对外开放与对内开放的协同机制研究——以党的十八大以来区域协调发展战略为例

协调好对外开放和对内开放的关系,是贯彻新发展理念、建设现代化经济体系的题中之义。对外开放与对内开放的协同机制,是从区域空间布局和区域产业结构两个层面展开的。文章梳理了党的十八大以来实施的区域协调发展战略,结合以“一带一路”倡议为引领的对外开放战略,对产业全球化资源配置活动进行了分析,把区域空间布局调整与产业结构跨国调整贯通起来,刻画了对外开放与对内开放协同的内在机理。从区域协同机制来看,要建设基础条件好的开发区、自贸区、经济带,作为对外开放和对内开放协同发展的重要载体,东、中、西部地区应配合对外开放的整体布局有意识地进行梯度开放。从产业协同机制来看,对于不同类型的产业应分别采取资源占优型协同合作机制、成本占优型协同合作机制、要素融合型协同合作机制、创新引领型协同合作机制。     

农村脱贫人口返贫的阻断机制研究

随着我国扶贫的伟大胜利,返贫问题成为新的关注点。针对返贫现象形成的原因、阻断机制和对应建议,论文采用观察和深度访谈的方法对湖南一些扶贫地区展开了调查研究。研究发现,造成返贫的原因主要有四个方面:自然环境、重大疾病、文化程度和思想桎梏。论文提出其阻断机制为:建立灾害预警和应急系统、建立针对性的健康库、组织乡村培训和展开科普教育。论文对国家、地方政府和农村脱贫后的发展提出了一些建议。     

Does the social security fund help non-financial enterprises to transform from the virtual to the real?

At its 19th National Congress, the Communist Party of China vowed to “strengthen the financial sector’s ability to serve the real economy.” However, many studies provide evidence of the opposite trend, a problematic “transition from the real to the virtual,” among Chinese enterprises. Meanwhile, the investment efficiency of China’s Social Security Fund (SSF), a public fund, attracts much attention. In this context, we use A-share listed companies in China from 2009 to 2018 to study the relationship between holding by the SSF and enterprise financialization. We find that SSF holding significantly inhibits financialization and that this effect is non-linear. Mechanism analysis indicates that SSF holding suppresses enterprises’ financialization mainly by improving their governance. Moreover, SSF holding more strongly inhibits small-scale (vs. large-scale), state-owned (vs. non-state-owned), and non-eastern (vs. eastern) enterprises in China. Furthermore, SSF holding can alleviate corporate value impairment caused by financialization. The conclusions enrich theoretical research and provide empirical evidence that may help regulatory authorities to guide investment by enterprises and prevent financial risks.     

Do we really care about Biodiversity?

This paper addresses from an economic perspective the issue of global biodiversity conservation. It challenges the perception that the world really cares a great deal about biodiversity and is prepared to pay the full cost of maintaining this stock of natural capital. Despite the existence of a plethora of international agreements there still seems to be a global ‘deficit of care’ surrounding efforts to combat challenges such as those posed by global warming and biodiversity conservation. More light can be thrown on the degree of care by measuring both the actual expenditures and the stated willingness to pay for biodiversity conservation. However, actual expenditures are much lower than willingness to pay estimates recorded in the published literature. Using the criteria that the ‘right’ amount of conservation effort is one where the marginal economic benefits from conservation just equal the marginal costs of conservation, the paper explores the biodiversity conservation conundrum and concluded that, on the available evidence, the world does not care too much about this natural capital stock and bequests to future generations.

Investment-specific shocks and external balances in a small open economy model

Abstract.  We set up a standard small open economy business cycle model driven by government spending shocks, neutral productivity (TFP) shocks, and investment-specific shocks. The model is calibrated to quarterly Canadian data and its predicted moments and sample paths are compared with their Canadian counterparts. We find that the model captures the dynamics in investment and in the trade balance better than special cases of the model where either one of the productivity shocks is omitted. More specifically, the model matches the variance of the trade balance-output ratio, its correlation with output and its autocorrelation. It also matches the output-investment correlation.     

Production, trade, prices, exchange rates and equilibration in large experimental economies

We study market equilibration in laboratory economies that are larger and more complex than any that have been studied experimentally to date. Complexity is derived from the fact that the economies are “international” in economic structure with multiple input, output, and foreign exchange markets in operation. The economies have twenty-one markets and due to the fact that they have roughly fifty agents, the economies are characterized by several hundred equations. In spite of the complexity and interdependence of the economy, the results demonstrate the substantial power of the general equilibrium model of perfect competition to predict the direction of movement of market-level variables. Empirical patterns in the convergence process are explored and described.     

Intra-industry trade with multinational firms

Recent developments, including the analysis of firm-level adjustment to falling trade costs, have contributed to a revival of interest in intra-industry trade (IIT). Most empirical work still relies on the standard Grubel-Lloyd measure. This however refers only to international trade, disregarding income flows stimulated by repatriated profits of multinational firms. Given the overwhelming importance of the latter, this is a major shortcoming. This paper provides a guide to measurement and estimation of the determinants of bilateral IIT shares from the perspective of new trade theory with multinational firms. We develop an analytically solvable general equilibrium model to investigate the impact of investment costs, multinational activities and income flows from repatriated profits. We also discuss and quantify the bias of the Grubel-Lloyd index associated with repatriated profit flows of multinationals. Using bias-corrected versions of the Grubel-Lloyd index as the dependent variable, we demonstrate that the determinants motivated by our theoretical analysis offer important insights into variations in IIT shares.     

The effect of a currency union on trade: Lessons from the Irish experience

This paper studies the introduction of an exchange rate between Ireland and the UK in 1979 to shed light on the effects of a common currency on the composition of international trade. No evidence is found from time series or panel regressions that the change of exchange rate regime had a significant effect on Anglo-Irish trade. This finding is consistent with previous studies of currency unions between larger, developed countries but conflicts with findings based on more heterogeneous country groupings. The reasons for this discrepancy are discussed.
