Migration,self‐selection and income distributions

Self‐selection in rural–urban migration is examined using three datasets from rural and urban China in 2002. We construct a migrant sample including both migrants who converted their hukou status from rural to urban (permanent migrants) and those who did not (temporary migrants). We find a strong positive selection for permanent migrants, but the selection for temporary migrants is ambiguous. We reach these conclusions by comparing migrants' counterfactual wage densities, assuming they are paid as rural local workers, to actual wage densities of rural local workers. Our results imply that permanent migration has negative effects on rural human capital accumulation and income levels.     

我国农村产业融合发展研究

[目的]农村产业融合发展是打造新农业农村经济增长极的重要载体,是构建蓝绿交织、清新明亮、产业共融的田园综合体的有效途径,对于促进农民增收、农业增效、农村增绿具有重要意义。[方法]文章根据统计数据,通过定性分析的方法,对我国农村产业融合发展意义、现状、机遇及制约因素进行了深入研究。[结果]当前我国农村产业融合发展初见成效,发展模式日益多样化、经营主体逐步多元化、利益联结机制不断健全。新形势下,我国农村产业融合发展的制度环境更加优越、物质基础更加雄厚、市场空间更加广阔、内生动力更加强劲。但是,我国农村产业融合还处于起步阶段,农村产业融合层次浅、新型农业经营主体带动能力弱、利益联结机制松散、要素瓶颈制约尚未打破、基础设施建设滞后等问题比较突出。[结论]提出应从加强顶层设计、完善产业融合模式、强化新型农业经营主体的带动能力、健全利益联结机制、激发多种要素、加强基础设施建设等方面搭建农村产业融合发展平台,促进农村产业融合发展驶入"时代高铁"。     

产业集群治理:一个基于浙江省企业社会责任实证的视角

治理是一个比较宽泛的概念,适用于国际、国家、社区的不同领域的管理,治理的形式一般有企业治理、区域治理等。产业集群治理的提出与多重背景有关:全球化的迅猛发展、产业集群系统的复杂性和产业集群组织失灵的存在。产业集群治理包括外部治理和内部治理。外部治理主要是通过全球价值链治理来进行,而内部治理主要是网络治理。在治理结构中,企业社会责任是一个重要的约束条件。文章分析了企业社会责任与集群治理结构的关系,并以浙江产业集群为例进行了实证研究,认为从企业社会责任的视角探求产业集群治理具有重要的理论价值和实践意义。     

Venture capital,innovation, and growth: evidence from Chinese metropolitan data

Using panel data from 282 Chinese cities from 2003 to 2015, we estimate the impact of venture capital (VC) on innovation, employment, and payroll in metropolitan areas. Controlling for endogeneity, VC investments are significantly positively related to metropolitan innovation, employment, and payroll in a fixed effects panel regression and dynamic GMM estimation. Using the number of IPOs (Initial public offerings) in the city as an instrumental variable to again control for endogeneity, VC remains significant. Our results show that VC is significantly contributing to the metropolitan economy as a whole by supporting innovation, creating jobs, and generating wealth in the local cities.

The impact of credit constraints on the performance of Chinese agricultural wholesalers

This article evaluates the impact of credit constraints on the performance of Chinese agricultural wholesalers. We estimate a stochastic frontier function using transaction and credit data of agricultural wholesalers from across China to estimate the efficiency and productivity impacts of credit constraints on sales of affected agricultural wholesalers. Empirical results show that micro- and smaller wholesalers are disproportionally impacted by credit constraints and that eliminating these constraints would increase the sales of affected agricultural wholesalers by approximately 15%. Thus, policies aimed at providing credit access for these wholesalers would significantly boost the performance of smaller agricultural wholesalers while improving the overall performance of the Chinese food supply chain without requiring additional non-credit inputs.     

Effects of government spending shocks in China,Japan, and Korea

ABSTRACT

This study investigates the effects of government spending shocks on various key macro variables in China, Korea, and Japan using structural VAR models. The main empirical findings are as follows. Government spending multipliers of all three countries are far larger than 1 in recent years. The effectiveness of fiscal expansion has not changed markedly in China but substantially increased in Korea (after the Asian financial crisis) and Japan (during zero lower bound period). Increases in the effectiveness of fiscal expansion are associated with changes in the monetary and exchange rate policy regimes and institutions of these countries. Among the three countries, the government spending multiplier is relatively large in China but relatively small in Japan in recent years. Although the effects on exchange rate and trade balance vary across countries and sample periods, real exchange rate tends to depreciate, whereas trade balance tends to improve under flexible exchange rate regimes. Some empirical findings are consistent with standard theory, but others are not.

实施企业生态工程,促进循环经济的发展

继工业文明后,生态文明是一种正在生成的发展的文明范式,它是人类文明发展的又一个新的高级阶段。而实施企业生态工程,发展循环经济,是构建生态文明,实现工业与经济社会良性发展的重要途径。这要求在宏观上发展循环经济加快产业生态化,构建工业企业实施生态工程的动力机制及其政策,在微观上建设生态工业园区推进工业企业实施生态工程的实施。     

基于动力机制的我国产业集群发展研究

产业集群动力机制是获取持续竞争优势和推动我国产业集群发展的根本力量,其包含内源动力机制和外源动力机制。内源动力机制将产业集群中包含的本地根植性蕴涵丰富的要素（资源）转化为内生优势;外源动力机制分为政府行为、外部竞争环境等,其作用带来产业集群的外部优势。以产业集群动力机制及其作用规律研究为基础,产业集群内部治理与集群政策相结合的“从下到上”思路,是有利于我国产业集群发展的新模式。     

Assessing market dominance

We propose a new measure to assess market dominance. Contrary to concentration measures such as the Herfindahl–Hirschman index that characterizes the concentration of an industry, our dominance measure suggests an approach that classifies when an individual firm has a dominant position. In our measure, the criterion for dominance is relaxed as the intensity of existing competition increases or as entry barriers are lowered. We apply the dominance measure to a number of well-known competition cases.
