Numerous studies have shown that agglomeration externalities play a crucial role in the survival prospects of logistics firms. However, previous studies have largely ignored the role that agglomeration externalities play at a more granular level. Therefore, this paper used Chengdu International Railway Port as a case study, constructed a distance-based agglomeration measure to explore the impact of agglomeration externalities on the survival of logistics firms located within a publicly developed logistics park (PDLP). The results show that the three types of agglomeration externalities coexist and are highly localized in the PDLP, and their effects change with distance from the logistics firm. Specifically, the specialization externalities operate within 1.5 km of the logistics firm and produce competitive effects within immediate proximity (0.5 km). Second, while diversification externalities cause significant congestion effects, interindustry knowledge spillovers arising from related diversification externalities play a key role in the 0.5 km proximity of logistics firms, and unrelated diversification externalities play a positive role in reducing the market transaction costs of logistics firms outside the 0.5 km range.
As China's economy advances toward high-quality development, how to promote the rational spatial distribution of skilled labor to achieve sustainable regional economic growth has become an urgent issue. This study utilizes microdata from the 2000–2015 Chinese census and tariff data from China covering the same period to empirically regress input tariff cuts on changes in the proportion of skilled labor in cities. The results show that for every 1% decrease in input tariffs, the proportion of skilled labor in cities increases by 0.78%, accounting for 15.22% of the spatial distribution of skilled labor. Mechanism analysis indicates that input tariff cuts facilitate technological progress and subsequently increase skilled labor demand. From an equilibrium perspective, increased skilled labor demand attracts skilled worker inflows, thereby increasing the proportion of skilled labor in cities. Additionally, input tariff cuts have a more significant impact on cities with low trade costs, a high historical proportion of skilled labor, and high labor market flexibility. These findings provide favorable evidence of the micro-level impact of input tariff cuts on regional skilled labor markets, offering important policy insights into how developing countries similar to China can optimize the spatial distribution of skilled labor through input tariffs.
Despite increases in school enrolment, the world is facing a global learning crisis that suggests a trade-off between the quantity and quality of education.
This case study from Ghana examines whether there has been a long-term change in educational outcomes, measured by population literacy and numeracy rates, in the decades following the implementation of a national free compulsory basic education policy. It further determines whether there are variations by level of education in the changes over time.
This study used nationally representative repeated cross-sectional data from two Ghana Living Standards Surveys (2006 and 2017) to estimate basic literacy and numeracy.
At the same level of education for the primary and lower secondary school levels, literacy and numeracy were lower in the latter period than a decade previously. These findings suggest that the expansion in gross enrolment at the primary and lower secondary school levels has been associated with a long-term decline in the quality of education.
Considering these findings, it is crucial to consider the long-term implications of expanding access to education on the quality of the education provided. These findings highlight the need for increased investment in quality education to complement the increase in access. This would ensure that children acquire foundational skills at the basic education level. Failure to maintain quality alongside expanded access could negatively impact workforce productivity, economic growth, and social equality.
