經(jīng)濟(jì)學(xué)中有個名詞稱為「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「壞」的），就可能對這種路徑產(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。那么，為什么英國人用這個標(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，四點(diǎn)八五英尺正是羅馬戰(zhàn)車的寬度。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長。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，這是兩匹拉戰(zhàn)車的馬的屁股的寬度。故事到此應(yīng)該完結(jié)了。重慶的重軌多少錢四川的重軌多少錢。</p><div

但是，鐵廠剛開始投產(chǎn)就面臨一個**大的實(shí)際問題——資金不足。清**所撥費(fèi)用已全部用完，而投產(chǎn)所需資金至少100萬兩白銀。張之洞奏請朝廷，提出設(shè)備“分量、分撥”投產(chǎn)，以解決資金周轉(zhuǎn)問題，減少開工費(fèi)。他還建議朝廷將建造湖北***炮廠等工廠的資金“撥借”過來。緊接著。有一個大難題接踵而來，由于缺乏經(jīng)驗(yàn)，前期技術(shù)準(zhǔn)備不充分，所用的原材料大冶鐵礦砂和煉鋼爐不匹配，無法提取大冶鐵礦砂中所含高濃度的磷，造成試軋出的鋼軌質(zhì)脆易裂，不能普遍使用，鐵廠經(jīng)營陷入了困境。1896年，漢陽鐵廠改為官督商辦，張之洞舉薦盛宣懷接手，之后又對冶煉設(shè)備進(jìn)行了重整改造，鋼鐵質(zhì)量轉(zhuǎn)佳，經(jīng)營銷售一度頗有生機(jī)。西洋報(bào)刊曾在1901年評論道：“漢陽鐵廠之崛起于中國，大有振衣千仞、一覽眾山之勢?！敝劣阡撥壍馁|(zhì)量問題，鐵廠一直到1904年才徹底找到病根，軋出了完全合格的鋼軌。至辛亥**前，鐵廠年生產(chǎn)鋼軌約2萬噸，是中國近代鐵路建設(shè)中***的國內(nèi)鋼材供應(yīng)商，它不僅向盧漢鐵路提供鋼軌，而且凡是盛宣懷組織的中國鐵路總公司督辦的鐵路均優(yōu)先購用漢陽鐵廠鋼軌。據(jù)估算，至1922年年底，漢陽鐵廠鋼軌所鋪設(shè)的鐵路占中國已建鐵路里程的1/3。1924年，漢陽鐵廠在經(jīng)過了短暫的黃金期后。新疆鐵路重軌多少錢一噸</p><p
