西部开发与民族地区发展理论研究之进展

民族地区的发展问题一直受到学界同仁的高度关注,这与党和政府高度重视民族地区发展和各民族共同繁荣的政策是密切关联的。尤其是西部大开发战略实施10年来,学界对民族地区发展的关注程度进一步提升。在学界相关研究中,民族地区发展问题与西部大开发政策总是有着深刻而内在的关联。按照学界研究所关注的不同侧重点,把研究理论划为经济建设、文化状况和政策管理等三个维度的理论研究,而实际上这三个维度是不能截然分开的。学界的相关研究成果对指导民族地区的经济社会发展和生态环境改善具有积极的建设价值。

从改革发展成果公平分享角度看现行的财政转移支付制度

有人认为分税财政体制导致了基层财政困难和地区间差距的日益扩大,但实际上分税制只是有关政府间公共财政资源的初次分配,其目标是财政分权而不是均等化公共物品,只要存在地区经济发展的不平衡,必然形成地方政府间财政能力的不平衡,真正以财政均衡为目标的制度是财政转移支付制度,财政转移支付制度才是财政均衡的制度保证。不可否认,政府间财政能力不均衡是经济发展不平衡,包括东中西部区域经济发展不平衡及城乡经济发展不平衡的重要原因之一,是改革发展成果公平分享的制度性障碍。因此,     

Product market competition and cost stickiness

Extant literature on cost stickiness has focused on how firm-specific characteristics affect the asymmetric cost behavior. In this paper, we explore how a firm’s operating environment affects the firm’s cost stickiness. Specifically, we examine the effect of product market competition on cost stickiness since a firm’s investment and cost retention decisions partly depend on how the firm interacts with its rival firms in the product markets. Using two firm-level text-based product market competition measures extracted from management disclosures in firms’ 10-K filings (Li et al. in J Account Res 51(2):399–436, 2013; Hoberg and Phillips in Rev Financ Stud 23(10):3773–3811, 2010; J Polit Econ, 2015), we find strong evidence consistent with cost asymmetry increasing in competition after controlling for known economic determinants of cost stickiness. In additional analyses, we also find that the effect of product market competition on the degree of cost stickiness increases in firms’ financial strength, likely because management in financially stronger firms has more resources for investment expenditures in spite of a sales fall. We also find that cost stickiness is increasing in competition if management is optimistic about future demand, whereas competition is not associated with cost asymmetry if management is pessimistic about future demand. Finally, we find that the relationship between competition and cost stickiness, although statistically insignificant at conventional levels, is more pronounced for single-segment firms relative to multi-segment firms.     

高技术制造业与高技术服务业协同集聚的经济增长效应

基于中国省级面板数据,利用空间面板模型和面板门槛模型,探究高技术制造业与高技术服务业协同集聚的经济增长效应。结果表明：区域间产业集聚特征差异显著,高协同集聚主要集中在东部沿海地区,低协同集聚主要集中在西部地区。经济增长水平、高技术制造业与高技术服务业协同集聚水平均具有显著空间正相关性,二者协同集聚有助于促进区域经济增长。协同集聚的经济增长效应存在双重门槛,当高技术制造业集聚度和高技术服务业集聚度均介于第一、二门槛之间时,产业协同集聚的经济增长效应最强。仅少部分省域两产业集聚度介于第一二门槛之间,能够有效发挥协同集聚对经济增长的推动作用。     

Productivity dynamics and the cleansing effect of two recessions: Evidence from the manufacturing sector in Korea

In general, recessions provoke the exit of a greater number of firms from the market. Less productive firms are more likely to exit and release their former resources to the remaining, more productive firms. The present study investigates two recessions in Korea: the Asian financial crisis and the global financial crisis. The main objective of the present study is to analyse the process of creative destruction in a recession, specifically the cleansing effect. We measured total factor productivity using micro‐level manufacturing plant data from 1993 to 2013. We decomposed the source of the changes in total factor productivity to measure the cleansing effect in two large recessions. During the first recession in the 1990s, there was no evidence to support a cleansing effect hypothesis. In contrast, during the second recession in the 2000s, there was evidence of a cleansing effect. In addition, we found differences in market selection criteria in the two recessions; by the second crisis, the market selection criteria had changed to enable a more conducive environment for the creative destruction process.

低碳经济发展激励机制研究

我国发展低碳经济需要兼顾经济增长与节能减排的双重任务。通过建立多任务委托代理模型,对政府激励和引导企业通过发展低碳经济最优化经济效益和节能减排效益的激励契约进行了分析。结果表明,政府一方面应根据企业可观测的努力程度来制定不同的激励契约,另一方面需要考虑不同任务间的相关性对企业激励的影响。
