我要說一點很重要但影片沒講到的部分。這項最大的下水道系統是為了刺激當年日本的泡沫後的經濟。在經濟學中,建造基礎建設可以刺激經濟發展,而當時日本政府希望用大量的基礎建設帶動泡沫經濟後慘不忍睹的經濟。 日本在西元1992年3月房價崩潰。而當年日本政府做了許多刺激經濟的公共政策。而建造基礎建設就是日本政府想出的最佳解決方案。因為建造基礎建設需要大量人力大量資源,而推動基礎建設可以讓大量人力和資源在供給市場流通,資金可以可以在市場繼續流轉。再來基礎建設也可以提供都市生活的便利性,提供更好的居住環境。所以日本政府不但蓋了下水道排水系統,也蓋了世界上數一數二複雜的鐵路規畫。 影片提到這項下水道工程30億美元,而鐵路計畫也讓日本政府大量舉債。理論上這樣可以刺激日本泡沫破滅低迷的經濟,但經濟還是沒辦法起來。 I'm going to say something important but not covered in the video. The largest sewer system was built to stimulate Japan's post-bubble economy. In economics, building infrastructure can stimulate economic development. At that time, the Japanese government hoped to build a lot of infrastructure to drive the horrific economy after the bubble economy. Japan's house prices collapsed in March 1992. At that time, the Japanese government made many public policies to stimulate the economy. Building infrastructure is the best solution the Japanese government has come up with. Because the construction of infrastructure requires a lot of manpower and resources, and promoting infrastructure construction can allow a large number of manpower and resources to circulate in the supply market, and funds can continue to circulate in the market. In addition, infrastructure construction can also provide the convenience of urban life and provide a better living environment. Therefore, the Japanese government not only built the sewer drainage system, but also built one of the most complicated railway plans in the world. The film mentions the $3 billion sewer project, and the railroad project has left the Japanese government heavily indebted. In theory, this could stimulate Japan's sluggish economy, but the economy is still unable to recover.
