本文以2010–2021年中国A股上市企业为研究样本,实证检验了银行数字化和企业数字化赋能企业绿色转型的协同效应.研究发现银行数字化和企业数字化均有助于促进企业绿色转型,且银企数字化对促进企业绿色转型具有协同效应,这一结论在考虑内生性问题和一系列稳健性检验之后依然成立.机制检验的结果表明银企数字化赋能企业绿色转型的协同效应源于银企数字化具有“信息协同效应”、“信贷配置协同效应”以及“内部治理协同效应”.基于企业内部特征的检验发现,银企数字化的协同效应针对非国有企业、小规模企业、重污染企业以及高科技企业更为有效.基于企业外部环境的检验发现,银企数字化的协同效应在环境规制更强、银行竞争更激烈的地区以及竞争性行业更为有效.进一步对企业绿色转型的经济社会效应进行检验,发现企业绿色转型有效促进了碳减排,但没有证据表明绿色转型在实现企业碳减排的同时是以牺牲企业的发展为代价.本文研究为发挥好银行数字化与企业数字化的协同作用,以数字化赋能企业绿色转型提供一定的政策启示.

针对我国西北部地区恶劣天气和老化线路影响高寒动车组安全可靠运行的问题,开展实际线路运行时振动测试及分析。根据即墨至乌鲁木齐的车辆运行速度和地形特征,划分青岛—济南、济南—西安、西安—兰州、兰州—乌鲁木齐4个区间,对比分析不同区间内的振动有效值。结合IEC 61373标准,对比分析实测振动有效值、冲击峰值与标准值的差异。通过振动频谱分析牵引变流器不同部件的振动特性,利用统计容差法编制不同部件的实测载荷谱,并利用有限元方法分析中频和高频振动对牵引变流器结构的影响。结果表明,济南—西安区间内的振动高于其他区间,西安—兰州区间内的冲击高于其他区间;柜体吊耳和控制箱的振动主要体现在垂向与纵向,而横向较小,且以中频段和低频段为主;冷却风机的振动集中在低频段,来自于风机转频;功率模块振动以横向和纵向为主,中频段和高频段的振动远大于低频段。

So far, it has been a challenge for existing interatomic potentials to accurately describe a wide range of physical properties and maintain reasonable efficiency. In this work, we develop an interatomic potential for simulating radiation damage in body-centered cubic tungsten by employing deep potential, a neural network-based deep learning model for representing the potential energy surface. The resulting potential predicts a variety of physical properties consistent with first-principles calculations, including phonon spectrum, thermal expansion, generalized stacking fault energies, energetics of free surfaces, point defects, vacancy clusters, and prismatic dislocation loops. Specifically, we investigated the elasticity-related properties of prismatic dislocation loops, i.e., their dipole tensors, relaxation volumes, and elastic interaction energies. This potential is found to predict the maximal elastic interaction energy between two 1/2 loops better than previous potentials, with a relative error of only 7.6%. The predicted threshold displacement energies are in reasonable agreement with experimental results, with an average of 128 eV. The efficiency of the present potential is also comparable to the tabulated gaussian approximation potentials and modified embedded atom method potentials, meanwhile, can be further accelerated by graphical processing units. Extensive benchmark tests indicate that this potential has a relatively good balance between accuracy, transferability, and efficiency.
