This article tests the hypotheses of convergence to a single level of total factor productivity (TFP), and a steady state of TFP growth rate in China’s agricultural sector. Based on multilateral TFP estimates we found that China’s agricultural sector has rebounded in recent years from a slower TFP growth in the 2005–2007 period. While convergence test results confirm a “catch-up” effect that provinces with lower TFP levels tend to grow faster than others, estimated rates of β convergence are conditional on how we capture the heterogeneity effect across regions. The rates of β convergence range from 0.016 to 0.039 under different model specifications. Estimates show that higher growth rates of educational attainment, R&D, and intermediate goods density (per unit of labor) can enhance TFP growth. Unfortunately, there is no evidence of an overall σ convergence, indicating that TFP levels are not converging except in the South region. It implies that to catch up with leading provinces, it would require extra efforts for those lagging behind by increasing their region-specific research investment, promoting rural educational attainment, and enhancing embodied technical change. 相似文献

In social networks or, more specifically, online communities on tech-products, opinion leaders are important sources of advice for other consumers in the adoption and diffusion of new products. However, possibilities for potential users to exert their influence on opinion leadership are ignored. This study determines whether and how lead users may serve as opinion leaders in social networks and advise other consumers in the adoption and diffusion of new products. Our survey with 308 users in the Xiaomi and Huawei communities suggests that higher lead userness is positively and significantly associated with the likelihood of opinion giving and passing. Product-possessing innovativeness has a higher impact compared with information-possessing innovativeness. Product involvement does not enhance the effect of information-possessing innovativeness. The findings provide a better understanding of the formation of opinion leadership in social networks for an accelerated diffusion of new products. 相似文献

This paper aims to analyse the impact of land characteristics (i.e. altimetry and housing dispersion) on separate waste collection, with a focus on mountain municipalities. The high spatial heterogeneity of the driving factors of separate waste collection allows traditional techniques, such as OLS, to offer only a partial depiction of the situation, missing important information. In this view, we perform the Geographically Weighted Regression (GWR), which allows to control for the local determinants of waste management. Our data cover 550 municipalities of Campania, in Southern Italy. We control for a set of morphological and socio-economic variables, drawn from official records for 2012. Our results show that the relationships between land characteristics and separate waste collection are not constant over space. Moreover, they suggest that in the presence of non-modifiable factors (such as land characteristics) local governments should act on citizen motivations, promoting awareness on environmental issues, and should implement time-saving collection methods. 相似文献

This paper aims to estimate the effect of the security of farmland property rights on land-attached and long-term investment. Based on the data from a nationally representative sample with 5887 plots of 1175 households among 5 provinces in rural China, we adopt Probit, Ordinary Least Squares / Tobit, and the household fixed effect methods to yield the consistent results. The results show that the security of farmland property rights have significant and positive effects on the possibility and amount of the overall farmland investment. However, it has different effects on the different types of investments. The share of farmland retained significantly affects the investments in soil quality improvement and changing use of the plots but does not affect the investment in water conservancy facilities. The types of farmland property rights affect investments in water conservancy facilities and changing use of plots, but do not affect investment in soil quality improvement. The findings imply that the Chinese government should be the principal investor in water conservancy facilities and enlarge the operational scale of farmland by facilitating farmland transfer to increase private investment. 相似文献

Numerous countries and regions face soil fertility decline and heavy metal pollution, and China implements a policy of remediation during fallow (PRF) to deal with such challenges. In this study, we examine the evolution of PRF and surveys of farmers’ attitudes in China. We present suggestions which can be used as reference for other countries and regions. The Chinese government implemented the policy of remediation during production (PRP) to control the heavy metal pollution of land in 2014. The effect was unsatisfactory due to the lack of cooperation amongst farmers. Therefore, the Chinese government implemented PRF in 2016. Our investigation of 247 farmers shows that farmers’ comprehensive assessment of PRF is positively influenced by the cognition of government implementation, the cognition of policy function and the evaluation of value perception, and the PRF still faces several problems, such as low cognitive level of policy function, incomplete regulations of supervision and poor supporting system. Hence, we suggest that government should educate and train farmers, improve the supervision and set up the supporting system of PRF. 相似文献

优化城市基础设施对于提升居民消费水平具有积极意义。交通与通讯两类基础设施对居民线上、线下消费的影响存在差异。在普及网购的同时改善城市居民出行条件,使实体店在展示产品、现场体验等方面与电商形成互补,将有助于实现线上、线下渠道的积极互动。以2011—2016年全国近300个地级市构建的面板数据进行计量分析,验证了基础设施对居民消费的促进作用,并发现当前交通、通讯两类设施的交互作用主要体现为协同效应。进一步的研究表明,以完善基础设施支持线上、线下渠道共同发展,还能够适应居民家庭年龄结构变化的新特点。上述结论说明,以完善基础设施促成渠道协同,将对全面优化消费者体验、提升居民消费水平产生重要作用。 相似文献

In retailing, ongoing management is needed to avoid compromising customer relationships and organizational performance because of consumers' or employees' dysfunctional behavior. This paper contributes to understanding how care management strategies can improve in-store experiences for customers and employees by adapting the Chronic Care Management (CCM) theory to retailing. Across two studies, one on customers (Study 1) and one on retail employees (Study 2) we show that empowerment reduces dysfunctional behavior, enhancing satisfaction. Furthermore, we demonstrate that customers' and employees’ emotional bond with the retailer (i.e., store attachment) moderates the relationship between dysfunctional behavior and satisfaction, buffering dissatisfaction from dysfunctional behavior. 相似文献

本文以既有研究为基础,考察了企业数字化转型如何改变多元化经营的绩效影响。文章采用2007—2020年中国A股上市公司数据,运用面板二值选择模型、模糊双重差分模型以及面板固定效应模型进行实证检验,同时使用传统多期双重差分模型进行对照。研究结果表明:数字化转型与多元化经营之间具有强大的协同作用。从事实上看,数字化转型能够提高企业开展多元化经营的概率,也能够提升企业多元化经营水平。从机理上看,数字化转型能够提升企业多元化经营的预期收益,并且这一效果在劳动密集型产业中最为明显。本研究综合运用资产专用性、范围经济等理论探究了数字化转型与多元化经营之间的联动效果,开创了对于多元化经营对企业绩效影响的新型研究视角。 相似文献

This paper investigates the dynamic dependence and risk spillover between BRICS stock returns and different types of oil shocks, combining the Structural VAR model and time-varying copula-GARCH-based CoVaR approach. Our findings indicate that the dependence between BRICS stock returns and oil shocks is time-varying and exhibits different behaviours depending on the shock types in the oil market. In general, the shape of the CoVaRs in each country is comparatively different, depending on its special market situation and domestic policies. There is significant risk spillover from oil-specific demand shock to stock returns in all the BRICS countries. Finally, in Brazil, Russia and India, there is a significant asymmetric effect between upside and downside risk spillover based on oil aggregate demand shock and oil-specific demand shock. 相似文献
