基于TAM的农户环境友好型技术采纳意愿的影响分析——以测土配方施肥技术为例

[目的]以测土配方施肥技术为例,侧重于农户心理机制分析农户对环境友好型技术采纳意愿的影响因素,以期为促进环境友好型技术推广的政策制定提供参考。[方法]文章基于技术接受模型理论,运用江西省8县554户农户调查数据,借助结构方程模型对农户环境友好型农业技术采纳意愿的影响因素进行实证分析。[结果]效果展示对农户采纳意愿影响最为显著,且通过感知有用性和感知易用性对农户意愿产生正向影响;感知易用性和感知有用性是影响农户意愿的重要因素,且感知易用性对感知有用性能够产生正向影响;社会影响对农户采纳意愿和感知易用性有显著正向影响,但对感知有用性的影响作用不显著;采纳条件对农户感知有用性、易用性都没有显著性的影响,但对采纳意愿具有显著的负向影响作用。[结论]重视技术的效果展示,提升农户对环境友好型技术成效的认可程度;开发简捷易行的使用方法并加大宣传力度,提升农户对环境友好型技术的易用性和有用性感知;改善技术采纳条件,创新技术推广机制。     

Spatial Modeling in Technology Adoption Decisions: The Case of Shuttle Train Elevators

This article empirically models a strategic game of technology adoption of shuttle train grain elevators with information on location of the firm and its competitors. A spatial econometric model illustrates the role of spatial interdependence of rivals' decisions as well as agronomic and competitive variables on discrete adoption decisions. The analysis assesses equilibria conditions that characterize technology adoption, in this case of shuttle train adoption, and the results provide an explanation of shuttle train adoption decisions in the grain handling industry in which spatial competition is critical.     

Industrial Policy and Technology Diffusion: Evidence from Paper Making Machinery in Indonesia

In this paper, we analyze the diffusion and adoption of paper making machinery in the Indonesian pulp and paper industry, from 1923 till 2000. We develop a machine level index of technological sophistication (mach), which measures the technological distance of each paper machine to the world technological frontier. The data reveal a pattern of rapid technological catch up. But catch up was not an industrywide phenomenon. Some modern firms installed state-of-the-art machinery, while others installed older vintages. The paper argues that industrial policy has played an important role in the speed and nature of diffusion of paper making machinery.     

Social learning and technology adoption: the case of coffee pruning in Peru

A unique natural experiment involving a coffee pruning technology is used to study social learning. The yield effects of pruning take two years to appear, a characteristic that aids in identifying social learning apart from correlated unobservable variables that are a concern in the social learning and technology adoption literature. Panel data are employed that start with a private initiative which introduced systematic pruning in central Peru and that contain the population of participating growers. Results show a jump of at least 0.15 in the probability of adoption two years after the first pruning in a grower's group.     

农业用水非农化对农户粮食生产用水行为的影响基于山东省728份农户调查数据

目的 农户作为微观经营主体,其节水技术的采用将提高粮食生产用水效率,达到节约水资源与保证粮食生产的双重目的。通过分析农户粮食生产用水行为,探讨水资源短缺约束对农户粮食生产技术采用的诱致效应。方法 文章基于2019年对山东省728份农户的调查问卷数据,以农户行为理论为基础,综合运用统计分析、Logit模型等方法,对农业用水非农化约束下农户的粮食生产用水行为进行分析。结果 在农业用水非农化态势下,作为理性经济人的农户倾向于采用节水技术,以保证粮食生产。农户年龄、家庭农业劳动力人数、灌溉水源与灌溉方式对其节水技术的采用影响显著为负,农业年收入、小麦及玉米种植面积对农户节水技术的采纳行为影响显著为正。结论 规模化经营是大型节水设施应用的基本条件,应当加快农地流转,推进粮食生产规模化经营,提高粮食灌溉的规模化和标准化水平;同时加快建立科学合理的农业水价改革制度,促进农民节约农业用水,以此实现水资源利用效率提高与粮食生产能力稳定的双重目标。     

The Internet of Things (IoT) in retail: Bridging supply and demand

A sales channel serves two primary functions: delivering information and products to customers. Omnichannel retailing allows for the decoupling of these two functions as consumers can learn about products through channels that differ from those used to purchase them. This separation requires a sophisticated inventory and supply chain operation, as well as integration of all customer touchpoints, in order to match fast-moving supply and demand. The Internet of Things (IoT) can play a fundamental role in channel integration because it allows companies to rebalance supply and demand. We classify IoT initiatives on an opportunity map, presenting a strategic framework that distinguishes initiatives by the value they create and by their major area of impact. We justify the adoption of IoT in terms of its enabling capabilities—those immediately realized by deploying IoT sensor data—but its true potential resides in its enhancing capabilities—unanticipated benefits following IoT adoption—at the intersection of supply and demand.     

IFRS adoption and stock misvaluation: Implication to Korea discount

Analyzing publicly traded stocks in Korea surrounding IFRS adoption in 2011, we find that the gap between stock price and firm value, value-to-price (V/P) ratio, narrows following the IFRS adoption and that this narrowed gap is observed only for higher V/P firms. We further find that the return predictability of V/P decreases in the post-IFRS period. Using a path analysis, we report further evidence that mandatory IFRS adoption decreases idiosyncratic volatility and improves trading volume and market liquidity, thereby contributing to the narrowed gap between value and price. We conclude that IFRS adoption contributes to resolution of Korea discount.     

Interaction between crop insurance and technology adoption decisions: The case of wheat farmers in Chile

This paper examines relationships between crop insurance and input technology decisions among Chilean wheat farmers. Using nationwide farm‐level data, a bivariate probit model is estimated. We investigate the extent to which the adoption of production input technologies is associated with farmers’ participation in the insurance program. We find that relationships between insurance and technology decisions are significant only for family farmers. In particular, there is a negative relationship between participation in the insurance program and the adoption of modern irrigation. Interpretations based on the role of input technologies on insurance adoption and adverse selection behaviours are discussed.
