作为国家经济基石的大中型企业,主要分布在全国各大中城市,构成城市经济的主体。南京作为大中型企业相对集中的城市,其大中型企业的规模、效益等与全国直辖市、计划单列市相比,占有一定地位。比较来看,既有其优势,也有明显差距与不足。 The large and medium-sized enterprises, which are the cornerstones of the national economy, are mainly distributed in large and medium-sized cities throughout the country and constitute the main body of the urban economy. As a relatively concentrated city, large and medium-sized enterprises in Nanjing have a certain status in terms of scale, efficiency, etc. compared with the municipalities directly under the central government and cities with separate plans. In comparison, there are both advantages and obvious gaps and shortcomings.
