An Analysis of the Factors Affecting the Decline of GDP Growth in Tianjin - from the Perspective of Industrial Structure

摘要

Under the background of supply-side structural reform, the national GDP growth rate slowed down, while Tianjin's GDP growth rate declined first. From the perspective of industrial structure, it is of great significance to analyze the influencing factors of the decline of GDP growth rate in Tianjin. This paper chooses the economic data of Tianjin from 2000 to 2018 to analyze the current situation of Tianjin's economic development and the second industrial structure. Based on the data of Tianjin's GDP real growth index, output value structure and employment structure from 1985 to 2018, the VEC model is established to study the impact of Tianjin's second industrial structure on economic growth. Research. It is found that the coordination of industrial structure directly affects total factor productivity, and then affects economic growth. Heavy industries with excess capacity and high energy consumption account for a large proportion in Tianjin's secondary industry. The industrial structure of Tianjin has a long-term and stable impact on economic growth. The increase of the proportion of the output value of the secondary industry promotes economic growth, while the increase of employment plays a restraining role. Accordingly, relevant policy recommendations are put forward.
