数字化转型与企业价值——基于文本分析方法的经验证据

本文基于中国上市企业2007-2019年数据,借助爬虫技术归集企业年报中的"数字化转型"关键词,实证检验数字化转型对企业价值的影响及其渠道机制.研究发现,数字化转型能够显著提升企业的价值水平.异质性检验结果发现,企业数字化转型对于"国有企业-非国有企业"的价值水平都具有显著的正向驱动作用,但对于非国有企业而言,这种促进作用更为明显;企业数字化转型对"高科技企业-非高科技企业"的价值都具有显著的正向促进作用,对于其中的高科技企业而言,这种促进作用更为明显.从渠道机制检验来看,企业数字化转型能够有效提升技术创新能力、增强要素配置水平并对风险具有更强的可控力,这些因素的改善,都有助于企业价值水平的增加.

自我监控人格对创新绩效的影响:基于社会信息处理理论

中国文化背景下,人们更容易表现出高自我监控特征,但目前对自我监控人格与创新绩效的研究还相对不足.基于社会信息处理理论,采用25家企业441个员工的调研数据,探究自我监控人格对创新绩效的影响机制.研究结果表明,自我监控人格对创新绩效存在显著驱动作用;组织创新氛围感知、员工个体创造力以"串联"结构在自我监控人格与创新绩效的关系间发挥链式中介作用.上述发现扩展了自我监控人格与创新绩效间作用路径,为企业管理人员正视员工自我监控人格以促进员工创新绩效提供了一定启示.     

多源程序公平气氛影响个体创造力的跨层次效应

从来源角度探讨组织公平，是对现有多维度公平理论框架的重要补充。基于动机理论中的自我决定理论，以来自20个组织55个团队的250份团队领导与成员配对问卷为样本，探索中国情境下多源程序公平气氛对个体创造力的跨层次影响及作用机理。研究结果显示:不同来源（来源于领导和来源于组织）的程序公平气氛均对个体创造力有显著正向影响；心理授权在来源于领导的程序公平气氛和来源于组织的程序公平气氛对个体创造力的跨层次影响中均发挥中介作用；权力距离在来源于组织的程序公平气氛与员工心理授权的关系间起调节作用，即权力距离越高，来源于组织的程序公平气氛对员工心理授权的影响越强。     

The role of cultural values in green purchasing intention: Empirical evidence from Chinese consumers

Environmental problems, especially in the case of water and air pollution, are the harmful result of the overconsumption of fossil fuels as well as various forms of industrial sewage water discharge. Recently, growing environmentally friendly purchasing behaviour of consumers has become regarded as an effective method for alleviating such environmental problems. Due to concerns regarding the natural environment, consumers have increasingly begun to exhibit favourable attitudes towards environmentally friendly products, and as a result, are more likely to purchase “green” products. However, green purchasing behaviour of consumers varies across different nations and cultures. This study aims to reveal how Chinese cultural values (specifically, the Doctrine of the Mean) influence green purchasing intention of Chinese consumers. As the lifestyles of consumers will be deeply affected by their cultural values, this study examines the mediating effects of the four dimensions of Chinese lifestyle have on consumers. At the same time, environmental knowledge is considered as a moderating variable in order to investigate the relationship between the Doctrine of the Mean and green purchasing intention. The study’s data were collected from Chinese consumers. Empirical results reveal that such Chinese cultural values are positively associated with green purchasing intention, and that three dimensions of consumer lifestyle (namely leadership, cost consciousness and development consciousness), are all found to play mediating roles in the relationship between the Doctrine of the Mean and green purchasing intention in Chinese consumers. The moderating effects of environmental knowledge are exhibited in the influence of leadership as well as development consciousness on green purchasing intention. The study’s findings have theoretical implications for understanding green purchasing intention as well as behaviour of Chinese consumers further. The study’s findings also present practical implications for how to promote green purchasing intention in Chinese consumers better.     

Beyond symbolic and substantive: Strategic disclosure of corporate environmental information in China

Under increasing regulatory pressure to disclose environmental impacts, corporate environmental information disclosure (EID) is becoming more prevalent. However, the motives for EID and disclosure approaches (i.e., symbolic or substantive) remain controversial. Using a sample of data for 742 listed manufacturing firms in China across 3 years, we provide evidence to show that the level of EID is significantly positively associated with a firm's advertising intensity and that firms in moderately competitive industries have a higher propensity for adopting an EID‐based differentiated strategy than firms in stronger or weaker competitive industries. We also find that firms that are more sensitive to environmental issues strategically understate their environmental impact when directly facing consumers. Our results suggest that the implementation of corporate EID is strategic and that firms have strong market motives, even under regulatory pressure to demonstrate legitimacy. We discuss this study's contributions to research on EID theory and implications for strategic EID management.     

