Yes, Nanjing is very developed.

At present, the development of industrial clusters in Nanjing has initially reached a certain scale, and several industrial clusters with certain influence in the province and even the country have been formed. Among them, the more representative and influential industrial clusters are: Zhujiang Road Electronic Products Street, Changjiang Road Cultural Street, Hunan Road Boutique Street, Confucius Temple Food Street, Daming Road-Ningnan Automobile Street, and Xinjiekou Business District , Jianning Road Wholesale Commercial District, Saihongqiao Building Materials Commercial District, Jiangbei Chemical Park, etc. These industrial clusters gather a large number of similar enterprises and generally have the following characteristics:

First, the types of enterprises are mainly small and medium-sized enterprises. Among the representative industrial clusters, Jiangbei Chemical Industry Park, which is dominated by heavy chemical industry, is a typical industrial cluster of large and medium-sized manufacturing enterprises. Xinjiekou Commercial District is dominated by large and medium-sized commercial and trading enterprises. Other industries Most of the clusters are dominated by small and medium-sized enterprises. These small and medium-sized enterprise-type industrial clusters have absorbed a large number of social labor forces and effectively promoted the development of local economies.

Second, most of them are in the business and trade service industry. In terms of industry classification, Nanjing's industrial clusters are mostly engaged in the production of the tertiary industry, and there are relatively few manufacturing industry clusters. The Chemical Industry Park is a manufacturing cluster focusing on the heavy chemical industry, engaged in the processing of petrochemical products and the development of related industries; although Zhujiang Road Electronics Street is a complex that integrates processing, assembly, research and development and other production and services. It is a comprehensive industrial cluster, but assembly and sales account for a larger proportion; the other industrial clusters are mainly retail, commerce, catering, etc., and fall within the scope of the traditional service industry.

The third is to focus on spontaneous industrial clusters. In terms of the formation of industrial clusters, the Chemical Industry Park is a typical government-led industrial cluster. The formation of Changjiang Road Cultural Street also has strong government planning and guidance factors. The remaining industrial clusters are mainly spontaneous. Among them, the Confucius Temple Food Street, Xinjiekou Commercial District, Jianning Road Wholesale Commercial District and Saihongqiao Building Materials Commercial District were all formed spontaneously based on the continuous expansion of the original tradition; Zhujiang Road Electronic Street, Hunan Road Boutique Street and Daming Road-Ningnan Automobile Street are industrial clusters that have spontaneously formed in the near future in response to the continuous improvement of people's demand level. Of course, there are also factors of government guidance.

Fourth, most of them belong to independent industrial clusters. In terms of the collaborative relationship between enterprises within the industry, there is more collaboration and division of labor between enterprises in the chemical industry park. Now with more and more enterprises settling in, the division of labor and cooperation between enterprises in the park are also getting closer. The closeness makes the industrial chain continue to extend. Therefore, the chemical industry park is a collaborative industrial cluster. Other industrial clusters are mostly independent clusters. Enterprises within the cluster are often in a relatively independent position, lacking collaboration and division of labor. Since these industrial clusters are mostly in the business and trade service industry, the nature of their industries also determines the number of enterprises within the industry. Characteristics of independence and competition between each other.
