在肯定成绩的同时，我们也清醒看到面临的困难和挑战。从外部风险看，世界变乱交织、动荡加剧，单边主义、保护主义不断升级，经贸问题泛政治化、泛安全化滋长蔓延，多边主义、自由贸易受到严重冲击，世界经济动能疲弱；霸权主义和强权政治威胁上升，国际经济贸易秩序受到严峻挑战；地缘政治风险持续上升，部分地区冲突延宕外溢；大国博弈更加复杂激烈，我国发展环境的复杂性、严峻性、不确定性上升。从内部困难看，发展不平衡不充分问题仍然突出，一些长期积累的深层次结构性矛盾加快显现。供强需弱矛盾突出，房地产开发投资持续下降，基础设施投资增速由正转负，制造业投资增速进一步放缓，整体投资下行压力加大，消费增长动力不足，价格水平持续低位运行；一些企业生产经营困难增多，部分行业“内卷式”竞争仍然突出，市场预期偏弱；新旧动能转换任务艰巨，传统动能增长放缓，新兴产业对经济的带动作用有待增强；群众就业和增收难度加大，公共服务仍有不少短板弱项，节能降碳减污任务较为艰巨；部分地方财政收支矛盾突出，统筹经济社会发展与化解债务的难度较高，房地产市场仍在调整，重点领域风险隐患较多。

And in 2018, my Ph.D. student Aaron Held and I had a memorable moment. The previous year, we had already found that a fixed point would force the top quark to have close to the measured mass. And we were investigating whether it could also account for the mass of the top quark’s sibling, the bottom quark. They’re supposed to be identical twins in the eyes of gravity, because their distinctive quantum properties are not things that gravity is sensitive to, but experiments have found that they have different masses.。业内人士推荐官网作为进阶阅读
