以大城市为中心的市话建设,因其具有市场广泛、效益显著的特点,而成为当前通信发展的战略重点之一。但是,市话投资效益能否得到充分的发挥,关键还在于怎样使邮电产品尽快转化为商品,实现其自身价值,从而加速资金回收,为进一步发展通信建设积累资金。但是,从目前情况看,这一点仍是个薄弱环节。“六五”期间,全国市话增容132万门,而同期新增市话用户84.8万个,为新增设备的64.2%。其中,近四分之一的省,市、区局新增用户只占新增设备数的一半左右。“六五”期间,我省用于增加市话的投资额占全部投资总额的三分之一,而市话收入的增长,只占全部收入增长的五分之一。五年 The construction of local call centering on big cities has become one of the strategic focuses of current communications development because of its broad market and significant benefits. However, the key issue of whether local investment returns can be fully realized is how to transform the postal products into commodities as soon as possible to realize their own value so as to speed up the recovery of funds and accumulate funds for the further development of communications. However, from the current situation, this is still a weak link. During the period of the Sixth Five-Year Plan, the number of local telephone calls in the country was increased by 1.32 million while the number of new local telephone subscribers in the same period was 848,000, accounting for 64.2% of the new equipment. Among them, nearly a quarter of provinces, municipalities and autonomous regions, the new user accounts for only about half the number of new equipment. During the “6th Five-Year Plan” period, the amount of investment in the province for increasing the number of local calls accounted for one third of the total investment, while the local telephone revenue growth accounted for only one-fifth of the total revenue growth.
