The effect of corporate real estate ownership on R&D innovation: credit relief vs. resource replacement in China

Against the background of supply-side structural reform and the real estate financialisation in China, this study investigates the impact of real estate holdings on R&D investment using data of enterprises listed on the Shanghai and Shenzhen stock exchanges. Our empirical results yield five main findings. First, enterprises holding more real estate assets face more serious financial constraints, thus restraining corporate innovation efficiency. Second, when the profit margin gap between entity enterprises and the real estate industry is larger, enterprises are more inclined to transfer industrial capital into the real estate industry, thus reducing R&D investment. Third, when the degree of marketisation is high, intensified market competition, the optimal allocation of factor and product markets, and stronger patent protection will weaken the restraining effect of corporate real estate holdings on R&D investment. Fourth, monopoly enterprises obtain potential profits more than undertaking risks from the real estate industry, they are more willing to hold real estate, thus strengthening the restraining effect of real estate holdings on innovation. Finally, investors' regional preference intensifies the restraining effect of corporate real estate holdings on R&D investment. Our empirical evidence can guide entity enterprises on how to effectively balance short-term (non-productive) and long-term (productive) capital investment.     

关系质量对企业知识创造绩效的作用机理：一个被调节的中介模型

基于嵌入性视角，分别引入知识转移、合作模式作为中介变量和调节变量，深入探究关系质量影响企业知识创造绩效的内在机理。利用277份来自全国多地的制造业及高新技术企业调查问卷，采用多元回归方法进行实证研究。结果表明：经济型和社会型关系质量均正向影响企业知识创造绩效；社会型关系质量通过元素知识和架构知识转移正向影响企业知识创造绩效。在契约治理模式下，经济型关系质量更倾向于通过元素知识转移正向影响企业知识创造绩效；在股权治理模式下，社会型关系质量更倾向于通过架构知识转移正向影响企业知识创造绩效。     

Impulse response function analysis of the impacts of land value-added tax policy on government performance

In this study, an epsilon-based network data envelopment analysis is employed to construct assessment mechanisms for government performance. Moreover, performance indicators of two dimensions of tax collection efficiency and financial effectiveness are measured. We propose a vector autoregression model in which all economic variables are regarded as dependent variables to address the disadvantages of traditional regression model. The conclusions are as follows: (a) measures of tax collection efficiency deteriorated, whereas those of financial effectiveness improved. (b) In an impulse response analysis of the model, an increase in government-published land values produced significantly increased tax collection efficiency.     

Volatility forecasting: long memory,regime switching and heteroscedasticity

In this article, we account for the first time for long memory, regime switching and the conditional time-varying volatility of volatility (heteroscedasticity) to model and forecast market volatility using the heterogeneous autoregressive model of realized volatility (HAR-RV) and its extensions. We present several interesting and notable findings. First, existing models exhibit significant nonlinearity and clustering, which provide empirical evidence on the benefit of introducing regime switching and heteroscedasticity. Second, out-of-sample results indicate that combining regime switching and heteroscedasticity can substantially improve predictive power from a statistical viewpoint. More specifically, our proposed models generally exhibit higher forecasting accuracy. Third, these results are widely consistent across a variety of robustness tests such as different forecasting windows, forecasting models, realized measures, and stock markets. Consequently, this study sheds new light on forecasting future volatility.

征占用林地生态公益林价值评估的探讨

国家重点工程建设常常需要征占用生态公益林的林地.在进行补偿时,如何评估此生态公益林林木的价值呢?不同评估方法,其评估价值有很大的差异.本文将征占用林地的天然生态公益林的评估价值定为以培育中径材为目标的同类林分用材林评估价值的三倍至五倍.作者认为这样的评估价值最接近现行市场交易价,能够为征占用单位和林木所有者所接受.     

加大关键性领域改革力度奠定经济发展体制基础

2005年,是我国改革与发展继往开来的重要年份。我国将要完成“十五”规划提出的各项主要任务,并向全面建设小康社会的第二个五年迈进;同时,加入世贸组织的三年过渡期基本结束,开始跨进范围更广、层次更深的开放型经济。2005年能否保持经济平稳较快增长,不仅关乎年度宏观经济稳定,而且涉及能否为“十一五”期间奠定坚实的、可持续的基础,甚至将影响到整个“十一五”时期的经济走势。因此,今年经济工作不仅应实现年度宏观调控的四大目标(经济增长、物价稳定、就业增加和国际收支基本平衡),而且还要为延长经济上升期创造有利条件。一、目前我国…     

票据无权代理追认制度微探

票据行为是一种法律行为，自然也可以以代理方式为之。民法上有关代理制度的规则一般也都可以适用于票据代理行为。但由于民法与商事法的立法旨趣各有侧重，为促进票据流通、保障交易安全，票据代理不能照搬民法上关于代理制度的规定。票据的无权代理是票据代理中一个非常典型的问题，与民法上的无权代理区别很大，其中存在的问题很多。对于票据的无权代理中是否应当赋予本人以追认权，多数大陆法系国家的立法例与英美法系国家之立法例有所不同。
