宏观经济波动、公司规模和资本结构选择

中国宏观经济2006—2008年的波动为资本结构自然实验法研究提供了条件。选择该期间行业内资产规模最大和最小的中国A股上市公司作为研究样本,实证研究了宏观经济波动对不同规模上市公司资本结构选择的影响。研究发现:宏观经济波动对大规模上市公司和小规模上市公司的资本结构影响存在显著差异,不同规模的公司均显著改变了其融资行为;宏观经济状况和公司规模是上市公司资本结构选择的重要因素。

Successful eco‐innovators: Exploring the association between open inbound knowledge strategies and the performance of eco‐innovative firms

The main purpose of this paper is to analyse the association between open inbound knowledge strategies and the performance of eco‐innovative firms in the food and beverage industry. We propose a mixed framework based on the eco‐innovation literature and the open innovation approach. We consider the characteristics in a traditional sector based upon a resource‐based perspective. Three types of firms are distinguished in terms of their sales growth in the Spanish food industry from the least to the most successful eco‐innovators. Using multinomial logistic regression models, it is shown that the diversity of collaborators (breadth of external sources of knowledge) and joint adoption of product and process eco‐innovations are positively associated with the probability of achieving high sales growth. Moreover, we find an inverted U‐shaped relationship between the breadth of the external search and firm performance, but only for the group of the most successful firms. Moreover, operational flexibility, knowledge‐based capabilities and company size are also positively related to the group of successful eco‐innovators.     

Environmental policies,national culture,and stock price crash risk: Evidence from renewable energy firms

This study investigates the impact of country‐level environmental performance and national culture on the stock price crash risk of renewable energy firms. Employing a large sample of 626 renewable energy firms across 31 countries, we find a significant nonlinear relationship between country‐level environmental performance and crash risk. National culture dimensions are found to strongly predict the crash risk of renewable energy firms, particularly after the global financial crisis. On the contrary, national culture dimensions and environmental policies are observed to not exert any significance in explaining the crash risk of fossil fuel firms. Our results are robust with respect to alternative measures of stock price crash risk and the endogeneity of national culture dimensions. Overall, the findings of this paper contribute to the environmental economics literature by providing new evidence regarding the role of societal and environmental factors in explaining the stock price crash risk of energy firms.     

Corporates' strategic responses to economic policy uncertainty in China

Using a novel news‐based index of economic policy uncertainty, this paper studies the impact of economic policy uncertainty on corporate strategic positioning and corporate risk in China from 2009 to 2015. The study also investigates the impact of corporate strategic positioning on corporate risk. The results show that corporate strategic positioning and economic policy uncertainty have a significant positive impact on corporate risk. The results also explain that economic policy uncertainty increases the market risk of the firms irrespective of their corporate strategy. However, it increases the business risk of prospector firms and decreases the business risk of defensive firms. The study may help the firms to formulate and improve their strategic positioning while considering economic policy uncertainty. Our results are robust to alternate proxies of economic policy uncertainty and corporate risk.     

会计师事务所转制对审计质量的影响研究——来自上市公司的经验证据

通过分析2008-2012年A股上市公司相关数据,研究会计师事务所转制对于审计质量的影响,结果显示：特殊普通合伙制会计师事务所的审计质量高于有限责任制会计师事务所的审计质量;转制后会计师事务所的审计质量高于转制前会计师事务所的审计质量,但是转制对审计质量的提高有一定的不同步性。研究结论为转制政策的合理性提供了证据支撑,也为其他中小型会计师事务所改制提供了必要性方面的经验依据。     

Innovation in R&D service firms: evidence from the UK

Research and Development (R&D) service firms make significant contributions to innovation in other businesses. The extant literature considers these firms a homogenous sub-group of Knowledge Intensive Business Service firms (KIBS). The objective of this study is to investigate how R&D service firms innovate and the variety of innovation practices within these firms. Employing data from semi-structured interviews with senior managers from 32 UK-based R&D service firms, we suggest that there are two different modes of innovation: in the first mode, R&D service firms innovate similarly to KIBS whose innovation is ad-hoc in nature and driven by customers’ requests; another group of R&D service firms innovate like New Technology-based Firms (NTBFs) relying more on structured in-house R&D activities.     

Is working capital management value-enhancing through alleviating financial constraints? Evidence from Chinese non-listed firms

Financial factors have been found highly important in influencing firms’ real activities and in promoting aggregate growth. Yet, the linkage between finance and firm-level total factor productivity (TFP) has been overlooked in the literature. I fill this gap using 147,310 non-listed Chinese firms over the period 1999–2007 to estimate a TFP model augmented with working capital. I find that TFP is strongly and significantly associated with working capital for private and foreign firms, but not for SOEs. More specifically, an increase in working capital has a negative (positive) effect on TFP in firms with positive (negative) working capital. Furthermore, highly external financial constrained, highly internal financial constrained, under-developed institutional regions and small size private and foreign firms are more sensitive to working capital.
