以系统论思想为指引,遵循要素-结构-功能的分析范式,从科技创新治理能力发展的水平结构和外部性结构两个方面入手,就科技创新治理能力对科技创新治理绩效的作用机理进行逻辑推演。结合中国科技创新治理体系治理能力发展现状,对治理绩效低下的形成机理进行系统探讨,结果表明:科技创新治理能力的强度结构是决定科技创新治理绩效的关键,而科技创新治理体系整体治理能力水平偏低、内部结构失衡是导致现行科技创新治理绩效低下的根源。与此同时,科技创新治理能力外溢效应在不同方向上的非对称性加剧了科技创新治理能力的结构性失衡,阻碍了科技创新治理能力的整体性提升,抑制了科技创新治理绩效有效增长。因此,应加快转变治理理念,逐步构建以“创新链”为核心的现代科技创新治理模式;增强微观治理能力,构建开放包容的科技创新管理服务体系;提升中观治理能力,实行科技创新管理机构垂直管理;优化治理环境,将知识产权法律制度环境和科技交易市场环境营造纳入科技创新管理服务体系,逐步构建与现代科技创新治理理念相匹配的科技创新管理部门地方政府官员政绩考评体系。 相似文献

This study investigates how different types of corporate philanthropy impact employees' life satisfaction. Grounded in signaling theory, we explore and clarify the nuances among three types of corporate philanthropy values: the absolute value of corporate philanthropy, the value of a firm's corporate philanthropy relative to its past level, and the value of corporate philanthropy relative to the firm size. Results of multilevel analyses on a large scale sample with 218 firms and 2,261 employees at two time points reveal that: the absolute value of corporate philanthropy positively influences employees' life satisfaction; the value of a firm's corporate philanthropy relative to its past philanthropy negatively impacts employees’ life satisfaction; and the value of corporate philanthropy relative to the firm size positively affects employees' life satisfaction. The results indicate that the influences of corporate philanthropy on employees' life satisfaction vary depending on the evaluation benchmarks. Firms may benefit by taking their size and past philanthropy into consideration when making corporate philanthropy investment decisions. 相似文献

We examine differences in information content between order submission sizes and trade sizes by U.S. equity traders. Increasing (decreasing) order submission (trade) size is reflective of information. The result suggests that better-informed traders want to trade in a large size, but that they engage in stealth trading practices or break larger orders into smaller sizes in order to conceal information. While prior studies tend to narrowly focus on trade executions at the market-centre level, our findings indicate that order submission size varies significantly from trade size and that both sizes are informative about future prices, albeit in an inverse manner. 相似文献

Intelligent sharing bicycle has been a new fashion in China and appeals to more and more tourists. To better understand the experience of tourists traveling on sharing bicycle, this study explored the influence of perceived benefit of sharing bicycle on different perceived experiences, including escape, entertainment, esthetic and educational experiences. The relationships between these experiences and perceived satisfaction were also tested. An effective questionnaire survey was conducted for 296 tourists in Chengdu, China. The results of the study show that perceived benefit significantly relates to all the four dimensions of experience. However, only entertainment and esthetic experience seem to affect tourist satisfaction in this context. The relationship among educational experience, escape experience and tourist satisfaction are insignificant. Theoretical and practical implications of the study results are discussed for further research. 相似文献

Data envelopment analysis (DEA) has been constantly used to measure the technical efficiency of decision-making units (DMUs). However, the major problem of traditional DEA methods is that they do not consider the possible intermediate effects. Recently, many papers have applied network DEA models to evaluate the efficiency scores. However, the linking activity of DMUs is still hard to be recognized. Hence, we employ DEMATEL to obtain the linking activity of DMUs. Our empirical research shows that the proposed method can soundly deal with the purpose of identifying the relationship between variables and derive the reasonable result in network DEA. 相似文献

We examine the relationship between environmental regulation and spatial development in China. Exploiting changes in national pollution standards for three industries, ammonia, paper and cement, we measure the impact of environmental regulation on industry productivity. Our results suggest that national pollution standards do not affect industry productivity, but they reallocate productivity spatially. We show that regulated industries located in developing cities increase their productivity compared to similar industries in other cities. This means that environmental regulation affects the spatial distribution of technology in China and might influence long‐term spatial development by reducing geographical disparities. 相似文献

本文从理论和实证两个维度检验了地方政府环境支出行为的空间策略互动的传导机制。结果表明,环境支出存在明显的空间策略互动与时间滞后效应。其表现为相邻省级地区之间环保财政支出行为的互相模仿和路径依赖。外商直接投资和财政分权并不是导致地区间环境支出“逐底竞争”的直接原因。在构建多维度政绩考核体系来引导政府财政支出竞争的同时,建立地区间环境支出的协调机制和对外开放等途径,有利于实现均衡和绿色发展。 相似文献
