揭示"制度与增长关系之谜"的一个研究视角——基于中国经济转型与经济增长关系的实证研究(1978-2004)

本文通过对中国经济转型与经济增长之间的实证研究,发现经济增长是直接推动经济体制转型深化的内在动力,而经济转型虽然对经济增长有长期的影响作用,但这种作用却不是决定性的.在制度与增长二者关系中,制度虽然是影响增长的长期重要因素,但这种影响却不是决定性的;而恰恰相反,增长对制度的影响却是决定性的.这说明制度创新在增长的大背景中更易达到,而中国改革成功的经验也充分证明了这一点.

Choosing sides in the trilemma: international financial cycles and structural change in developing economies

ABSTRACT

This paper analyzes the impact of international financial cycles on structural change in developing economies. It is argued that the impact of these cycles depends on the specific combination of macroeconomic and industrial policies adopted by the developing economy. The cases of Brazil and Argentina are contrasted with those of Korea and China. In the Asian economies, macroeconomic policy has been a complementary tool along with industrial policy to foster the diversification of production and capabilities. Inversely, in the case of the Latin American countries, long periods of real exchange rate (RER) appreciation, combined with the weaknesses (or absence) of industrial policies, contributed to the loss of capabilities and lagging behind.     

绿色工艺创新扩散波动对经济增长的冲击

本文构建了一个两部门DSGE模型,同时考虑了创新扩散的一般规律(“S型扩散”)与企业绿色技术创新扩散的独特作用(节能作用和减排作用)。基于人口老龄化的预测,模拟随着企业绿色技术创新扩散的波动,经济系统所做出的响应。结果表明：经济变量对于企业绿色技术创新扩散的波动呈现出不同的响应路径,其中资本存量的响应具有滞后性；资本报酬率为首的相关经济变量对于正向冲击的响应出现了“翘尾效应”。最后,本文给出了稳定、正向引导市场预期和在资本市场采取预调机制的政策建议。     

知识型服务贸易与经济增长

在罗默、格罗斯曼和赫尔普曼知识国际流动增长模型的基础上，比较分析了在知识国际流动的情况下，没有知识型服务贸易和有知识型服务贸易的经济增长差异，指出了知识型服务贸易对消除知识和技术在国际间的重复研发，提高长期创新率和经济增长率的重要作用，并就加快我国知识型服务贸易的发展提出了政策建议。

Externalities,Cross-Sectoral Spillovers and Productivity Growth

We provide an interpretation of the productivity dynamics in the manufacturing sector based on the idea of the thick market externality à la Diamond. An econometric model has been estimated which allows to disentangle the long run effects of these trading externalities from those of internal economies of scale and of aggregate industry-level economies. The results obtained—based on a cointegrated system of non-linear-error-correction equations—confirm the hypothesis that the trading externality matters. Moreover, our findings point out that the emphasis generally posited both on internal and external economies of scale is not justified.     

Intraday Empirical Analysis and Modeling of Diversified World Stock Indices

This paper proposes an approach to the intraday analysis of diversified world stock accumulation indices. The growth optimal portfolio (GOP) is used as reference unit or benchmark in a continuous financial market model. Diversified portfolios, covering the world stock market, are constructed and shown to approximate the GOP, providing the basis for a range of financial applications. The normalized GOP is modeled as a time transformed square root process of dimension four. Its dynamics are empirically verified for several world stock indices. Furthermore, the evolution of the transformed time is modeled as the integral over a rapidly evolving mean-reverting market activity process with deterministic volatility. The empirical findings suggest a rather simple and robust model for a world stock index that reflects the historical evolution, by using only a few readily observable parameters.
