东中部地区的发展差距由来已久。自５０年代到７０年代,国家在内地兴建了一大批大中型工业企业,６０年代末期,又进行了大规模的三线建设,这些举措大大加强了内地包括中部地区的工业化的进程。但是,随着８０年代实行改革开放后,东部地区迅速崛起,与中部地区的差距不断拉大。差距 The development gap in the eastern and central regions has a long history. Since the 1950s and the 1970s, the country has built a large number of large and medium-sized industrial enterprises in the Mainland. In the late 1960s, the construction of a large-scale third-line construction has also taken place. These measures have greatly enhanced the industrialization in the hinterland, including the central region. However, with the rapid rise of the eastern region after the introduction of the reform and opening up in the 1980s, the gap with the central region has been widening. gap
