Research Objectives: This paper measures the growth drag and its features under the constraints of energy and environment in poverty-stricken areas.Research Methods:Based on Romer's endogenous growth theory by relaxing the assumption of constant return to scale, a drag-effect model with energy and CO2 emissions and a spatial panel model with spatiotemporal effects are constructed in poverty-stricken areas.Using the panel data of 21 provinces in China from 2000 to 2017, the “tail effect” of economic growth and its factors are examined.Research Results:(1) For a single province, the constraint effect of energy and CO2 emissions on economic growth is widespread in 21 provinces during the sample period with certain distribution features.The total drag value of Jiangxi Province is less than 1%, which is a lower-constraint type.The total drag value of Guizhou, Jilin, Yunnan, Hubei, Gansu, Hunan, Sichuan, Henan, Inner Mongolia, Hebei, Guangxi is greater than 1% and less than 5%, belonging to the higher constraint type.While for Shanxi, Heilongjiang, Ningxia, Anhui, Shaanxi, Chongqing, Qinghai, Hainan and Xinjiang, the total drag value is more than 5% with the strong constraint type.The average of the total drag value of 21 provinces is 5.66%, which shows the strong constraint type.It can be seen that the economic growth pattern of most provinces is still extensive.(2) On the whole, the total drag value during the sample period demonstrates a significant decline, and the total values with ordinary panel and spatial panel are 1.23% and 1.18% respectively.The total drag value in these areas is mainly composed of energy tail effect.The two energy tail effect values are about 2% by the two methods, while the two drag values of carbon emission are - 0.8% approximately.This indicates the economic growth of these areas s is more vulnerable to energy constraints while less environmental constraints.The total drag value measured by the spatial Dubin model is 0.05% lower than that measured by the ordinary panel, which implies that the spatial flow and optimal allocation of production factors have spillover effects on the adjacent areas, which is conducive to reducing the drag value.Research Innovations: This paper designs a spatial analysis on the constraint effect, composition and features of energy and environment of economic growth in poverty-stricken areas.Research Value:This study shows some enlightenment and reference value for poverty-stricken areas how to break through the constraints of energy and environment and take the road of high-quality development. |
