我国现代农业发展的现状、问题与对策研究

近年来,在科技支撑和制度支持的背景下,我国的现代农业得到了长足发展,取得了举世瞩目的成绩。但是在发展过程中也出现了很多问题,例如:与发达国家相比,科技装备相对落后,现代农业人才严重短缺,金融支持力度不足,市场机制不完善等,因此深入研究现代农业具有重要的现实意义。文章首先对何为现代农业进行了详细阐述;然后分析了我国现代农业发展的现状;再次分析了我国现代农业发展中存在的主要问题;最后提出了切实可行的对策,为现代农业发展提供一些参考,促进现代农业科学发展。     

我国闲置土地处置中的政府功能与政策选择分析

目前我国土地闲置现象触目惊心,造成实质的资源浪费和损失。从性质上来分析,土地闲置也属于土地市场失灵,需要由行使公共职能的政府给予矫正。在目前的各种矫正措施中,有偿收回是一种较为可行的措施。有偿收回,既可提高闲置土地的处置效率,使土地效益尽早实现,又能降低博弈和交易成本,有利于维护当地的投资环境、更有利于稳定土地需求预期、端正投资动机,对地方的财政收入及经济社会平稳健康发展都具有正面价值。     

Personal Income Tax Reform in China in 2018 and Its Impact on Income Distribution

In the context of personal income tax (PIT) reform in China in 2018, this paper examines some of the major issues of concern regarding the reform and income distribution. Using the China Personal Income Tax Micro‐simulation model, the paper compares the differences between the 2011 and 2018 PIT systems, and finds that residents relying on different income sources may face a large degree of real tax rate change. Once the tax system is altered to PIT 2018, the coverage of PIT for wage earners will decrease from 46.9 to 23.4 percent, the income redistributive effect will drop from 1.95 to 1.22 percent and the PIT's role in fiscal revenue will also be negatively affected. Nevertheless, if individual income continues to grow, the share of PIT in fiscal revenue is expected to return to the 2018 level in 2022, but its income redistribution function is difficult to recover in the short term. The paper finds that the effect of PIT on income distribution depends on the tax structure. Gradual transition to an “entirely comprehensive” tax system when conditions are appropriate will achieve better income redistribution results at a lower average tax rate.     

Covariance breakdowns and connectedness of crude oil futures markets with non-synchronous data

ABSTRACT

This article identifies the breakdowns in the covariance of three benchmark crude oil futures markets (WTI, Brent and Dubai) and investigates the changes of market connectedness across the breakdown periods. As the crude oil futures are traded in different regions, this article eliminates the non-synchronous trading data by employing the Vector Moving Average structure and the Bayesian data augmentation approach, which keeps the integrity of original data without changing its properties. The results show that there are significant breaks in the covariance structure of crude oil futures markets. The breakdown periods are consistent with the periods when the market volatilities are at high level and the returns are volatile. The changes of market connectedness are independent of the covariance states, which supports the globalization hypothesis for the crude oil market. The results also suggest that there is more information flow out of the WTI than to the WTI during the sample period, particularly during the breakdown periods in 2008–2009.