Strategic networks and new product performance: the mediating role of ambidextrous innovation

In this study we examine the relationship between strategic networks and new product performance from the perspective of ambidextrous innovation (i.e. combining exploratory innovation and exploitative innovation) using a sample of 323 manufacturing firms in the transitional economy of China. Our empirical analyses present several interesting findings: (a) strategic networks are positively related to firms’ new product performance; (b) ambidextrous innovation has a positive effect on firms’ new product performance – that is, the combination of exploratory innovation and exploitative innovation positively affects the firm's new product performance, while the lack of balance between exploratory innovation and exploitative innovation negatively affects the firm's new product performance; and (c) ambidextrous innovation mediates the relationship between strategic networks and new product performance. Our findings provide scholars and managers with a better understanding of the key role played by the simultaneous adoption of exploratory and exploitative innovation in the relationship between strategic networks and new product performance.     

基于冠层光谱和BP神经网络的水稻叶片氮素浓度估算模型

[目的]快速、准确地诊断水稻叶片氮素营养状况,为水稻氮肥精准管理提供依据。[方法]以江西省农科院8种不同施肥处理的晚稻为研究对象,于主要生育期同步测定了水稻冠层光谱反射率及叶片全氮浓度(Leaf Nitrogen Concentration,LNC),系统分析了原始光谱反射率、一阶微分光谱、"三边"参数以及由350～1 350nm两两波段组合的差值(SD (Rλ1,Rλ2))、比值(SR (Rλ1,Rλ2))及归一化(ND(Rλ1,Rλ2))光谱指数与水稻LNC的相关关系,筛选出敏感参数,并以之为自变量构建了水稻LNC的传统预测模型,另外构建不同指标个数的多元线性与BP神经网络模型,并对模型进行验证。[结果](1)水稻LNC与一阶微分光谱在751nm处的相关性最高(r=0. 822);(2)"三边"参数中的红边面积SDr与LNC的相关性较高(r=0. 687);(3) 750nm附近的红边波段与近红外波段差值组合、550nm附近的绿光波段与近红外波段的比值及归一化差值组合与水稻LNC的相关性较高,以SD (R752,R751)、SR (R534,R1 350)和ND (R534,R1 349)表现最好,相关系数分别为0. 827、-0. 790和0. 788;(4)传统回归模型中以SD(R752,R751)构建的一元线性模型最佳(RC2=0. 665、RV2=0. 750、RMSEV=0. 4%、RPD=2. 034);(5)利用5个指标((R'751、SDr、SD (R752,R751)、SR (R534,R1 350)、ND (R534,R1 349))经逐步回归筛选出的2个指标SD ((R752,R751)和SR (R534,R1 350))构建预测水稻氮素的BP神经网络模型,预测效果最佳,其验证参数值分别为R2=0. 859、RMSEV=0. 302%和RPD=2. 669。[结论]基于单指标构建的传统线性模型计算过程简单但精度略低,而基于2个指标(SD (R752,R751)、SR (R534,R1 350))构建的BP神经网络模型预测精度高于该2指标构建的多元线性模型,表明在指标适合的情况下,BP神经网络对氮素具有较好的预测能力,是一种快速准确估算水稻叶片全氮浓度的方法。     

The heterogeneous relationship between board social ties and corporate environmental responsibility in an emerging economy

Firms in emerging economies are faced with multiple, incompatible institutional forces in their environmental activities. Which of these forces will be dominant and instantiated within an organization is partly determined by the social relationships that a firm maintains with external actors. This paper investigates the relationship between board social ties and the level of environmental responsibility undertaken by firms in China, an emerging economy, by categorizing board social ties into three types in terms of the three isomorphic forces in the institutional field (coercive, normative and mimetic). Drawing on institutional and agency theories, using a sample of listed firms in environmentally sensitive industries, and a generalized least squares regression method, the results provide empirical evidence that ties that are linked to coercive and normative forces (i.e., political organizations and universities) are related to a higher level of environmental responsibility; however, those that are linked to mimetic forces (i.e., industrial peers) have a negative association with environmental responsibility, which is mitigated by CEO power. These findings suggest that the heterogeneous effects of board social ties on environmental responsibilities experienced by firms in a context of environmentalism are at an early stage.
