把握主导产业空间格局的演变规律和发展趋势可为缩小区域差距和构建新发展格局提供支撑。前三次科技革命时期,高度依赖国内外资源和国外市场的主导产业受到地理条件、自然资源和国外市场的很大约束,其他主导产业均在市场机制的主导下呈现先聚集后分散的空间演变规律。第四次科技革命时期,京津冀、长三角和粤港澳大湾区将是人工智能产业在未来较长时期的主要聚集区,这一空间格局趋于协调的条件取决于人工智能产业的生命周期、相关基础设施的完善程度以及区域协调发展战略政策的方向和力度等。

《政府工作报告》在向外国介绍中国的政治、经济、外交及军事政策方面发挥着巨大作用，其英译本已成为外界了解中国的一个重要媒介。对于《政府工作报告》的翻译，相关研究分别从目的论、功能对等及其它角度展开并取得一些有益的成果。然而在此领域内，很少有学者对《政府工作报告》中文化负载词的翻译进行系统研究。本文以2003-2012年的《政府工作报告》为语料，利用关联理论系统分析《政府工作报告》中文化负载词的翻译，旨在探讨适用于《政府工作报告》中文化负载词翻译的方法。研究发现，《政府工作报告》中的文化负载词多为生态、社会、语言三类文化负载词。除去少量的汉语成语外，这三类文化负载词多为汉语缩略词。针对不同类型的文化负载词，在关联理论的指导下，译者可采用直译、直译加注释、增译及意译对其进行处理。而且关联理论能够为以上翻译方法提供理论支撑。基于以上分析，本文发现关联理论对译者采用以上翻译方法具有强大的解释力，能够为今后《政府工作报告》中文化负载词的翻译提供方法论的指导。

城镇化是2035年基本实现社会主义现代化的重要引擎,城市群是城镇化的主要空间形态。本文按照“是多少”“主体在哪里”的逻辑顺序,依次研究2035年中国的城镇化率和城市群主体空间形态。在简要回顾城镇化历程的基础上,通过多模型筛选,预测2035年中国的城镇化率将达到73.41%~74.53%,并通过与相关研究比照、与八大发达经济体进行对标研究,对预测结果进行验证。城市群主体空间形态由具有较大首位城市、较强吸引力、紧密经济社会联系、承载未来主导产业和有效促进国家战略格局形成的核心城市群构成,是国家未来国土空间结构的大骨架。为此,从首位城市人口规模、城市人口流动方向、城市群内部经济社会联系、未来主导产业空间分布和国家战略政策影响等五个方面构建分析框架,并依托路径依赖理论预测2035年中国城市群主体空间形态将由京津冀、长三角、粤港澳大湾区、成渝、长江中游五大城市群构成。
