Nowadays, the scale of international trade is expanding at a great pace, leading to the development of the economy of different countries. Global industrialization and urbanization are developing with each passing day, and this fast economic expansion is putting a tremendous impact on the environment. Like the other countries, the scale of Chinese export trade is also increasing with time, resulting in the stable economy of our country. With the improvement of living standards, people are continuously demanding high environmental facilities. Further, the impact of trade (enterprises, companies, industries, etc.) on the ecological environment has become a worldwide problem because economic progress brought forth by trade expansion may directly affect the environment by causing pollution to rise or the degradation of natural resources. This indeed is a serious issue; therefore, various countries have started focusing on the impact of export trade on the ecological environment. In recent years, the issue of economic benefits and the environmental impact of export trade has become a hot topic of research. Therefore, this study focuses on the relationship between trade, economy, and environmental quality in China. For the accomplishment of our research study, we selected Anhui free trade zone (FTZ) as an example to analyze the interaction between the economic benefits of Anhui export trade and the local environment. It is among the top trading provinces in China having a faster economic development. In order to accurately study the economic benefits and environmental impact of export trade in the Anhui FTZ, this paper selects industrial waste gas, wastewater, and solid waste to establish an export trade environmental impact indicating system. After comparative analysis, three factors that include industrial soot (dust) emissions for export trade, chemical oxygen demand for trade, and general industrial solid waste dumping and discards are selected to evaluate the impact on the environment of the free trade zone. Based on this, the export trade environment vector autoregressive (VAR) model is established, and the variance decomposition method is used to analyze the dynamic impact of various factors on the environmental impact index. Further, we established an economic benefit VAR model based on the export economic benefit index (EI), export value (EV), and export product concentration (EPC) index and judged the economic benefit of the Anhui free trade zone based on the contribution rate of the obtained three factors. The experimental results show that the export volume and product concentration directly affect the economic benefits of the region, and at the same time, the expansion of export trade promotes the growth of economic benefits.
