在某些时候,想做的和能做的之间总是存有差异,就像这次我们所做的“数字城市”选题。按照最初的设想,我们怀着“初生牛犊不怕虎”的劲头,想要在笔下展现当前城市信息化建设的全貌,但是伴随对“数字城市”了解的深入,我们忽然发现,以目前几个人之力,根本无法达到最初设想的目标,这当中原因很多。首先,“数字城市”概念本身就非常模糊,小到街边的一个信息厅、某个小区安装的智能门禁,大到数字电视工程、城域网,统统可以划到这个概念当中;其次,目前各地建设的水平和层次差距较大,很难用一个标准或尺度来统一评定;另外,目前“数字城市”建设还面临着一些困难和问题,比如国家规划和地方规划之间的协调问题,各类标准之间的统一问题,信息无法共享的问题;而最重要的,是对于大多数城市来说,“数字城市”还只是一种姿态、一种理想,因为它包含的内容太广泛、需要投入的资金太多,它或许要建设几年、十几年、几十年,远非一朝一夕能够实现。因为这样那样的原因,我们不敢自诩为专家,对“数字城市”建设指手画脚,我们只能请来一线建设者和进行理论研究的教授,让他们发表观感;因为这样那样的原因,我们无法记录每个城市信息化建设的全貌,只好选择北京、广州、上海、宁波、深圳这五个“走在前边”的城市,让我们的读者对城市信息化拥有一个直观认识。但无论如何,我们对城市信息化发展的关注不会减少,我们的《省市行》栏目将每月一次走向各地,一切变化,都不会逃脱我们的眼睛。 At some point, there is always a difference between what you want to do and what you can do, just as we did with the “Digital City” topic. According to the original idea, with the momentum of “newborn calves are not afraid of the tiger,” we want to present the full picture of the current urban informatization construction. However, with the deepening understanding of “digital city”, we suddenly realized that with the present few people There are many reasons for this. First of all, the concept of “digital city” itself is very vague. An information hall down to the street, an intelligent access control installed in a residential area, a large digital television project, and a metropolitan area network can all be assigned to this concept. Secondly, In addition, the current “digital city” construction still faces some difficulties and problems, such as the coordination between national planning and local planning, and each Most importantly, for most cities, “digital city” is just a gesture, an ideal, because it contains too much content and needs Too much money invested, it may need to build a few years, ten years, several decades, far from an overnight realization. Because of such a reason, we are not self-proclaimed experts who are desperate for the construction of “digital city.” We can only invite first-line builders and professors who conduct theoretical research to express their feelings. For such a reason, we can not record The overall picture of each city's information construction, had to choose Beijing, Guangzhou, Shanghai, Ningbo, Shenzhen, these five “walking in the front” of the city, so that our readers have an intuitive understanding of urban information. However, our concern for the development of urban informatization will not diminish. Our column of “provincial and municipal cities” will go every month once a month and all changes will not escape our eyes.
