공원녹지 조성이 가구의 전기 및 가스에너지 소비에 미치는 영향 : 부산시민공원 사례를 중심으로

초록

This study aims to analyze the impacts of urban park development on the energy consumption of adjacent households. We employ a difference-in-differences method to scrutinize these dynamics near the Busan Citizen Park that provides a reliable setting for observing the effects before and after the establishment of the park, given its previous use as a U.S. military site. The temporal scope of the study spans from 2011 to 2017, encompassing three years before and after the park’s opening in 2014. With the chosen temporal and spatial settings, we construct monthly panel data on electricity and gas energy consumption for residential complexes, along with relevant independent variables. To address the heteroscedasticity and autocorrelation inherent in the panel data, we specifically utilize a Feasible Generalized Least Squares approach in our difference-in-differences estimation. The empirical results revealed that the urban park led to a reduction of 8.8% and 47% in electricity and gas energy consumption, respectively, in the neighboring residential complexes within its sphere of influence. We postulate that this decrease in energy consumption can be attributed to the ability of the park to lower ambient temperatures, increase humidity, and promote air circulation. These findings suggest that urban parks can play a significant role in achieving carbon neutrality and promoting sustainable urban development.
