Decrease in urban energy intensity: Is there a role for urban spatial structure?

Abstract

Using satellite remote sensing data and the threshold panel model, this research explores the impact of urban spatial structure on urban energy intensity. The evaluation index of urban spatial structure includes compactness and elongation rate. Results from empirical studies of 30 cities in China from 1996 to 2016 indicate that urban spatial structure has a significant impact on urban energy intensity. There is a positive correlation between urban spatial structure elongation rate and urban energy intensity. However, with the increase in urban fixed assets investment, there is a negative correlation between elongation rate and energy intensity, which implies an inverted‐U relationship. The results also indicate that urban compactness is negatively correlated with urban energy intensity. Therefore, proper management of urban spatial structure can effectively promote the reduction in urban energy intensity. The elongation of urban suburb space and the compactness with the internal space of the city can be developed simultaneously. While playing the role of a spatial agglomeration economy, the negative effects of over agglomeration are avoided, which jointly promote the reduction in urban energy intensity.

Energy consumption inequality in China: What can an agent-based model tell us?

“…Energy consumption involves multiple heterogeneous agents. 21 Industrial structure, population, and investment in fixed assets can affect energy consumption. 22,23 Meanwhile, regional energy planning and macroeconomic cycles also affect energy consumption.…”

“…74 This is closely related to energy consumption habits and culture. 75 There are also studies showing that urban sprawl in China has led to a "solidification" of energy consumption patterns, 21 which cannot be changed in the short term. Therefore, starting from the consumer side to reduce the Gini coefficient of energy consumption is very ineffective.…”

Quantitative evaluation of China's energy supply policies in the ‘13th Five‐Year Plan’ period (2016–2020): A PMC index modelling approach incorporating text mining

“…Moreover, after preliminary calculations, China's total amount of energy consumption reached 4.98 billion tons of standard coal in 2020, showing a 2.2% increase. The proportion of coal consumption in total energy consumption decreased by 1%, whereas the proportion of clean energy consumption increased by 1.1% 4,5 . It is evident that China's energy supply capacity is being strengthened, and the energy consumption structure has been further optimised.…”
