Core Viewpoint - The book "Restoring the Scientific Nature of Economic Research" emphasizes the importance of scientific methodology in economic research, highlighting the need for accurate concepts, reliable data, logical reasoning, and historical analysis to understand economic phenomena [2][3][4]. Group 1: Scientific Methodology in Economic Research - The author summarizes the scientific methodology of economic research with four key elements: concepts, data, logic, and history [3]. - Accurate understanding of economic concepts is crucial, as misinterpretations can lead to flawed conclusions and the emergence of unconventional economic theories [3][4]. - Data must substantiate viewpoints; without empirical support, opinions remain ungrounded [4]. Group 2: Importance of Historical Data - Historical data is vital in economic research due to the irreversible nature of time and circumstances, allowing researchers to analyze past "experiments" to identify common patterns [5]. - The book discusses how to analyze historical economic patterns, emphasizing that optimal economic growth rates should align with a country's potential growth rate, which varies across different development stages [6]. Group 3: Analysis of Economic Phenomena - The author analyzes various economic phenomena, including fiscal policy, real estate, and the internationalization of the Renminbi, stressing the need to understand the cyclical and trend-based nature of economic operations [7]. - A recommendation is made for systematic reform of fiscal policy to enable counter-cyclical adjustments, moving away from a pro-cyclical behavior model [7].

Development Stages of Special Bonds - Special bonds have undergone four main stages since their inception in 2015: exploration (2015-2018), innovation and expansion (2019-2021), transformation and regulation (2022-2024), and optimization and improvement (from late 2024) [3][4][6][18]. - In the innovation and expansion phase (2019-2021), the issuance of special bonds rapidly increased, with new quotas rising from CNY 1.35 trillion in 2018 to CNY 3.75 trillion in 2020 [25][26]. Current Characteristics and Usage - As of 2024, 40.5% of special bonds were allocated for new project construction, while 40.4% were used for debt replacement, and 19.2% for repaying maturing bonds [7]. - The proportion of special bonds used as project capital has been increasing, reaching 9.8% in 2024, with a policy cap of 30% [7]. Challenges and Issues - Special bonds have faced issues such as unclear positioning, with projects lacking revenue being funded by general debt, while high-revenue projects are left to market mechanisms [9]. - The allocation of special bond quotas often reflects the distribution of hidden debts rather than efficiency, which undermines the intended positive incentives [9]. Recommendations for Improvement - It is recommended to clarify the positioning of special bonds to ensure they are used for projects that can cover their own costs, thus preventing pressure on general public budgets [13]. - The distribution of quotas should prioritize high-quality projects in regions with population inflows and strong industrial bases, while using general debt for areas with declining populations [13].
