新型城鎮(zhèn)化改革與縮小城鄉(xiāng)收入差距

——基于縣級(jí)行政區(qū)面板數(shù)據(jù)的實(shí)證研究

【摘要】城鄉(xiāng)收入差距居高不下是全球性難題,我國(guó)新型城鎮(zhèn)化改革成果能否公平惠及不同人群和地區(qū),進(jìn)而縮小城鄉(xiāng)居民收入差距,是一個(gè)備受關(guān)注的問題。本文借助三批新型城鎮(zhèn)化綜合試點(diǎn)提供的準(zhǔn)自然實(shí)驗(yàn)背景,基于2012年至2019年2805個(gè)縣級(jí)行政區(qū)的面板數(shù)據(jù)和多期雙重差分模型,使用插補(bǔ)估計(jì)方法對(duì)政策效應(yīng)進(jìn)行評(píng)估后發(fā)現(xiàn),在這一較短時(shí)間段內(nèi),新型城鎮(zhèn)化改革對(duì)試點(diǎn)縣級(jí)行政區(qū)的城鄉(xiāng)人均可支配收入差距有正向影響。產(chǎn)業(yè)結(jié)構(gòu)轉(zhuǎn)型升級(jí)加快、地方政府宏觀調(diào)控力度加大、非農(nóng)固定資產(chǎn)投資占比提高、縣域耕地面積減少以及由于戶口性質(zhì)轉(zhuǎn)換導(dǎo)致的純統(tǒng)計(jì)意義上的城鄉(xiāng)收入水平變化,是該影響的重要作用機(jī)制。異質(zhì)性分析顯示,中部和西部試點(diǎn)地區(qū)的城鄉(xiāng)收入差距在政策作用下顯著縮小,東部地區(qū)則相反,這一差異表明新型城鎮(zhèn)化改革向中西部?jī)A斜的政策舉措有利于縮小城鄉(xiāng)差距。

New-type Urbanization Reform and the Urban-rural Income Gap

—An Empirical Research Based on Panel Data from County-level Administrative Regions

Hou Wanwei

Abstract: Amid the global challenges of the persistent income gap between urban and rural areas, a key issue is whether the achievements of China's new-type urbanization reform can equitably benefit different populations and regions and narrow the income gap between urban and rural residents. This paper, leveraging the quasi-natural experiment provided by three batches of new-type urbanization comprehensive pilot programs and using panel data from 2,805 county-level administrative regions from 2012 to 2019 along with a multi-period difference-in-differences model, evaluates the policy effects using the imputation estimation method. The findings indicate that within this relatively short time frame, the new-type urbanization reform widened the urban-rural income gap in the pilot regions. The main mechanisms of this impact include accelerated industrial transformation and upgrading, increased macroeconomic regulation by local governments, a higher proportion of investment in non-agricultural fixed assets, reduced arable land in county areas, and variations in urban and rural income levels by statistics due to the conversion of household registration status. Heterogeneity analysis shows that the urban-rural income gap in the central and western pilot areas has significantly narrowed under the policy impact, while the opposite is true in the eastern counterparts. This difference suggests that the policy measure of the new-type urbanization reform, in which the central and western regions are gaining more attention and support, is conducive to narrowing the urban-rural gap.
