Government Credit,a Double‐Edged Sword: Evidence from the China Development Bank

Using proprietary data from the China Development Bank (CDB), this paper examines the effects of government credit on firm activities. Tracing the effects of government credit across different levels of the supply chain, I find that CDB industrial loans to state‐owned enterprises (SOEs) crowd out private firms in the same industry but crowd in private firms in downstream industries. On average, a $1 increase in CDB SOE loans leads to a $0.20 decrease in private firms' assets. Moreover, CDB infrastructure loans crowd in private firms. I use exogenous timing of municipal politicians' turnover as an instrument for CDB credit flows.     

TECHNOLOGICAL CHANGE AND DEMAND FOR SKILLS IN DEVELOPING COUNTRIES: AN EMPIRICAL INVESTIGATION OF THE REPUBLIC OF KOREA'S CASE

There are few studies that directly address the upskilling issues in developing countries. Since theoretical analyses of these issues usually yield different results, upskilling in developing counties, and the factors of upskilling, if any, are rather empirical questions. This study shows that upskilling that occurs in developed countries in terms of the ratio of the number of white‐collar workers to that of blue‐collar workers also occurred in the Republic of Korea, one of developing countries. Increasing demand for highly‐skilled workers reflected in their employment and wage shares can be largely explained by “within industry’ shifts, not by “between industry” shifts, especially in the manufacturing industry. To further investigate the causes of these shifts, changes in white‐collar shares are regressed on the capital‐output and R&D‐sales ratio. Estimated coefficients are all positive, suggesting capital‐skill complementarities and skill‐biased technological change.     

中国城区公园绿地面积与人口数量、建设 用地面积演变的脱钩关系研究

公园绿地是满足市民“美好生活需求”的优质公共 绿色空间，并受建设用地的支撑与约束，科学认识其与人口、 建设用地相互关系是实现城市高质量发展的关键点。引入“脱 钩”理论及模型，将“公园绿地与人口、建设用地”联动，系 统分析1996—2016年三者耦合特征及整体复杂关系。研究 表明：1)公园绿地建设与人口协调关系严峻，与“以人民为 中心”导向脱节；公园绿地与建设用地处于“以土地推绿地” 的“挂钩”增长态势；2)从整体联动视角看，约1/3城市的公 园绿地与人口、建设用地整体统筹建设不协调，公园绿地发展 面临“过度依赖建设用地”困境，亟须转变成“因人口制绿， 以存量建设用地为基”建设
