we find that both environmental dynamism and environmental hostility have significantly positive influence on entrepreneurial resource combination （including entrepreneurial resource cohesion and entrepreneurial resource coupling）. We also find that flexibility mediates the relationship between environmental uncertainty （including environmental dynamism and environmental hostility） and entrepreneurial resource combination. Empirical studies also show that entrepreneurial self-efficacy positively moderates the relationship between environmental dynamism and flexibility but negatively moderates the relationship between environmental hostility and flexibility. Theoretical and practical implications are discussed.

Two-dimensional(2D) CrI_(3) is a ferromagnetic semiconductor with potential for applications in spintronics. However,its low Curie temperature(T_(c)) hinders realistic applications of CrI3. Based on first-principles calculations, 5d transition metal(TM) atom doping of CrI_(3)(TM@CrI_(3)) is a universally effective way to increase T_(c), which stems from the increased magnetic moment induced by doping with TM atoms. T_(c) of W@CrI_(3) reaches 254 K, nearly six times higher than that of the host CrI_(3). When the doping concentration of W atoms is increased to above 5.9%, W@CrI_(3) shows room-temperature ferromagnetism. Intriguingly, the large magnetic anisotropy energy of W@CrI_(3) can stabilize the long-range ferromagnetic order. Moreover, TM@CrI_(3) has a strong ferromagnetic stability. All TM@CrI_(3) change from a semiconductor to a halfmetal, except doping with Au atom. These results provide information relevant to potential applications of CrI_(3) monolayers in spintronics.

资源整合依然是创业领域的热门话题之一,然而现有研究一方面缺乏中国情境下的相关研究,另一方面缺乏对资源整合影响因素的探究。本研究针对中国创业活动实践探究了投机导向对资源整合的内在影响,并基于企业生命周期理论深入探究新企业创建期和成长期投机导向与资源整合的内在关系。研究结果一方面表明新企业开展创业活动的本质即为追求市场机会,因而,无论新企业在创建期还是成长期其基本创业活动均为整合资源以追求获利机会。研究结论另一方面表明技术投机导向仅对新企业获得短期利益有帮助,而对新企业长期发展不利。本研究的结论对于发展和丰富中国情境下创业研究具有重要意义。
