Empirical Analysis on the Mechanism of Industrial Park Driving Urban Expansion: A Case Study of Xining City

Taking Xining City as an example, this article analyzes the mechanism by which industrial park construction drives the expansion of urban population size and built-up area, based on a review of the process of industrial park development and urban population growth. It also discusses future urban governance models in light of urban development trends. The research finds: (1) In the process of urban development, industrial park construction is often the initial factor in the cumulative and cyclical development of a city; (2) As the level of development improves and the mode of economic growth changes, the government should timely adjust its strategies, shifting from the expansion of industrial park construction towards structural optimization and quality improvement. The most significant difference from previous research is that this paper emphasizes the importance of government planning. This study can not only demonstrate the general process of industrial parks promoting urban expansion, but more importantly, it explains the fundamental reasons for the transition of urban expansion to adjustment from a mechanism perspective, thereby eliminating the drawbacks of simply predicting urban scale evolution through data models.

On Several Issues Concerning the Moderate Codification of Education Law in China

The compilation of the education code is a key task for many countries to promote the revitalization of education, and it is also an inevitable trend of education development. Determining the path, choosing the compilation model, designing the structural framework, and technical positioning are the key issues in realizing the compilation of the education code. In terms of the path, it is recommended to adopt the "two-step" approach of drafting the general provisions first and then compiling the specific provisions. In terms of the selection of the compilation model, it is recommended to adopt the idea of "moderate compilation" to balance the characteristics of my country's existing legal system in the field of education. Under the framework of "general provisions + specific provisions", the general provisions should be structurally arranged around the right to education, and the specific provisions should be logically arranged according to the type of education. In terms of structural framework and reconstruction, a system that meets the unique system logic requirements should be considered to achieve the scientific nature of the education code. The "common element extraction method" should be selectively used to summarize and generalize legal norms.

Climate policy uncertainty and energy transition: Evidence from prefecture-level cities in China

Extreme weather has become a severe threat to humanity today, with a major blow to energy systems. Energy transformation has become a significant trend in global development, and China has the responsibility and obligation to combat climate change. This paper examines the impact of climate policy uncertainty on energy transformation in China at prefecture-level cities level. A new climate policy uncertainty index and a new measure of energy transition are proposed. The results indicate that climate policy uncertainty has a negative impact on the energy transition. The result still holds after a series of robustness tests. Further analysis shows that the adverse impact of climate policy uncertainty on the energy transition weakens with more proactive government behavior and greater public environmental concerns. For cities that are economically underdeveloped, non-resource oriented and officials' promotion pressure mounting, the disincentive to energy transition is greater when climate policy uncertainty rises.

Industrial water consumption index: A new bridge between water consumption and socioeconomic development

Regional water consumption is closely linked to socioeconomic development trends; however, studies that analyze and evaluate socioeconomic development trends based on water consumption data are lacking. This study established a new general index, the industrial water consumption index (IWCI), using several variables from water consumption data through the entropy weight method and tested the index in Jiaxing City, China. The results showed that the relationship between water consumption and socioeconomic development varied depending on different industrial divisions. The IWCI, established based on water consumption data was highly sensitive to changes in socioeconomic development, especially rapid changes. Compared to the raw water consumption data, the IWCI presented a better performance in evaluation indicators for the selected several divisions, with a Pearson correlation coefficient ranging from 0.70 to 0.85 and a normalized mutual information ranging from 0.31 to 0.45. Overall, the IWCI provides an effective way to evaluate socioeconomic development trends by relying solely on water consumption data, particularly for industrial divisions where water plays an important role in production. The index allows managers to quickly assess and analyze socioeconomic development trends and develop corresponding response measures.

Unveiling the development trends of environmental and human health concerns for pesticides: Integrating an intelligent approach and data mining across diverse databases

The impact of pesticide use on environmental and human health has been a persistent global concern. In the era of big data, the scientific literature concerning big data is a significant source of information; however, it is difficult to construct an optimal policy based on traditional insight using keyword searches or a single static-specialized database. In this study, we constructed a new path for data mining across multiple databases to provide a comprehensive picture of the major issues concerning environmental pollution and human health as a result of pesticide use at the global scale. This approach uses a classic unsupervised learning algorithm, Latent Dirichlet Allocation (LDA), in combination with a newly developed dataset of pesticide-associated human health outcomes (PAHHO), including 618 health outcomes classified into 14 types of toxic effects.Our data visualization revealed a shift in the scientific center for pesticide research over the past five decades. The major issues concerning environmental pollutants and health outcomes varied among different countries and in different periods, which was verified in our analysis of several organochlorine pesticides (OCPs) about which people are particularly concerned.A cooccurrence network of adverse health outcomes has gradually increased, suggesting that the impact of pesticides on human health is persistent and cumulative. Our work not only provides a promising research direction related to the most concerning issues in a systematic and visualized way but also provides valuable references to formulate optimal strategies for the goal of the global “One Health” objective in pesticide regulation.

Measurement of new qualitative productivity kinetic energy from the perspective of digital and green collaboration --Comparative study based on European countries

At present, the world is witnessing the historic convergence of a new round of scientific and technological revolution and industrial change with the transformation of the development mode, and it is strategically important and far-reaching to rapidly enhance new qualitative productivity kinetic energy (NQPKE) on the basis of the lessons learning from the experience of the pioneering countries for all countries, so as to expand the room for manoeuvre of the economic development, obtain the initiative of international competition, and realize the benign interaction of high-quality development and high-level of security. On the basis of analysing the formation mechanism of NQPKE, we characterize NQPKE by the coupling and coordination degree of digital productivity and green productivity, we analyse NQPKE by using the entropy weight TOPSIS method and the coupling and synergistic model, and analyse the spatial-temporal characteristics, steady state development and constraints of NQPKE by using the method of kernel density estimation, the Markov chain, the spatial Markov chain, and the obstacle degree model based on data from 21 European countries from 2009-2022. The study finds that: (1) The NQPKE shows a wave-like development trend, and the polarization or multi-polarization state of the whole and the four major regions has been slowly weakened, with a certain degree of "club convergence" and "spatial spillover"; (2) The overall situation of barriers to NQPKE is relatively stable, the insufficient investment in scientific and technological development and weak technological innovation capacity are the most critical factors constraining the NQPKE in various countries. Based on the above conclusions, the article proposes to hold high the banner of peaceful development and win-win cooperation, give full play to the "club convergence" and "spatial spillover" effects of NQPKE, accelerate the development of NQPKE adapt to local conditions, and the "digital + green" double base will stimulate technological innovation, and the construction of a digital and green synergistic management system stimulates the potential of the new quality productivity of enterprises, ultimately unleash the surging kinetic energy of new quality productivity development.
