基于跨国并购的创新网络嵌入、网络异质性与创新质量研究

区别于现有研究通常将跨国并购视为一个“事件”研究其对并购企业技术创新的影响，基于创新网络视角，文章采用中国上市公司数据，通过关系嵌入和结构嵌入两个维度探讨基于跨国并购的国外创新网络对创新质量的影响机制。研究发现，通过跨国并购嵌入创新网络的直接联系促进了创新质量提升，间接联系和结构洞对创新质量产生了显著的抑制效应。网络异质性对基于跨国并购的创新网络嵌入与创新质量具有倒U型调节作用，在网络异质适度阶段，网络异质性正向调节基于跨国并购的创新网络嵌入的创新质量效应，在网络异质过度阶段，网络异质性具有负向调节效应。研究发现为新兴经济体企业实施跨国并购，有效嵌入国外创新网络，配置创新资源，提升创新质量，提供了有价值的参考。     

Corporate social responsibility in emerging economies: Investigating firm behavior in the Indian context

Scholars have questioned the appropriateness of using a western‐centric framework to investigate corporate social responsibility (CSR) in emerging economies. This study assesses the appropriateness of using such a framework in one emerging economy—India. More specifically, the drivers of CSR and their impact on firm‐level CSR activity in the Indian context are investigated and compared with those in developed economies. Content analysis of 369 CSR policy statements of publicly traded Indian firms revealed the factors that drive CSR activities of Indian firms are similar to those found in developed economies. However, the ways firms respond to the drivers of CSR are surprisingly different in the Indian context, and these differences can be traced to attributes of the Indian socio‐cultural context. Implications and recommendations for future research conducted in India, and in other emerging economies, are offered.     

Ad hoc网络中基于多波束天线的集中式低时延调度算法

UxDMA算法是一种高效的集中式算法，是用于时分多址、频分多址和码分多址信道分配的统一算法。在UxDMA的基础上，利用多波束天线的多波束形成能力，针对低时延定向ad hoc网络提出了一种集中式调度算法——CLSM(Centralized Low-delay Scheduling Algorithm Based on Multi-beam Antennas)。CLSM通过不同时延等级限制的报文来比较着色后发送链路的优先级，优先选择高优先级链路传输。通过仿真验证了CLSM的性能：与UxDMA相比，该算法在多时延限制的发送端调度中表现出了更好的吞吐量和时延性能。     

Conceptualizing businesses as social actors: A framework for understanding sustainability actions in small‐ and medium‐sized enterprises

Small‐ and medium‐sized enterprises (SMEs) can play a crucial role in advancing environmental and social well‐being. Yet various—often conflicting—explanations have been offered to clarify why SMEs pursue sustainability. Some arguments foreground possibilities of profit maximization, whereas others emphasize individual values and convictions. Research supporting such contradicting explanations is often biased towards large enterprises or small, innovative frontrunners. In this article, we examine the underlying drivers of social and environmental interventions of SMEs by exploring empirical data from a survey of over 1,600 Canadian SMEs and complementary in‐depth interviews. We argue that sustainability actions of SMEs can be understood by viewing these firms as social actors—organizations that are shaped by individual values, internal and external interpersonal relationships, and are embedded in a social environment. This conceptualization directs attention to the full range of factors that shape sustainability engagement of SMEs and highlights frequently overlooked forms of sustainability‐oriented actions.     

中国数字经济空间关联网络及其影响因素分析

基于2013年和2020年29个省的数据，用因子模型测算各省数字经济发展水平，在此基础上使用修正引力模型构建数字经济空间关联网络，并深入分析此网络特征。结果表明：中国数字经济发展水平存在差异，东部地区高于中西部地区；中国数字经济空间关联网络密度不断增大；北京、山东、江苏一直是网络的重要输出省份，近年来西部地区在网络中的作用越来越明显；地理位置相邻、贸易开放度和产业结构对网络的形成有显著影响。     

基于机器学习的斜坡堤越浪量预测方法研究

针对斜坡堤越浪量预测方法,分别建立集成神经网络(ensemble neural network,ENN)、随机森林(random for-eset,RF)和支持向量回归机(suppport vector regression,SVR)3种机器学习模型对斜坡堤越浪量进行预测,并利用决定系数R2和均方根误差RMSE来评估模型性能.最后,对3种模型的性能进行分析.结果显示,集成神经网络模型的决定系数R2和均方根误差RM S E分别约为0.96和0.0018,随机森林模型的决定系数R2和均方根误差RMSE分别约为0.97和0.0014,支持向量回归机模型的决定系数R2和均方根误差RMSE分别约为0.94和0.002.对比发现,3种模型的决定系数都达到0.9以上,都具有较高的预测精度,随机森林相比其他两个模型精度更高.     

Exploring the effect of buyer engagement on green product innovation: Empirical evidence from manufacturers

In this study, we are interested in how export firms organize knowledge management and increase product innovation performance. Prior studies have concluded that knowledge transfer from external actors leads to operational performance outcomes; others have questioned the positive influence of buyer-driven knowledge transfer activities on innovation performance. Drawing on absorptive capacity, we aim to offer a better understanding, how export firms as recipients of knowledge resources, organize their internal capabilities in order to realize firm-level product innovation. This empirical study examines the interplay of buyer-driven knowledge activities, resource acquisition and combining, and product innovation outcomes in the context of Pakistani export firms. Drawing on survey data from 239 export-manufacturing firms, we test hypotheses using structural equation modeling. Our findings show that buyer-driven knowledge transfer activities play a crucial role in enhancing export firms in absorbing and combining resources that lead to product innovation. The pragmatic suggestion of the research suggests that managers look closely at developing a culture of involvement with their buyers that promotes the development of knowledge resources. The results of this study have research, policy, and managerial implications.     

Exploring the links among corporate social responsibility,reputation, and performance from a multi-dimensional perspective

This study examines the links among corporate social responsibility (CSR), reputation, and performance in hotel companies from a multidimensional perspective. Data were collected from 322 hotels in China and partial least squares equation modelling (PLS-SEM) was employed for a causal-predictive analysis. Study results reveal that CSR practices influence hotel reputation as seen from both international and local perspectives. CSR and reputation influence performance dimensions (accounting-based performance, market-based performance, and non-financial performance) differently. The research findings offer specific theoretical and practical implications for hotel managers.     

Medicaid and long‐term care: The effects of penalizing strategic asset transfers

Medicaid provides a critical source of insurance for long‐term care, and individuals may strategically offload assets (typically to children) to meet the means‐tested eligibility requirement. In this article, we quantify the extent of such behavior using variation in the penalty for improper parent‐to‐child transfers induced by the Deficit Reduction Act of 2005. We estimate difference‐in‐differences models based on the hypothesis that only individuals with high levels of nursing home risk (high risk) will alter transfers because of the Act. We find that over a 2‐year horizon, high‐risk individuals reduced transfers to children on the extensive margin by 11 percent and that the average total amount of transfers decreased by $4,860. The results hold only for coupled respondents. We also conduct a triple‐differences analysis to examine heterogeneity with financial literacy and find that even those with a low level of financial literacy responded to the penalty.     

How does corporate social responsibility affect financial performance,financial stability,and financial inclusion in the banking sector? Evidence from Pakistan

This paper examines the impact of corporate social responsibility (CSR) on the financial performance, financial inclusion, and financial stability of the banking sector, focusing on annual data for 20 Pakistani commercial banks for the period 2008–2017. The results suggest that CSR, as well as age and size, has a positive impact on all three factors. However, high levels of leverage reduce financial inclusion and financial stability, while financial inclusion is also negatively associated with the tangibility of assets.
