看起來有幾許悖謬與幽默，但卻是事實(shí)。經(jīng)濟(jì)學(xué)中有個(gè)名詞稱為「路徑依賴」，它是類似於物理學(xué)中的"慣性"，一旦選擇進(jìn)入某一路徑（無論是「好」的、還是的），就可能對(duì)這種路徑產(chǎn)生依賴。以下美國鐵軌的故事也許有助于我們理解這一概念，并且加深對(duì)其后果的印象。美國鐵路兩條鐵軌之間的標(biāo)準(zhǔn)距離是四點(diǎn)八五英尺。這是一個(gè)很奇怪的標(biāo)準(zhǔn)，究竟從何而來的？原來這是英國的鐵路標(biāo)準(zhǔn)，因?yàn)槊绹蔫F路**早是由英國人設(shè)計(jì)建造的。為什么英國人用這個(gè)標(biāo)準(zhǔn)呢？原來英國的鐵路是由建電車軌道的人設(shè)計(jì)的，而這個(gè)四點(diǎn)八五英尺正是電車所用的標(biāo)準(zhǔn)。電車軌標(biāo)準(zhǔn)又是從哪里來的呢？原來**先造電車的人以前是造馬車的。而他們是用馬車的輪寬做標(biāo)準(zhǔn)。好了，那么，馬車為什么要用這個(gè)一定的輪距離標(biāo)準(zhǔn)呢？因?yàn)槿绻菚r(shí)候的馬車用任何其他輪距的話，馬車的輪子很快會(huì)在英國的老路上撞壞的。為什么？因?yàn)檫@些路上的轍跡的寬度為四點(diǎn)八五英尺。這些轍跡又是從何而來呢？答案是古羅馬人定的，烏魯木齊的重軌廠，四點(diǎn)八五英尺正是羅馬戰(zhàn)車的寬度，烏魯木齊的重軌廠。如果任何人用不同的輪寬在這些路上行車的話，他的輪子的壽命都不會(huì)長，烏魯木齊的重軌廠。我們再問：羅馬人為什么用四點(diǎn)八五英尺為戰(zhàn)車的輪距寬度呢？原因很簡單。克州的重軌多少錢。。烏魯木齊的重軌廠</p><div
