近年来,“三农”问题受到极大关注。为了应对外部资源、环境、科学技术等多重压力对农业升级与发展的影响,政府出台了诸多政策支持农业企业的技术研发与创新。本文从政府干预视角分析政府补助和税费返还两种形式的政府创新支持政策对农业企业研发投入的影响,重点分析机构投资者与大股东参与公司内部治理以及社会审计事务机构参与公司外部治理这两者所发挥的不同监督作用。研究发现:第一,不同形式的政府创新支持(政府补助和税费返还)对农业企业研发投入的影响并不一致。政府补助产生替代效应,税费返还则产生互补效应。第二,持股监督(机构投资者和大股东的持股比例上升)能增强政府补助对农业企业研发投入的替代效应,也能增强税费返还对农业企业研发投入的互补效应。第三,审计监督(社会审计事务机构的审计意见)会减弱政府补助支持对农业企业研发投入的替代效应,也会减弱税费返还对农业企业研发投入的互补效应。本文的研究发现为政府制定适宜的创新支持政策,以及合理发挥持股监督与审计监督的内外部治理作用,提供一定的决策依据和理论支持。 相似文献

This article investigates how uncertainty impacts the effect of monetary policy surprises on stock returns. Using high-frequency US data, we demonstrate that stock markets respond more aggressively to monetary policy surprises during periods of high uncertainty. We also show that uncertainty asymmetrically influences the transmission of positive and negative monetary policy surprises to stock market prices. The amplifying effect of uncertainty is found to be stronger for expansionary shocks than for contractionary shocks. Our robustness analysis confirms that financial uncertainty has a significant role in shaping the influence of monetary policy on the stock market. 相似文献

The COVID-19 pandemic has had a great impact on food shopping behavior. However, changes in food shopping behavior and related decision-making mechanisms remain unexplored. This study conducted a face-to-face questionnaire survey with 900 residents in three communities in Haidian, Beijing, China, to analyze food shopping behavior during the periods of pre-lockdown, lockdown (January–March 2020), and post-lockdown. Our results indicated that the preference for fresh food e-commerce shopping was accelerated by the lockdown with the usage rate increasing by 48%; the wet markets were seriously hit by the lockdown policy and had not fully recovered by the post-lockdown period (with a 75% reduction in the usage rate during lockdown). The psychological mechanisms of changes in food shopping behavior revealed that the context (e.g., community facilities) and the perceived risk of COVID-19 were two significant factors impacting the four shopping choices investigated. Specifically, the context factors affected behavior directly for supermarkets and convenience stores and indirectly for e-commerce and wet markets. The findings are expected to help in guiding emergency responses during a future pandemic as well as the long-term construction of food supply facilities. 相似文献

在供给侧改革背景下,科技保险肩负着为科技创新保驾护航的历史使命。然而,科技保险试点10年来,依然面临需求低迷与供给不足并存的发展困境。其主要根源在于:严重的信息不对称造成市场失灵、“跛行”的财政支持政策不能形成有效激励以及不成熟的行业环境制约。要想走出这一困境,仅仅从需求方着力是远远不够的。科技保险的正外部性和科技保险市场高度的信息不对称,决定了必须从财政支持、产品创新、机制创新、中介培育及信息服务等方面进行供给侧改革。为此,提出应当构建供需并重的差异化财政支持机制、加大与需求侧相匹配的科技保险产品供给、创新科技保险契约模式及运行机制、搭建科技保险中介服务和信息支持平台等建议。 相似文献

This paper critiques the emergence of Dangote Cement as the dominant player in cement manufacturing in Nigeria. It argues that the changed economic environment General Obasanjo met when he became president of Nigeria for a second time in 1999 made it difficult for him to continue the nationalisation policies and the expansion of government involvement in several spheres of economic activity that he helped to promote in the 1970s. The realisation that this strategy, which created numerous crony capitalists, was unsustainable resulted in Obasanjo allying with Dangote and promulgating the Backward Integration Programme (BIP) for the local cement industry. This made it possible for Dangote to risk aggressive investment in the capital-intensive cement production business. This strategy achieved public good by rapidly making Nigeria, an oil rent- and import-dependent economy with enormous limestone reserves, self-sufficient in cement production. 相似文献

