本文研究了银行竞争程度的变动对制造业上市公司融资约束大小的影响。本文将我国制造业A股上市公司作为样本,建立多元回归模型验证银行竞争形势的加剧是否会影响企业所面临的融资约束。本文认为制造业A股上市公司面临显著的融资约束,而且银行竞争与企业所面临的融资约束之间呈现U型关系,即随着银行竞争的加剧,融资约束呈现先放松后收紧的趋势。  相似文献

This work presents key insights on the model development strategies used in our cross-learning-based retail demand forecast framework. The proposed framework outperforms state-of-the-art univariate models in the time series forecasting literature. It has achieved 17th position in the accuracy track of the M5 forecasting competition, which is among the top 1% of solutions.  相似文献

Showrooming, a phenomenon in which customers use brick-and-mortar stores to assess products and then purchase them from online retailers (o-retailers) for lower prices, is considered a great threat to traditional retailers (t-retailers). To combat showrooming, many t-retailers have executed price matching which enables customers to pay o-retailers' lower prices for the identical product. To avoid direct competition with t-retailers who execute price matching, many o-retailers have begun to sell differentiated products from t-retailers, which weakens the information advantage to customers from practicing showrooming. Motivated by these observations, we construct a duopoly game, where a t-retailer and an o-retailer sell products in a same category, to study the profitabilities of product differentiation and price matching in the context of showrooming. The results show that in the scenario without price matching, the o-retailer is likely to benefit from product differentiation only when the o-retailer's differentiated product is more popular with customers than the t-retailer's product. However, in the price matching scenario, the o-retailer also has the opportunity to benefit from product differentiation when the o-retailer's differentiated product is less popular with customers than the t-retailer's product, and product differentiation can be a win-win strategy for the two retailers under certain conditions. Considering the o-retailer's product differentiation decision, the t-retailer is only likely to execute price matching if the non-digital attributes of the product category sold by two retailers are not very obvious.  相似文献

We study how local leaders matter for economic growth by examining the impacts of exogenous transfers of leaders across China’s provinces on land transactions in the primary market. We find that new provincial leaders attract investment in industrial land from the provinces of their previous positions. The leaders’ impacts are greater when their freedom to deploy their business connections in the land market is greater. More importantly, we find evidence of positive impacts of land transactions on economic growth, which should bode well for the careers of the local leaders, albeit there is some evidence of rent seeking among officials especially when they are too old for further promotion.  相似文献

Family firms bear two types of agency costs, including type I and type II agency problems, in corporate environmental practices: (1) Outside executives at family firms hesitate to engage in environmental strategies, which can lead to drops in profits; (2) Controlling families employ opportunistically environmental management to achieve their interests. We argue that a primary cause for the agency problems lies on ineffective internal corporate governance at family firms, which can cause loss of managerial (or power) balance between outside executives and family executives. Our findings show that family firms with ownership and strategic control (FSC), which family executives and outside executives monitor and constrain each other, can achieve the highest environmental performance. Moreover, external controls, including product market competition and provincial environmental regulations, substitute effective internal control of FSC. The environmental performance premium of FSC is more prevalent when the production market competition is lower. Family firms with ownership, operational, and strategic control (FOSC) can achieve higher environmental performance within a province with more stringent environmental regulations.  相似文献

Haze pollution has become a new threat to China's sustainable development, but it may be that local government behaviour can play an important role in the prevention and control of pollutants. A dynamic spatial autoregressive (SAR) model is used to study the relationship between local government competition and haze pollution. To further explore the indirect impact of factor market distortion on haze pollution and control potential endogeneity problems, a newly developed intermediary effect model that incorporates the characteristics of the generalized method of moments (GMM) is utilized to explore how factor market distortion indirectly affects haze pollution. The research results show that regional haze pollution in China is characterized by significant spatial correlation, and local government competition has a positive impact on haze pollution; that is, local government competition exacerbates haze pollution. In general, local government competition not only directly leads to an increase in haze pollution but also further intensifies it by distorting the local factor market, and the intermediary role of factor market distortion is approximately 7.04%. The results of the regional inspection found that competition among local governments in the eastern region did not lead to haze pollution, and distortion of the factor market did not exist as an intermediary effect. However, both direct and intermediary effects are significant in the central and western regions. Therefore, an official performance appraisal system that includes ecological constraints should be established to guide the benign transformation of local government competition, and an environmental management mechanism must be developed for joint prevention and control to reduce haze pollution. In addition, the free flow of factors and marketization are equally important.  相似文献

从世界范围来看,房地产税在地方税体系建设中具有不可替代性,但税制设计的特殊性和征收过程的复杂性也使其备受争议。本文着眼于从理论和实践结合的角度,较为系统地分析世界房地产税发展中已取得的共识、仍存在的争论,以及对中国具有启发性的结论。首先,通过分析房地产税作为地方主体税种的优势解释其建立和发展的必要性。随后从两个方面分析房地产税征管中存在的矛盾、已有对策及其有效性:其一,以核心指标为基础建立税收收入分析框架,实现对政策行政因素的分析;其二,从纳税人的厌税情绪和对公平性的冲击两个方面实现对社会经济因素的分析。最后,尝试得出房地产税征收和改革中应遵循的共识性路径,并总结像中国一样的发展中国家应额外关注的关键点。  相似文献

基于2011~2017年我国A股重污染型上市公司经验数据,实证检验了领导干部自然资源资产离任审计对企业绿色并购行为的影响,研究发现:领导干部自然资源资产离任审计可显著促进辖区内企业实施绿色并购;而当地区市场竞争程度越高时,越会抑制企业在领导干部自然资源资产离任审计试点实施背景下的绿色并购扩张行为;进一步地,企业绿色并购会显著提高企业价值,且这一影响对并购后当年的企业价值影响最为显著;基于异质性分析方面,领导干部自然资源资产离任审计会约束不同产权性质企业的环境治理行为,促进其采取绿色并购,实施绿色发展;同时领导干部自然资源资产离任审计会更有利于东部地区企业实施绿色并购,而对中西部地区的企业影响不明显。  相似文献

基于2005年全国1%人口调查、2010和2012年“北京大学中国家庭和个人跟踪调查”(CFPS)数据,本文以姓氏集中度代理宗族文化强度,研究并购双方所在地区宗族文化差异对企业并购收益的影响,发现宗族文化差异越大企业并购收益越高.进一步研究表明宗族文化不会显著影响地区内个体的思维方式或价值观念,但宗族的排外性使强宗族文化地区企业掌握了独有的社会关系网络和社会资本,收购强宗族文化地区企业有助于外地企业进入地方社会网络,吸收地方社会资本,增加市场竞争优势.基于这一现象构建投资策略,收益远超市场表现.本文研究结果对构建投资策略、企业并购决策具有价值.  相似文献
