Final answer:
Shenzhen has surpassed Nanjing as Jiangsu province's top economy and foreign trade center, benefiting from its status as a Special Economic Zone and its rapid development into a high-tech industrial city. Option number is correct
Step-by-step explanation:
The city that has replaced Nanjing to become Jiangsu province's number one economy and foreign trade center is Shenzhen. Shenzhen has experienced rapid growth since the early 1980s, transforming from a relatively small city into a major hub of manufacturing, innovation, and international trade. Shenzhen is also noteworthy for being one of China's Special Economic Zones (SEZs), with a focus on attracting foreign investment and boosting economic development. With its own port, proximity to Hong Kong, and partnerships with major corporations like Walmart, Shenzhen has become a magnet for global commerce, far surpassing Nanjing in economic status within the province.
Founded with a population of around 350,000, Shenzhen's population soared to 10.5 million by 2010, reflecting its status as a central player in China's economic expansion. As an SEZ, Shenzhen has benefited from policies designed to encourage foreign investment and economic interaction with global markets. The city's evolution into a high-tech industrial powerhouse has placed it at the forefront of China's charge into the modern, connected world of international trade.
