urbanization; residential energy consumption; divisia decomposition
我国城镇化进程持续加快,1996年以来年均增长1.4个百分点,同时,居民生活直接能源消费快速增长。区域发展不平衡使各区域城镇化水平与居民生活直接用能存在差异。本文探讨2000—2011年间城镇化进程对各区域居民生活赢接用能的影响规律。根据Divisia指数分解法。将居民生活直接用能变化分解为人口增长效应、城镇亿率增加效应、城镇居民人均生活用能变化效应和农村居民人均生活用能变化效应。饕重分析了东、中、谣部区域城镇化率增加对区域生活直接用能总量变化、各类型能源品种变化的贡献及边际贡献。结果发现:2000—2011年间。城镇化进程对东、中、话部和东北区域居民生活直接甩能的贡献分别为4.2%誓0.6%,4.1%。-0.01%,人口结构的变动对中部居民直接用能的拉动作用明显;窖城镇化率每提高一个百分点,对各区域闻生活直接用能贡献差别不大。其中。对东部区域增量贡献最小;@与其他区域不同。中部区域城镇化进程对煤炭消费有增量贡献;东、中部区域城镇化进程对油品消费增量的贡献是西部区域的3—4.倍;东部区域城镇化进程对电力消费增量的贡献接近0;④城镇化率每增加一个酉分点,对东部地区油品消费增量贡献分别是中西部区域的1.9和2.3倍;对天然气和热力消费增量贡献的情况类似,均是西部区域最高,是东部和中部14—2.6倍。研究结论对城镇化进程下开展区域能源管理、节能减排具有指导意义。
我國城鎮化進程持續加快,1996年以來年均增長1.4箇百分點,同時,居民生活直接能源消費快速增長。區域髮展不平衡使各區域城鎮化水平與居民生活直接用能存在差異。本文探討2000—2011年間城鎮化進程對各區域居民生活贏接用能的影響規律。根據Divisia指數分解法。將居民生活直接用能變化分解為人口增長效應、城鎮億率增加效應、城鎮居民人均生活用能變化效應和農村居民人均生活用能變化效應。饕重分析瞭東、中、謠部區域城鎮化率增加對區域生活直接用能總量變化、各類型能源品種變化的貢獻及邊際貢獻。結果髮現:2000—2011年間。城鎮化進程對東、中、話部和東北區域居民生活直接甩能的貢獻分彆為4.2%誓0.6%,4.1%。-0.01%,人口結構的變動對中部居民直接用能的拉動作用明顯;窖城鎮化率每提高一箇百分點,對各區域聞生活直接用能貢獻差彆不大。其中。對東部區域增量貢獻最小;@與其他區域不同。中部區域城鎮化進程對煤炭消費有增量貢獻;東、中部區域城鎮化進程對油品消費增量的貢獻是西部區域的3—4.倍;東部區域城鎮化進程對電力消費增量的貢獻接近0;④城鎮化率每增加一箇酉分點,對東部地區油品消費增量貢獻分彆是中西部區域的1.9和2.3倍;對天然氣和熱力消費增量貢獻的情況類似,均是西部區域最高,是東部和中部14—2.6倍。研究結論對城鎮化進程下開展區域能源管理、節能減排具有指導意義。

China is experiencing acceleration of urbanization process that with an average annual growth of 1.4% since 1996. Meanwhile residential energy consumption in China is also in a rapid growth in this period. Moreover, given the fact of China' s unbalanced regional development, the evolutions of urbanization and residential energy use, and the relationships between them in different regions may differ from each other. This paper then studies the individual evolutions of urban effects on direct use of residential energy in Chinese four regions during 1996 - 2011. By using Divisia index decomposition method, we decompose the changes of residential energy consumption in four regions into four driving factors, i.e. population growth effect, urbanization effect, effect of urban residential energy consumption per capita and effect of rural residential energy consumption, hnpacts of urbanization rate increase on residential energy consumption in eastern, western, and central regions are focused, of which absolute and marginal contributions on total energy consumption and each type of energy consumption are analyzed. The results show that : ( 1 ) urbanization rate increase contributes to residential energy consumption in eastern, central, western, northeastern regions by 4.2%, 20.6%, 4.1% , and -0.01% respectively. (2) Contribution from urbanization rate increases to residential energy consumption exists little difference among regions, of which that to eastern region is the least. ( 3 ) Unlike other regions, urbanization effect in central region on its coal consumption is positive; urbanization increases in eastern and central regions contribute to their oil consumption by 3 -4 times of that in western region; urbanization effect in eastern region on its electricity eonsumption is close to zero. (4) Every one percentage rise in urbanization rate in eastern region contributes to its residential oil consumption by 1.9 and 2.3 times of that in central and western regions respectively, and the situations to natural gas consumption and heat consumption are similar, both with highest contribution in western region. The conclusions provide some implications for regional energy management and energy conservation and emission reduction.
