材料一   18世纪中期到19世纪中期，机器的发明引起了欧洲工业生产的革命，使世界从此掀开了新的一页。一位英国经济学家说：我们已经位居世界经济中心。大洋洲有我们的牧羊场，北美西部草原上有我们的牛群，……，而且我们的工业品已遍布势力到达的每一个地方……。
（1）材料一中“19世纪中期，英国位居世界经济中心”主要条件是什么？“工业生产的革命”把人类带入什么时代？
材料二 如右图：

（2）根据图片信息和所学知识，指出当今世界经济呈现怎样的趋势？促使这一趋势加速发展的动力是什么？
（3）面对当今世界经济的发展趋势，你认为中国该如何应对？

材料一：

    进入二十一世纪以来，我国城镇化发展进入加速阶段，社会经济中的城市群体化现象越来越显著，城市群的作用也越来越大。中国传统的省域经济，正在向城市群经济转变。城市群是中国未来经济发展格局中最具潜力的核心地区。

    区域经济发展的质量是由区域内各城市、各要素的融合程度决定的。融合是指在高水平上的城市协调关系和要素合理配置，是通过集聚和扩散实现的。世界三大著名的大湾区城市群，起步于得天独厚的区位条件，港口、公路和机场等基础设施优先发展；同时，产业、资本和市场集聚。

    通过对长三角、粤港澳、京津冀、长江中游、成渝、海西、山东半岛七个城市群的人口、土地、经济概况进行分析，可以发现：近五年人口净流入最多的城市群为长三角城市群，人口吸引力比较高，尤其是“211”、“985”名校聚集的上海、杭州、南京等城市名列前茅；人口涌入最少的则是海西城市群，即使核心城市福州和厦门，城市竞争力也稍弱。从土地占比和地区生产总值占比来看，粤港澳的地均产出最高，是第二名长三角城市群地均产值的二倍之多；地均产出最低的城市群为成渝城市群，仅占粤港澳城市群的1/7。

材料二：

    京津冀城市群的城镇化水平为62.72%，城镇体系趋于完善中，基础设施较为完善，基本判别其现在处于趋于成熟阶段；长三角城市群城镇化水平为68.47%，城镇密度区域较稳定，同时基础设施水平也是所有城市群中最完善的，属于内涵式增长阶段，基本判别其处于成熟发展阶段；而粤港澳城市群城镇化水平高达84.41%，区域内部相对较为平衡，城市空间组织扩散高于集聚作用，城镇密度也处于相对合理的稳定状态，基本判断其处于成熟发展阶段；长江中游城市群、成渝城市群、海峡西岸城市群、山东半岛城市群由于城镇化率比较低，还处于集聚作用为主、扩散作用为辅的外延式发展阶段，处于快速发育阶段。

材料三：表2：七大城市群空间组织结构

注：城市首位度：城市发展要素在最大城市的集中程度。

经济首位度越高，说明该城市在这个地区的经济实力、地位越高。
