????東京市政府已經(jīng)和北京市政府在廢物及廢水處理領(lǐng)域進行技術(shù)交換。東京是世界上規(guī)模最大的城市，建有全球技術(shù)最先進的污水處理和循環(huán)利用系統(tǒng)之一。借助這樣的技術(shù)，東京在聯(lián)合國（United Nations）清潔城市榜上的排名從末尾一躍進入了領(lǐng)先者的行列。

????日本第二大城市大阪也希望為中國提供浮式太陽能水凈化器。這種設(shè)備每天可凈化2,400升水，正用于大阪受到污染的運河系統(tǒng)

????雖然近期日本在環(huán)保方面并不是毫無問題，但日本的技術(shù)專家樂觀地認為，日本的其他綠色技術(shù)能引起中國的興趣，比如最近開發(fā)的智能城市系統(tǒng)。它有助于促進可持續(xù)性規(guī)劃和發(fā)展。就連川崎，這個日本工業(yè)迅猛而無節(jié)制增長所產(chǎn)生的“骯臟老城”如今也在通過每年一次的生態(tài)博覽會向全世界推廣本地開發(fā)的環(huán)保技術(shù)，而且還建有日本最大的太陽能發(fā)電站。

????中國的情況可能不會那么容易發(fā)生改觀。盡管日本的綠色科技產(chǎn)業(yè)可能會得到中國官方的支持，但實際情況可能會證明，中國的國企和地方利益并不像20世紀80年代日本的工業(yè)界那么容易對付。盡管存在成本問題，但是歸功于持續(xù)不斷的社會壓力，經(jīng)過長時間的較量，日本工業(yè)界最終還是接受了20世紀70年代頒布的《大氣污染防治法》所提出的要求。中國存在污染問題，但依然能夠賺到利潤。因此，如何說服中國采用日本昂貴的污染防治新技術(shù)，可能會成為日本面臨的又一項任務(wù)。（財富中文網(wǎng)）

????Tokyo and Beijing city governments already cooperate through a technical exchange in waste and water management. Tokyo, the biggest city in the world, already has one of the most technologically advanced sewage and recycling systems anywhere. Such technology helped pull Tokyo out of the bottom of a United Nations list for clean cities to a place near the top.

????Japan's second city, Osaka, meanwhile wants to offer up its floating, solar-powered water purifiers that can each clean 2,400 liters per day in its sullied canal system.

????Although Japan's recent environmental record is not without blemish, the country's technocrats are bullish that it can interest China in other green technologies such as its recently developed smart cities that help promote sustainable planning and development. Even Kawasaki, the "dirty old town" product of Japan's spectacular, but unregulated industrial growth, now boasts an annual Eco Fair which promotes its homegrown environmental technologies to the world and is now host to Japan's largest solar power plant.

????Changes in China may not come so easily. The Japanese green tech industry may have official China on its side, but state-owned corporations and local vested interests could prove less tractable than industrial Japan of the '80s. After a long fight, Japanese industry eventually buckled under Japan's clean air acts enacted in the '70s, despite the costs, thanks to persistent social pressure. Persuading a dirty but profitable China to take up Japan's expensive new antipollution technologies may prove another task altogether.