[目的]为了解决甘肃中部安定区、陇西县、渭源县、临洮县、榆中县和会宁县的人畜饮水、工业用水、生态用水及农业灌溉用水问题,引洮工程通过九甸峡水利枢纽抬高水位将黄河上游洮河支流水资源引入受水区。在受水区,在调水增加本区供水总量的同时,相应增加了增量水资源使用后带来的废污水,客观上对污染治理工作水平提出了更高要求,轻视排污问题将加剧受水区乃至下游的水系污染程度,影响受水区经济社会的可持续发展。[方法]文章采用文献研究法从理论上探讨了环境容量、排污权及其关系。采用定额计量法计算了调水带来的COD和氨氮增量。[结果]调水使得受水区COD和氨氮每年分别增加6 914. 30t和1 440. 48t。就COD而言,受水区平均排放量占该区环境容量的51. 12%,似有较多的容量结余,但区内排放极不平衡,榆中和会宁已经超排。就氨氮而言,受水区平均排放量将占该区环境容量的151. 55%,总体超排很严重。区内除临洮以外,其余5县区均超排,其中,榆中和会宁超排1倍以上。[结论]排污量是假定增量污水符合二级排放标准的前提下计算的,如果处理率低、排放达标率低,则超排现象会更为严重。对此,要从宏观上进行综合治理,诸如完善政府、社会与市场共同治污机制、排污权配置的过渡性制度安排、污水处理企业改革及引导受水区进行产业结构调整等。 相似文献

The prevailing transitions literature suggests that dynamic firms in postsocialist economies are the result of macroinstitutional reforms leading to the making of markets. This article builds on work in comparative political economy and economic sociology to show that the degree of competitive behaviour of postsocialist firms is determined not by the existence of general market institutions alone but by the kinds of organisational allies firms possess and the kinds of markets they compete in. Using firm survey data across 28 postsocialist economies, the article examines the determinants of competitive restructuring by firms, including product innovation, standards upgrade, financial transparency, and investments in research and development. The article confirms insights from comparative political economy which suggest that dynamic enterprise sectors emerge when governance is effective. However, at the firm level, the article finds that transnational ties and supportive policy environments are most significant in the making of dynamic postsocialist enterprises. The article also highlights important regional variation in firm behaviour and discusses the relationship between institutional frameworks, organisational embeddedness, and firm restructuring in postsocialist economies. 相似文献

Instructional Manipulation Checks (IMCs) assess respondent behavior by, for example, asking participants not to answer a trick question. We find IMCs can be used to detect problematic response behavior in longitudinal surveys. This is important because a Latent Class Analysis based on IMC-failure in the two reported studies reveals that between 9% and 12% of respondents can be labelled Inattentive Stayers at the first survey-wave and between 13% and 17% at the third wave. The tendency of Inattentive Stayers to remain in the panel is particularly relevant for online panel services such as MTurk, with workers participating in many surveys over longer time-periods. We find IMC-failure to be mitigated by a warning to respondents that their attention will be checked early in the survey, but not by repeated exposure to IMCs, or a timer leaving questions on the screen longer. Respondent personality also plays a role in IMC-failure, which implies persistency of undesirable respondent behavior. 相似文献

This article analyzes the career and contributions of Roy Blough (1901–2000) as a case study of Wisconsin institutionalism in government policy-making at midcentury. As a faculty member at Cincinnati, Chicago and Columbia, editor of the National Tax Journal, director of the research division of the U.S. Treasury and member of the Council of Economic Advisors, Blough played a significant role in the development of fiscal policy. The article also considers Blough’s contributions to tax policy and his views on Keynesian public finance. It further identifies the contributions of Wisconsin institutionalism to modern fiscal policy. 相似文献

Institutional Economics as Theory of Policy Change: Impact of Past Policy Failures on Present Policy
Koji Noda 《Journal of economic issues》2018,52(1):117-135
Social scientists have developed several theories for understanding or evaluating policy change over time. Since all costs or benefits are not internalized owing to positive transaction costs, policymaking is always implemented under cost underestimation conditions and, therefore, is imperfect. I call this trait policy failure in this article. Furthermore, I show that a new framework combining the social costs approach and the legal/economic approach in institutional economics is suitable and can be applied to evaluating how past policy failures affect present policy, providing as an example the Fukushima nuclear disaster in Japan. 相似文献
