东南地区稻农新品种技术采纳行为影响因素及技术发展、推广策略——基于福建省水稻种植户的调查

在梳理相关领域研究成果的基础上全面择取研究指标,以福建省种稻农户为调查对象,通过随机抽样调查获取相关数据,探究新形势下影响我国东南地区稻农新品种技术采纳行为的主要因素。构建模型,通过单因素分析叠加多因素分析,测算出土地类型、种稻的最主要动机、水稻性状偏好、周围稻农更新频率、农技推广人员影响程度是东南地区稻农新品种技术采纳的显著影响因素。进一步研究发现,适合山垄田品种、优质品种的更新需求存在缺口,种稻农户的品种更新行为仍然受到周围稻农的极大影响,农技推广人员起到重要的正面作用。基于研究结论,有针对性地提出确立以优质稻品种选育为重点的良种技术发展方向、良种技术发展应关注小众农户的特殊需求、扩大良种技术示范户的影响覆盖面、持续推进接触式农技推广工作方式几点建议。     

Technology addiction,abduction and adoption in higher education: Bird's eye view of the ICT4AD policy in Ghana 20 years on

Twenty years after its inauguration, the information communication and technology for accelerated development (ICT4AD) policy intended to transform Ghana into an information and technology-driven high-income economy through digital education has been unsuccessful. In this digital era, young adults' attachment to technological tools is anticipated to expedite technological adoption in the education sector. Still, there are less promising indicators of realizing this expectation because of situational factors that curtail technology usage and adoption in higher education (HE). It is estimated that the adoption of technology in HE will aid Ghana in using ICT as its engine of growth. This paper gauges the progress of the ICT4AD policy after two decades, presents an intricate account of why technology integration in HE in Ghana is still in its infancy and proposes interventions for sustaining and advancing the objectives of the ICT4AD policy. Drawing from an extensive review of literature on three conceptualized thematic themes relating to technology (ie, addiction, abduction and adoption), policymakers in education and stakeholders in HE will be able to identify their roles in guaranteeing the success of the promulgated ICT4AD policy. Viable areas of research are also discussed in the study.

Practitioner notes

What is already known about this topic?

• The promulgated information communication and technology for accelerated development (ICT4AD) policy of Ghana hopes to transform the country into a technology-driven economy.
• Technology integration in education and society is still in its infancy in Ghana in this information age.

What this paper adds?

• It gauges the progress of the ICT4AD policy and presents an intricate account of why technology integration in HE in Ghana is still in its infancy and proposes interventions for sustaining and advancing the objectives of the ICT4AD policy.
• It sounds the alarm that the ICT4AD policy is at its terminal stage and calls on policymakers in education to revisit and revise the policy.
• It identifies the main factors curtailing effective technology integration in Ghana.
• It suggests promising steps for Ghana to adopt technology as its engine of growth.

Implications of this study for practice and/or policy

• It provides information to education practitioners and relevant school stakeholders on how to effectively adopt technology to develop 21st-century skills among learners.
• It explores the potential channels for policymakers in education to revisit and reinvest in the ICT4AD policy for the successful attainment of the policy objectives.
• It calls on countries with similar contexts like Ghana to adopt a multifaceted approach to drive ICT initiatives.

     

农产品供应链区块链技术采纳决策研究

基于区块链采用成本的考虑，构建电商平台主导、农企跟随的两阶段博弈模型，通过对比区块链技术应用前后批发价、零售价等决策变量以及农企和电商平台的利润变化，探究采纳区块链技术对批发价、零售价的影响，并找到在采用区块链技术情况下电商平台和农企均受益的路径。研究表明，电商平台采纳区块链技术会导致农企提升批发价，产品零售价也随之增加，同时产品需求量也增大；然而，采纳区块链技术的电商平台和农企却并不一定能实现双赢，只有满足农企学习效率为高水平或农企学习效率和电商平台的追溯效率均为低水平时，采纳区块链技术可使农企和电商平台共同受益；反之，采纳区块链技术只能使电商平台受益。因此，农企应根据自身学习效率的高低理智地作出相应决策。     

企业与消费者对颠覆性技术采纳行为的动态演化及影响因素： 基于演化博弈视角

关注企业与消费者对颠覆性技术采纳行为在颠覆性技术实现颠覆过程中发挥的作用以及相关影响因素，从而为企业应对颠覆性技术时的决策提供参考。以参与方有限理性和信息不完全为前提，构建企业与消费者对颠覆性技术采纳行为的演化博弈模型，分析两者采纳颠覆性技术与否的稳定策略，并借助MATLAB进行数值模拟仿真，分析验证该模型具体的演化路径，从而探究两者在颠覆性技术采纳行为博弈过程中决定双方最终策略选择的影响因素。结果表明：（1）企业与消费者对颠覆性技术的初始态度将对两者采纳颠覆性技术的行为产生影响；（2）颠覆性技术产品为企业与消费者带来的收益大小、企业选择采纳颠覆性技术所需投入的成本大小、企业选择不采纳颠覆性技术所需支付的机会成本大小、消费者选择采纳颠覆性技术产品所需支付的成本大小等因素，均会对企业和消费者在颠覆性技术采纳行为上的最终策略选择存在较为显著的影响。因此建议企业建立健全颠覆性技术常态化管理机制与跟踪机制，优化在颠覆性技术采纳行为过程中的成本投入和成果转化水平，以充分实现颠覆性技术的战略价值。
